  1. For those of you who don't know me, my name is Sean.

  2. I'm one of the pastors of Trinity Cambridge Church.

  3. It's my great joy and privilege to preach God's word to you this morning.

  4. We are in the Gospel of Matthew, which is the first book in the New Testament.

  5. We're in chapter 5 today.

  6. We just finished the Beatitudes.

  7. We're in Matthew 5, verses 13 to 16.

    Matthew 5:13–16

  8. Let me pray for the reading and preaching of God's word.

  9. Heavenly Father,

  10. Father, you have redeemed us at a steep price,

  11. the blood of your only Son, Jesus Christ.

  12. And we belong to you.

  13. And you have adopted us as your children.

  14. And as your children, it is only fitting that we resemble you and represent you.

  15. And so we want to be, as Jesus says here, salt and light of the world.

  16. Refresh us.

  17. Renew us.

  18. Help us to remember

  19. Jesus and what he has done for us.

  20. So that we might leave this place this morning

  21. a little more salty,

  22. shining a little more bright

  23. than perhaps we have been this past week.

  24. Glorify your name, God,

  25. in the reading and preaching of your word.

  26. In Jesus' name we pray.

  27. Amen.

  28. If you are able, please stand

  29. to honor God as we read from his word.

  30. Matthew 5, verses 13 to 16.

    Matthew 5:13–16

  31. You are the salt of the earth.

  32. But if salt has lost its taste,

  33. how shall its saltiness be restored?

  34. It is no longer good for anything

  35. except to be thrown out and trampled under people's feet.

  36. You are the light of the world.

  37. A city set on a hill cannot be hidden,

  38. nor do people light a lamp and put it under a basket,

  39. but on a stand,

  40. and it gives light to all in the house.

  41. In the same way,

  42. let your light shine before others

  43. so that they may see your good works

  44. and give glory to your Father who is in heaven.

  45. This is God's holy and authoritative word.

  46. Please be seated.

  47. John Lennon was a member

  48. of the 20th century English rock band, The Beatles.

  49. And in one of his most famous songs, Imagine,

  50. he tells his listeners to imagine a world

  51. where there is no religion.

  52. And he says that in such a world,

  53. there's no heaven, no hell below us.

  54. He claims that there will be nothing to kill or die for

  55. and that there would be worldwide peace.

  56. Sung over a beautiful piano motif,

  57. the sentiment seems more plausible than it actually is

  58. because it's a hollow statement

  59. that betrays a shallow understanding

  60. of the human condition.

  61. The self-centeredness that is at the root

  62. of all social ills in the world

  63. resides in the human heart.

  64. The problem is man, not religion.

  65. It's man's sin-sick heart that twists everything,

  66. including religion, for its selfish purposes.

  67. The solution then is not no religion,

  68. but true religion.

  69. Truth that sets us free.

  70. Truth that heals our sin-sick hearts.

  71. And that truth is the gospel of Jesus Christ.

  72. The people who believe the gospel, Jesus says,

  73. are the salt of the earth and the light of the world.

  74. Salt preserves food and it flavors food.

  75. Imagine food that is bland and rotting without salt.

  76. That's Jesus' provocative claim

  77. that that's what this world would be like

  78. without Christians.

  79. Light, like salt, is an essential ingredient of life.

  80. It drives out darkness.

  81. It enables us to see.

  82. Imagine a world without the sun

  83. or without any of the artificial lights that we have.

  84. Dark, dreary, cold.

  85. That's what the world would be like

  86. without the light of God that shines through his people.

  87. My main point this morning is this,

  88. that we must let our distinctive identity as Christians

  89. shine in order to bring glory to our Father in heaven.

  90. So first, we'll talk about the salt of the earth,

  91. and then second, we'll talk about the light of the world.

  92. Jesus says in verse 13,

  93. you are the salt of the earth.

  94. This marks an important transition from the Beatitudes.

  95. The Beatitudes were all phrased

  96. in the third person plural forms.

  97. If you look back at the few verses before this,

  98. it said, blessed are those

  99. who are persecuted for righteousness' sake.

  100. But then in the second half of that last Beatitude,

  101. verses 11 and 12,

  102. it switched to the second person plural.

  103. Blessed are you when others revile you

  104. and persecute you.

  105. This transition prepares the way for today's passage,

  106. which says you are the salt of the earth.

  107. You are the light of the world.

  108. The Beatitudes described who Christians are.

  109. Their identity.

  110. But the rest of the Sermon on the Mount

  111. now describes what Christians do.

  112. How they live.

  113. It's from our identity,

  114. who we are in Jesus Christ,

  115. that our obedience to his commands flow.

  116. This follows a pattern of the Ten Commitments.

  117. You may recall when we first started our series

  118. in the Beatitudes seven weeks ago,

  119. I mentioned that Jesus going up on the mountain

  120. to speak God's new law parallels Moses going up on the mountain

  121. to bring God's law,

  122. to receive the Ten Commandments

  123. and the subsequent explanations of it.

  124. The Ten Commandments doesn't begin with the First Commandment.

  125. It actually begins with the preamble,

  126. which establishes who God is and who God's people are.

  127. I am the Lord, your God,

  128. who brought you out of Egypt from the land of slavery.

  129. It begins with the identity of God's people

  130. as the redeemed people of God.

