New Birth

John 3:1–21

If someone collapses unexpectedly — no warning, no time to prepare — and their heart stops, the people around them don’t say, “Let’s give him some vitamins.” They don’t say, “He just needs to try harder.” They don’t suggest a self-help book.

They start CPR.

Because when someone is dead, encouragement doesn’t help. Advice doesn’t help. Improvement plans don’t help. Dead people don’t need inspiration. They need resurrection.

Spiritually speaking, that’s where the Bible says we are apart from Jesus. Not struggling. Not just confused. Not slightly off track…Dead in our sin.

There are moments in life when you realize that what you thought was enough… isn’t enough. You thought being a good person was enough. You thought going to church was enough. You thought knowing the right answers was enough.

But then you come face to face with Jesus… and He tells you something that shakes your foundation: “You must be born again.”

That’s what happens in John 3. A religious man. A respected leader. A teacher of Israel. And Jesus tells him he still lacks something essential.

Nicodemus thought people just needed better religion. Jesus told him something far more radical: “You must be born again.”

Not improved.

Not reformed.

Born again.

The greatest need in your life is not self-improvement — it’s new birth. Let’s walk through this conversation and see what it means for us.

You Must Be Born Again to See and Enter the Kingdom of God

John 3:1–8

John tells us that Nicodemus was a Pharisee, a ruler of the Jews. He wasn’t nonreligious. He wasn’t immoral. He wasn’t ignorant of Scripture. He was respected, disciplined and devout.

And yet Jesus tells him plainly: “Unless one is born again he cannot see the kingdom of God.” Not “try harder.” Not “clean yourself up.” Not “join the right group.”

You must be born again.

Nicodemus doesn’t get it. In Verse 4, he asks how this happen. He’s thinking physically. He hears “birth” and immediately thinks biology.

And that’s often how we respond too. We think external. We think behavior modification. We think religious activity.

But Jesus clarifies in verses 5–8:

“Unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.”

Jesus makes it clear — this is not about physical birth. It is about spiritual birth. You can improve the flesh. You can discipline the flesh. You can dress the flesh up in religion. But flesh is still flesh. It cannot produce spiritual life. Only the Spirit of God can do that.

Jesus compares it to the wind. You can’t see it. You can’t control it. But you can see the evidence of it. When the Spirit moves, something changes. This is the difference between religion and regeneration. Religion says, “Do better.” Jesus says, “Be made new.”

You don’t enter the kingdom by reforming your old life. You enter by receiving new life.

The Son of God Brings Eternal Life to Those Who Believe

John 3:9–15

Nicodemus is still confused “How can these things be?” Jesus responds almost with surprise. Nicodemus was a teacher of Israel. He knew the Scriptures. And yet he had missed the heart of them. It is possible to know Bible verses and not know spiritual life. Then Jesus shifts the conversation to Himself.

The Son of Man Must Be Lifted Up

Jesus says:

“As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life.”

He’s referencing Numbers 21:1–9. The Israelites had sinned. God sent fiery serpents among them. The people were dying. They cried out for mercy. And God instructed Moses to lift up a bronze serpent on a pole. Whoever looked at it in faith lived.

Numbers 21:1–9

But a few things to notice about Numbers 21:

• They were already bitten.

• They could not heal themselves.

• The cure required faith — simply looking at what God provided.

Jesus is saying