  131. And Beatitudes likewise serve as the preamble to the Sermon on the Mount.

  132. It begins,

  133. it tells us by showing us who we are.

  134. We are people who are poor,

  135. mourning,

  136. meek,

  137. and hungry.

  138. We are people who have received God's mercy and purity

  139. and peace and righteousness in Jesus Christ.

  140. That's who we are as Christians.

  141. It's only after telling us who we are,

  142. Jesus goes on to tell us what we must do.

  143. So Matthew 5, 13 to 16 is a transitional passage

  144. to the ethical sections of the Sermon on the Mount.

  145. You are the salt of the earth.

  146. And that it's an emphatic you,

  147. personal pronoun.

  148. You, not they.

  149. You, yourselves,

  150. are the salt of the earth,

  151. the light of the world.

  152. So what does it mean to be the salt of the earth?

  153. Salt in many ways is a humble condiment, right?

  154. Any restaurant you go to,

  155. any Western household you go to,

  156. you'll find a little table salt,

  157. shaker up full of table salt.

  158. But it's only in the last 150 years, actually,

  159. that salt became cheap and commonplace.

  160. Because of the advancement in the mining technologies

  161. and evaporating salt and all that.

  162. But before that,

  163. there's actually an entire book dedicated to salt

  164. by Mark Kralansky.

  165. It's called Salt, A World History.

  166. I know, it sounds like I haven't read the whole thing,

  167. but it's an interesting idea.

  168. He writes that human civilization has been shaped by this simple mineral.

  169. Wars were fought over salt reserves as early as 6,000 BC in China.

  170. Salt was the first international trade good.

  171. And ancient Mesopotamians and Egyptians and Romans used salt as currency.

  172. In fact, that's where we get the English word salary,

  173. which is derived from the Latin word salarius,

  174. which means of salt,

  175. because the Romans paid their soldiers in salt.

  176. Why was salt so valuable and cherished throughout human history?

  177. Two main reasons.

  178. One, salt is essential for human survival, for life.

  179. Salt is crucial for hydration,

  180. maintaining blood pressure,

  181. nerve impulse transmission,

  182. muscle contraction,

  183. heart function,

  184. and hormonal regulation,

  185. digestion,

  186. bone health,

  187. immune function,

  188. and so on.

  189. Severely low sodium levels in our bodies

  190. lead to muscle cramps and nausea

  191. and vomiting and dizziness

  192. and eventually to shock,

  193. coma,

  194. and death.

  195. This is why many endurance athletes carry

  196. not only water,

  197. but salt tablets.

  198. Salt is something that our bodies need.

  199. And yet, interestingly enough,

  200. it's something that our bodies are incapable of producing on its own.

  201. It must come from an external source

  202. in the same way we receive God's grace and mercy from elsewhere,

  203. not from within ourselves.

  204. So that's one reason salt is precious.

  205. Second reason is that salt is essential for flavoring and preserving food.

  206. Nobody likes bland food,

  207. and salt makes food tasty.

  208. Even more importantly,

  209. ancient Egyptians,

  210. I think,

  211. were one of the earliest people to discover

  212. that salt kills bacteria in certain foods,

  213. and they learned that because it extracts moisture

  214. and it kills bacteria,

  215. it preserves food to make it last significantly longer

  216. than it otherwise would.

  217. That process we call curing,

  218. which is commonly used for meats and fish and cheeses.

  219. I'm sure you've had some cured ham recently,

  220. or bacon.

  221. In the days before refrigeration,

  222. salt could mean the difference

  223. between edible food and spoiled food,

  224. which then would mean the difference

  225. between life or death.

  226. This antibacterial property of salt

  227. was also an effective antiseptic,

  228. made it an effective antiseptic,

  229. and many ancient civilizations used it to clean wounds

  230. and prevent infections,

  231. which is where we get the expression,

  232. rubbing wound on your salt,

  233. which kind of has a bad connotation now.

  234. But when you don't have other things to use,

  235. it helps.

  236. Even now,

  237. I think some of you rinsed your throats,

  238. mouths,

  239. with salt water

  240. when you have canker sores in your mouth.

  241. In light of this historical background,

  242. what does it mean that followers of Christ

  243. are to be salt of the earth?

  244. You know to understand that,

  245. we must first address

  246. what this is implying about the world.

  247. By saying that we are the salt of the earth,

  248. Jesus is saying that the earth,

  249. the rest of the earth,

  250. is not salt,

  251. and that it needs salt.

  252. It means first that the world is bland,

  253. and then needs flavoring,

  254. and it also means that the world is putrefying.

  255. It is rotting,

  256. and it must be preserved.

  257. Ever since sin first entered the world,

  258. our world has been decaying and dying,

  259. and therefore,

  260. it needs salt,

  261. people who are salt,

  262. as a preservative and an antiseptic.

  263. The world,

  264. left on its own,

  265. has a tendency to fester,

  266. unless God's people arrest

  267. the continual decay.

  268. In Genesis 6, 5,

  269. it says,

  270. the Lord saw that the wickedness of man

  271. was great in the earth,

  272. and that every intention of the thoughts

  273. of his heart was only evil continually.

  274. It's this reality that leads God

  275. to bring down the flood judgment

  276. during Noah's day.

  277. And why was the world in such a state?

  278. In Genesis 6,

  279. it tells us in verse 8 to 9,

  280. it says that only Noah

  281. was a righteous man who walked with God,

  282. while the rest of mankind was corrupt,

  283. for all flesh had corrupted their way on the earth.

  284. Why did it come to such a dire point?

  285. Because there's not enough salt on the earth.

  286. If you do a concordance search

  287. for the word salt in the Bible

  288. and find references to salt in the Bible,

  289. you'll find an interesting phrase

  290. that occurs several times.

  291. It's a covenant of salt.

  292. God refers to his covenant

  293. with his chosen people

  294. as a covenant of salt.

  295. The reason why is because

  296. of salt's preserving property.

  297. It became a symbol of endurance,

  298. symbol of permanence.

  299. And so when people in the Arab world,

  300. in the ancient Near East,

  301. would make a covenant with other people,

  302. they would often eat salt together

  303. to symbolize this is a covenant

  304. that's meant to last.

  305. Like salt.

  306. So he says in Leviticus 2.13,

  307. you shall season all your grain offerings

  308. with salt.

  309. You shall not let the salt of the covenant

  310. with your God be missing

  311. from your grain offering.

  312. With all your offerings,

  313. you shall offer salt.

  314. Salt had to accompany

  315. every grain offering.

  316. In this way,

  317. in Scripture,

  318. salt becomes a powerful symbol

  319. of our covenant relationship with God.

  320. So in light of that,

  321. then what does it mean for us

  322. to be salt of the earth?

  323. It means to be a people

  324. who are loyal to God.

  325. People who are obedient to God.

  326. To be representatives of God.

  327. To be people who preserve the earth

  328. as it should be,

  329. reflecting on the earth

  330. the righteousness of God

  331. and resisting

  332. the decay and death

  333. of sin.

  334. But we can only do that

  335. if we remain salty.

  336. Jesus says in verse 13,

  337. but if salt has lost its taste,

  338. how shall its saltiness be restored?

  339. It is no longer good for anything

  340. except to be thrown out

  341. and trampled under people's feet.

  342. The chemists in the room

  343. can tell you guys

  344. that salt doesn't lose its saltiness

  345. because as soon as,

  346. Bailey's nodding over there,

  347. as soon as salt loses its saltiness,

  348. it would cease to be salt

  349. because its chemical composition

  350. would be changed.

  351. But that defeats the point

  352. of the metaphor,

  353. so don't go there.

  354. In this part of the ancient world,

  355. salt was likely derived

  356. from the Dead Sea

  357. or from the ocean nearby

  358. and there would often be

  359. other residue and minerals

  360. that are mixed in with salt.

  361. So there would be

  362. some salt-like things,

  363. minerals that are extracted

  364. that people would use as salt

  365. but they would actually have no taste

  366. because it wasn't salt.

  367. So if salt has been diluted

  368. or it has been mixed

  369. with these other minerals,

  370. it would be useless

  371. for preserving or flavoring food.

  372. And once salt loses its taste,

  373. its saltiness cannot be restored.

  374. It's really good for nothing.

  375. The phrase lost its taste,

  376. interestingly in Greek,

  377. which is the language

  378. that the New Testament

  379. is written in,

  380. the phrase lost its taste

  381. literally means

  382. to become foolish.

  383. Isn't that fascinating?

  384. The reason why

  385. this unusual Greek word

  386. is used

  387. to mean lose its taste

  388. is because

  389. in the original Aramaic

  390. that Jesus would have spoken

  391. and in the related language

  392. of Hebrew,

  393. the word for tasteless

  394. also means foolish

  395. or wrong.

  396. For example,

  397. in Jeremiah 23, 13,

  398. the Lord says,

  399. in the prophets of Samaria,

  400. I saw an unsavory thing,

  401. a tasteless thing.

  402. They prophesied by Baal

  403. and led my people Israel astray.

  404. That tasteless thing

  405. is translated

  406. by other translations

  407. as folly

  408. or that offensive thing

  409. or the repulsive thing.

  410. In Lamentations 2, 14,

  411. that same word

  412. is translated

  413. as deceptive visions

  414. or worthless things

  415. or foolish things

  416. that prophets,

  417. the false prophets prophesy.

  418. In Job 1, 22,

  419. and 24, 12,

  420. that tasteless thing

  421. is used to refer to

  422. an offense

  423. or a wrong

  424. that someone

  425. can be charged with.

  426. And perhaps

  427. most suggestively,

  428. throughout the prophetic literature,

  429. especially in Ezekiel 13,

  430. that same word,

  431. that tasteless thing

  432. refers to the whitewash

  433. that people use

  434. to hide blemishes

  435. and dirt

  436. and grime

  437. and mold

  438. on walls

  439. because that's an unseemly

  440. and an offensive practice

  441. to whitewash

  442. something like that

  443. instead of actually

  444. cleaning it

  445. and getting rid of

  446. the mold

  447. and the grime.

  448. So that's what it means

  449. for the salt

  450. to lose its taste,

  451. for it to be tasteless.

  452. To lose our taste

  453. as salt,

  454. as believers,

  455. is to become foolish.

  456. To lose sight

  457. of the wisdom of God.

  458. To become complicit

  459. with the repulsiveness

  460. and the offensiveness

  461. of idolatry

  462. in our world.

  463. to lose our distinctive

  464. identity as Christians.

  465. To blend in

  466. to this sinful world

  467. instead of

  468. standing out.

  469. It means to whitewash

  470. the evils

  471. of our world

  472. and to call them good.

  473. G.K. Chesterton

  474. once wrote about

  475. this folly

  476. in his book,

  477. Orthodoxy.

  478. He says,

  479. what is the evil

  480. of the man

  481. commonly called

  482. an optimist?

  483. Obviously,

  484. it is felt

  485. that the optimist

  486. wishing to defend

  487. the honor of this world

  488. will defend

  489. the indefensible.

  490. He will not

  491. wash the world

  492. but whitewash

  493. the world.

  494. That's what it looks like

  495. for salt

  496. to lose its taste.

  497. Christians who have

  498. lost their saltiness

  499. are no longer

  500. distinguishable

  501. from the rest

  502. of the world.

  503. They justify

  504. the sins of the world.

  505. Their values

  506. and priorities

  507. are not aligned

  508. with God's

  509. unchanging word.

  510. Rather,

  511. it is aligned

  512. with the ever-changing

  513. culture.

  514. But the church

  515. that represents

  516. God and Jesus

  517. must be set apart,

  518. must be holy.

  519. In order for us

  520. to be a city

  521. on a hill

  522. and light in the darkness,

  523. the salt of the earth,

  524. we must be

  525. an alternate community,

  526. a contrast community.

  527. Let me give a few

  528. examples

  529. as practical application

  530. points.

  531. Does the way

  532. you talk

  533. distinguish you

  534. from the way

  535. the world speaks?

  536. Maybe the conversations

  537. in your workplace

  538. are usually vulgar

  539. and obscene

  540. and profane.

  541. Maybe it's full

  542. of gossip

  543. and slander

  544. about your coworkers,

  545. but when you come

  546. into the office space,

  547. people start

  548. talking differently.

  549. They start

  550. watching what

  551. they say.

  552. They stop

  553. taking the Lord's

  554. name in vain.

  555. They stop

  556. talking about

  557. lewd subjects.

  558. They stop

  559. swearing nonstop.

  560. They stop

  561. gossiping

  562. about their coworkers

  563. because they know

  564. that you don't join

  565. in on that kind

  566. of talk.

  567. you are being

  568. salt of the earth,

  569. restraining sin

  570. and preserving

  571. the earth.

  572. How do you

  573. interact with people

  574. that you disagree

  575. strongly with?

  576. Do you

  577. caricature

  578. your opponent's

  579. position

  580. to make it

  581. sound as

  582. unreasonable

  583. as possible?

  584. Do you

  585. cancel

  586. and dox them?

  587. when you

  588. listen well

  589. to your opponents

  590. and you represent

  591. their positions

  592. fairly and when

  593. you reason with

  594. them instead of

  595. canceling them,

  596. you are functioning

  597. as salt and

  598. slowing the rapid

  599. deterioration of

  600. dialogue in our

  601. culture.

  602. Is your media

  603. consumption different

  604. from that of the

  605. rest of the world?

  606. According to the

  607. Pew Research Center,

  608. 62% of U.S.

  609. adults identify

  610. as Christians.

  611. Christians.

  612. That number is

  613. very, very

  614. inflated because

  615. there are many

  616. cultural and

  617. nominal Christians

  618. who on surveys

  619. like that say

  620. they are Christian

  621. but don't actually

  622. do anything in

  623. their life that

  624. resembles what a

  625. Christian should

  626. look like because

  627. they don't actually

  628. believe what the

  629. Bible teaches and

  630. don't actually live

  631. according to what

  632. the Bible says.

  633. But imagine

  634. with me,

  635. if 62% of

  636. U.S.

  637. adults were

  638. really Christians,

  639. if 62% of

  640. U.S.

  641. Christians

  642. refused to,

  643. U.S.

  644. adults refused to

  645. watch gratuitously

  646. violent and

  647. sexually explicit

  648. and or occultic

  649. horror films and

  650. shows,

  651. do you think that

  652. Hollywood keep

  653. churning out those

  654. kinds of movies

  655. when 62% of the

  656. population refuses to

  657. watch them?

  658. Of course not.

  659. It affects their

  660. bottom line way too

  661. much.

  662. they produce those

  663. kinds of shows and

  664. movies because

  665. Christians gobble

  666. them up like the

  667. rest of the world

  668. because their salt

  669. has lost its taste.

  670. Does the way you

  671. spend your money

  672. distinguish you from

  673. the way the world

  674. spends money?

  675. Of course some

  676. basic things and

  677. basic needs are

  678. going to look the

  679. same.

  680. We all need food and

  681. clothing and shelter.

  682. But beyond those

  683. basic needs, if we

  684. really store up our

  685. treasures in heaven

  686. and not on earth, if

  687. we are invested in

  688. not just temporal

  689. priorities but in

  690. eternal priorities,

  691. then it should show

  692. in our budget.

  693. It should show in our

  694. generosity toward the

  695. needy around us.

  696. It should be apparent

  697. to the people of this

  698. world that, oh,

  699. these Christians don't

  700. treasure the same

  701. thing that I

  702. treasure.

  703. If we are

  704. indistinguishable from

  705. unbelievers at this

  706. point, then the salt

  707. has lost its taste.

  708. How sad it is when

  709. those who are called

  710. by the name

  711. Christian are the

  712. indistinguishable from

  713. the non-Christians.

  714. A tasteless salt cannot

  715. flavor.

  716. It no longer absorbs

  717. water and kills

  718. bacteria.

  719. It cannot preserve

  720. food.

  721. And a Christian who

  722. exhibits no Christian

  723. character, a Christian

  724. who does not uphold

  725. Christian convictions,

  726. is no longer good for

  727. anything except to be

  728. thrown out and trampled

  729. under people's feet.

  730. This is a fearful

  731. warning.

  732. That's not a good

  733. thing.

  734. Being trampled under

  735. people's feet is a

  736. mark of destruction.

  737. In Luke 8, the

  738. parable of the sower,

  739. the seed that falls

  740. along the path and

  741. is subsequently

  742. trampled by men and

  743. then consumed by

  744. birds, Jesus says, is

  745. an illustration of

  746. people who hear the

  747. gospel, but then that

  748. gospel seed is snatched

  749. away by the devil and

  750. it does not, they do

  751. not believe from their

  752. hearts.

  753. Salt that has lost its

  754. taste is useless salt.

  755. In fact, it's no true

  756. salt at all.

  757. Jesus switches metaphors

  758. in verse 14.

  759. He says, you are the

  760. light of the world.

  761. Once again, what we do

  762. flows from who we are.

  763. Our identity is you are

  764. the light of the world

  765. and that's a remarkable

  766. claim because Jesus is

  767. speaking here to his

  768. ragtag group of

  769. disciples, the ordinary

  770. fishermen, the tax

  771. collector.

  772. Jesus didn't say, oh,

  773. Socrates, Plato,

  774. Aristotle, Homer,

  775. Caesar, Augustus,

  776. they're the light of the

  777. world.

  778. The world speaks often

  779. of enlightenment.

  780. It speaks often of

  781. luminaries or geniuses of

  782. history who are the light

  783. of the world.

  784. The world speaks often of

  785. stars, but it's not the

  786. Grammy winners and the

  787. Oscar winners and the

  788. election winners and the

  789. gold medal winners and

  790. championship winners and

  791. the billionaires in the

  792. world that they, the

  793. people who have their

  794. names on the Hollywood

  795. Walk of Fame, who have a

  796. star on the walk of

  797. them.

  798. They are not the stars of

  799. this world.

  800. They are not the light of

  801. this world.

  802. You are the people of

  803. God.

  804. You are the light of the

  805. world.

  806. You are the people who can

  807. shine the light of Jesus

  808. Christ in this dark world.

  809. You are the people whose

  810. good deeds, whose

  811. righteousness will check the

  812. progress of death and

  813. decay in our world.

  814. You are the hope of the

  815. earth.

  816. Do you believe this,

  817. brothers and sisters?

  818. I believe that with all

  819. my heart, and that's why

  820. I've given my life to

  821. serve the church of

  822. Christ.

  823. But, brothers and

  824. sisters, I did not choose

  825. a humble profession.

  826. I chose to serve the

  827. king of kings.

  828. I chose to be associated

  829. with and to work among

  830. the stars, the light of

  831. the world.

  832. In fact, the only light.

  833. The fact that the

  834. follower of Christ are the

  835. light of the world implies

  836. something obvious, again,

  837. that this sinful world is

  838. now lost.

  839. It's plunged in darkness.

  840. It is full of sin and

  841. evil.

  842. The world is full of

  843. knowledge of various

  844. kinds.

  845. Every time a PhD

  846. dissertation is written,

  847. it seems like we make

  848. some marginal progress

  849. toward more knowledge.

  850. Yet, for all of its

  851. knowledge, the world

  852. profoundly lacks the

  853. wisdom of God.

  854. It understands much

  855. about things that are

  856. immediate, but it

  857. understands very little

  858. about the things that

  859. are ultimate.

  860. Think about this.

  861. People are more

  862. connected to each other

  863. than they ever were

  864. before, by fast travel,

  865. by social media, by

  866. distance communication.

  867. Yet, people are

  868. lonelier than they ever

  869. were.

  870. No matter how

  871. intelligent or rich or

  872. talented the people of

  873. this world might be,

  874. Ephesians 4.18

  875. describes those who

  876. live apart from Christ as

  877. darkened in their

  878. understanding, alienated

  879. from the life of God

  880. because of the

  881. ignorance that is in

  882. them due to their

  883. hardness of heart.

  884. For this reason, only

  885. those who humbly

  886. acknowledge their

  887. ignorance and darkness

  888. and come to Christ can

  889. receive his light and

  890. become the light of the

  891. world.

  892. That's why in the

  893. Beatitudes, Jesus

  894. describes Christians as

  895. those who are poor and

  896. mourning and meek and

  897. hungering and thirsting

  898. for righteousness because

  899. they recognize their

  900. deficiency.

  901. They recognize their

  902. neediness.

  903. They recognize their

  904. lack.

  905. And those who have

  906. become the light of the

  907. world, they shine.

  908. A city set on a hill

  909. cannot be hidden, nor do

  910. people light a lamp and

  911. put it under a basket, but

  912. on a stand, and it gives

  913. light to all in the

  914. house.

  915. When a city is nestled in

  916. a valley, it can be

  917. hidden by the hills that

  918. surround it, but if a

  919. city is on top of a

  920. hill, all eyes gravitate

  921. toward it.

  922. There's nothing you can do

  923. to hide it.

  924. Likewise, people do not

  925. light a lamp and then

  926. put it under a basket.

  927. They put it on a stand

  928. so that it gives light to

  929. everyone in the house.

  930. That is the very purpose

  931. of light, to shine.

  932. If you're going to put

  933. your light under a basket

  934. and hide it, why have it

  935. turned on in the first

  936. place?

  937. Jesus is saying that this

  938. is the very nature and

  939. purpose of Christians.

  940. As salt that has lost its

  941. taste is useless, so a

  942. light that is hidden and

  943. fails to give light is

  944. useless.

  945. What good is an

  946. extinguished candle or a

  947. burnt-out light bulb?

  948. So a Christian who is

  949. indistinguishable from the

  950. world, whose life bears no

  951. witness to Jesus Christ, is

  952. useless.

  953. The best way to understand

  954. what it means to be the

  955. light of the world is to

  956. make the connection that

  957. Matthew himself makes in

  958. his gospel because earlier

  959. in chapter 4, verse 16, he

  960. wrote that Jesus, about the

  961. coming of Jesus, that Jesus

  962. himself is the one who

  963. fulfills the prophecy of

  964. Isaiah 9, verse 2, which

    Isaiah 9:2

  965. says that people dwelling in

  966. darkness have seen a great

  967. light.

  968. And that's why Jesus claimed,

  969. an audacious claim really,

  970. if it's, he said in John 8,

  971. 12, I am the light of the

  972. world.

  973. Whoever follows me will not

  974. walk in darkness, but will

  975. have the light of life.

  976. In order to have the light

  977. of life, you must follow

  978. Jesus, the light of the

  979. world.

  980. Second Corinthians 4, 4-6,

  981. Paul speaks of the light of

  982. the gospel of the glory of

  983. Christ, who is the image of

  984. God.

  985. So Christians are those who

  986. have believed in the gospel or

  987. the good news of Jesus

  988. Christ.

  989. Do you acknowledge that the

  990. world is dark?

  991. Do you acknowledge that your

  992. ways are darkness?

  993. God the Father sent his only

  994. son, Jesus Christ, into this

  995. world in order to deliver us,

  996. deliver us, as it says in

  997. Colossians, from the dominion

  998. of darkness into the kingdom

  999. of his beloved son.

  1000. God, we were, no matter how

  1001. much we claim to say, well, I

  1002. have eyes, I am not blind.

  1003. No matter how good your

  1004. eyesight is, without light, you

  1005. can not see a thing.

  1006. So it is in the spiritual world.

  1007. Unless the light of Jesus

  1008. Christ shines upon us, you

  1009. cannot see.

  1010. We were groping about in the

  1011. darkness, lost in sin and

  1012. destined for death and hell and

  1013. unable to save ourselves,

  1014. unable to pull ourselves up by

  1015. our own bootstraps.

  1016. And it's in that place that

  1017. Jesus came.

  1018. God the Father sent his son,

  1019. Jesus Christ, as the light of

  1020. the world to illumine our

  1021. darkness so that we might

  1022. believe in him who died on the

  1023. cross for our sins, who bore

  1024. our darkness and carried our

  1025. darkness and buried it and

  1026. rose from the dead so that we

  1027. can sing and say, I once was

  1028. blind, but now I see.

  1029. And it's when our spiritual eyes

  1030. are open to the light of the

  1031. gospel of Jesus Christ that we

  1032. too begin to shine.

  1033. It's like we are all a thousand

  1034. candles being brought to Jesus,

  1035. the light of the world, and being

  1036. lit aflame.

  1037. It's by our union with Jesus

  1038. Christ, by faith, that we become

  1039. light of the world.

  1040. And the amazing thing about light

  1041. and the amazing thing about fire

  1042. is when you spread it, it doesn't

  1043. get extinguished in its original

  1044. source, no, it multiplies.

  1045. And once we have this light, we can't

  1046. help but shine.

  1047. That's why following Christ is not

  1048. merely about personal, private

  1049. holiness.

  1050. There's always a public witness

  1051. component.

  1052. In fact, if there is true, genuine

  1053. personal holiness, inevitably there

  1054. will be interpersonal witness.

  1055. Because people will notice.

  1056. It says in verse 16, in the same

  1057. way, let your light shine before

  1058. others so that they may see your

  1059. good works and give glory to your

  1060. Father who is in heaven.

  1061. What does it mean that we are to

  1062. shine before others so that they

  1063. praise their Father?

  1064. It tells us, it tells us that they

  1065. will see our good works and give

  1066. glory to our Father who is in

  1067. heaven.

  1068. So the emphasis on this passage is

  1069. on the good works that we do in

  1070. response to the good news that we

  1071. believe in.

  1072. Light's primary function is to

  1073. enable us to see, as we mentioned,

  1074. right?

  1075. And how do we point people to the

  1076. saving light of the gospel of the

  1077. glory of Christ?

  1078. Titus 2.10 says that one of the

  1079. ways we do that is by adorning the

  1080. doctrine of God our Savior with the

  1081. good works that we do.

  1082. So yes, as Christians, we must speak

  1083. the good news, but we are also to

  1084. adorn that good news that we speak by

  1085. the good works that we do.

  1086. And what do these good works look

  1087. like?

  1088. It looks like what Jesus talks about

  1089. in the rest of the Sermon on the

  1090. Mount.

  1091. It's not always spectacular things.

  1092. It looks like being patient and

  1093. gentle when you can lash out at

  1094. somebody in sinful anger.

  1095. It looks like being self-controlled

  1096. rather than lustful.

  1097. It looks like being faithful to your

  1098. spouse for a lifetime rather than

  1099. divorcing him or her or committing

  1100. adultery.

  1101. It looks like not retaliating, but

  1102. loving and praying for your enemies.

  1103. It looks like giving to the needy in

  1104. secret.

  1105. It looks like trusting God rather than

  1106. being anxious.

  1107. It looks like serving God rather than

  1108. serving money.

  1109. It looks like praying for God's will to

  1110. be done on earth as it is in heaven.

  1111. It looks like, in short, loving God with

  1112. our whole hearts and loving our neighbors

  1113. as we love ourselves.

  1114. That's what it looks like for us to do

  1115. good works that shine, that shine our

  1116. light.

  1117. I can also point to many examples from

  1118. history that are maybe perhaps a little

  1119. more spectacular, although they didn't

  1120. happen necessarily in spectacular ways.

  1121. Looking back, they look spectacular.

  1122. Historian Alvin Schmidt points this out in

  1123. his book, How Christianity Changed the

  1124. World, and he says that Christian

  1125. influence on government and not all of

  1126. these happen through the legislations.

  1127. It just happened by multiplying

  1128. Christians in these places so that more

  1129. and more people thought these ways and

  1130. started acting these ways.

  1131. But he says that Christian influence in

  1132. the world is primarily responsible for, he

  1133. says, outlawing infanticide, child

  1134. abandonment and abortion and gladiatorial

  1135. games in the Roman Empire, instituting

  1136. prison reforms, something as basic as

  1137. segregating male and female prisoners,

  1138. stopping the practice of human sacrifice

  1139. among the Irish, the Prusians, and the

  1140. Lithuanians as well as among other

  1141. nations, outlawing pedophilia, granting

  1142. of property rights and other protections to

  1143. women, banning polygamy, prohibiting the

  1144. burning alive of widows in India after their

  1145. husbands are deceased, outlawing the painful

  1146. and crippling practice of binding young

  1147. women's feet in China, persuading government

  1148. officials to begin a system of public schools in

  1149. Germany.

  1150. Two-thirds of the abolitionists in America in

  1151. the mid-1830s were Christian clergymen, not

  1152. just Christians, but clergymen.

  1153. In fact, English historian Tom Holland writes in

  1154. his book, Dominion, How the Christian Revolution

  1155. Remade the World, that every abolitionist movement

  1156. throughout all of human history, or at least the last

  1157. 2,000 years since Christ, from Gregory of Nyssa in the

  1158. fourth century to Martin Luther King Jr. in the

  1159. 20th century, every single one of them has been

  1160. Christian movements.

  1161. But I do want to add one qualifier here.

  1162. This doesn't mean that it is the mission of the church

  1163. as a whole or the church as an institution to specialize in

  1164. these public good works.

  1165. It's the church's mission to proclaim the gospel and make

  1166. disciples of Jesus Christ who will then obey everything

  1167. Christ has commanded them, including doing all these good

  1168. works.

  1169. It's not our mission as a church to build orphanages, but it

  1170. is our mission to produce disciples like George Mueller,

  1171. who built many orphanages and cared for 10,024 orphans during

  1172. his lifetime.

  1173. That's what Christian disciples do when they are rightly

  1174. discipled and they shine as light in the world.

  1175. It is not the mission of the church to collectively stage

  1176. protests and lobby lawmakers.

  1177. But it is our mission to produce disciples like William

  1178. Wilberforce, who led the charge in the UK of abolishing slavery.

  1179. I pray and hope and I trust that some of you will be

  1180. professors and scientists and lawyers and judges and

  1181. diplomats and legislators and teachers and financial

  1182. advisors and nurses and doctors who will make all kinds of

  1183. difference in the world.

  1184. But if the church as an institution, the collective church's

  1185. mission becomes merely the betterment of society, then we

  1186. will eventually lose sight of the gospel, which is the driving

  1187. engine of all our good works.

  1188. That's why he says in Philippians 2, 14 to 16, Paul tells us the

  1189. secret to shining as lights in the world.

  1190. And this is what he says.

  1191. You shine as lights in the world.

  1192. How?

  1193. Holding fast to the word of life.

  1194. What is the word of life?

  1195. It is the gospel of Jesus Christ.

  1196. The good news of Jesus Christ.

  1197. When we gather together, that's what we're doing.

  1198. We're holding fast to the word of life.

  1199. Being renewed and transformed by the gospel of Jesus Christ.

  1200. Receiving God's mercy so that we become more merciful people.

  1201. Receiving God's forgiveness so that we become more forgiving

  1202. people.

  1203. Receiving God's generosity so that we become more generous

  1204. people.

  1205. We hold fast to the word of life when we gather together so that

  1206. when we are scattered, we shine as bright lights in the world.

  1207. There's one more question that this passage raises and I'll

  1208. close with this.

  1209. Jesus says in verse 16,

  1210. let your light shine before others so that they may see your

  1211. good works and give glory to your father who is in heaven.

  1212. Does this mean then we should do our good works in order to be

  1213. seen by people?

  1214. So they can see our good works and then glorify God?

  1215. Because that seems to contradict what Jesus says repeatedly in the

  1216. gospel of Matthew, including in the Sermon on the Mount in Matthew 6,

    Matthew 6:1–4

  1217. verse 1 to 4 when Jesus says,

  1218. beware of practicing your righteousness before other people in order to be seen

  1219. by them.

  1220. For then you will have no reward from your father who is in heaven.

  1221. When you give to the needy, do not let your left hand know.

  1222. Sorry, this is your left.

  1223. So left hand know what your right hand is doing so that you're giving may be in

  1224. secret.

  1225. And your father who sees in secret will reward you.

  1226. Jesus says this multiple times.

  1227. He says, don't pray and fast in a manner to be seen by others.

  1228. Don't announce it to the world when you do it.

  1229. In Matthew 23, 5, Jesus denounces the scribes and the Pharisees for precisely this

  1230. thing because they do all their deeds in order to be seen by others.

  1231. So are we supposed to do our good deeds to be seen by others or not?

  1232. I think virtue signaling is never for the Christian.

  1233. We should never announce our good deeds on social media in order to be seen by others

  1234. and praised by men.

  1235. You might have other purpose, other reasons for doing that, but it should not be for the

  1236. purpose of being seen by men and would be praised by them.

  1237. That is consistently denounced in scripture.

  1238. There are some good works, however, that simply cannot be hidden, at least not from the people

  1239. that you are doing good to.

  1240. He says in 1 Timothy 5, 25, good works are conspicuous.

  1241. And even those that are not cannot remain hidden.

  1242. Don't worry about broadcasting your good works.

  1243. If you do your good works in secret before the Father who alone sees in heaven above,

  1244. eventually things come to light.

  1245. Sometimes it comes to light after you die.

  1246. All the better.

  1247. Yeah.

  1248. Yeah.

  1249. I think what matters is your heart's disposition.

  1250. Why do we do the glory?

  1251. Let your light shine before others so that they may see your good works.

  1252. Is that the ultimate purpose?

  1253. Is that the reason why we let our shine light before others?

  1254. No, that's not.

  1255. Let your light shine before others so that they may see your good works and give glory to your

  1256. Father who is in heaven.

  1257. Again, that's the reason.

  1258. That's the purpose.

  1259. If we are doing good deeds before others to be seen by men so that they give glory to us,

  1260. then that's, our heart's not in the right place.

  1261. Our goal is to give glory to God the Father in heaven.

  1262. And this is important because sometimes the good works that we do are not going to be praised by people.

  1263. Right?

  1264. We just talked about it in the last beatitude and that context is important because it immediately precedes this.

  1265. Jesus said,

  1266. Blessed are those who are persecuted for righteousness' sake.

  1267. Jesus said,

  1268. If you do righteous deeds,

  1269. if you do good deeds and obedience to God,

  1270. that the world will hate us and that it will persecute us.

  1271. And if we are out to get the world's praise,

  1272. if we are out to be seen by people so that they would praise us and glorify us,

  1273. then we will not do the works that will gain us infamy

  1274. and revulsion and slander from the world.

  1275. Because there are many good works that are like that.

  1276. So then what does it mean that people will see our good works and give glory to the Father in heaven?

  1277. Of course, there is some common grace.

  1278. And there are good works that we do that the world will agree are good works.

  1279. They'll see that, oh, that is good.

  1280. And that will bring some glory to God the Father.

  1281. But even when they don't recognize them,

  1282. they revile us as evildoers,

  1283. eventually the good works that we do will elicit praise and glory from all the world

  1284. when Christ returns.

  1285. And that's what we see in 1 Peter 2, 12.

  1286. He says,

  1287. We should keep our conduct among the Gentiles honorable,

  1288. even when they speak against us as evildoers,

  1289. so that they will see our good deeds and glorify God on the day of visitation.

  1290. It's speaking of the return of Christ,

  1291. the final day of visitation.

  1292. Even if we are maligned here on earth because of the good works that we do,

  1293. even if we are persecuted on account of righteousness,

  1294. there will be a day when every knee will bow before Christ

  1295. and every tongue will confess that he is God.

  1296. There will be a day when all the good deeds that you have done,

  1297. they will not have been in vain and they will be seen

  1298. and they will result in redounding glory to God, our heavenly Father.

  1299. That's why.

  1300. That's why we persevere.

  1301. So let's hold fast to the good news

  1302. and shine our light and do good works.

  1303. Let's pray.

  1304. Heavenly Father,

  1305. we are so lost apart from you.

  1306. in utter blindness,

  1307. groping about in the darkness,

  1308. unable to help ourselves from our sin.

  1309. Lord, that's who you were.

  1310. God, thank you

  1311. that in Jesus the light of the gospel has dawned.

  1312. And thank you that you now call us

  1313. the salt of the earth,

  1314. the light of the world.

  1315. What a privilege

  1316. and honor.

  1317. Father, thank you.

  1318. Help us to wear it well.

  1319. Help us to represent you well.

  1320. all for your glory.

  1321. In Jesus' name we pray.

  1322. Amen.
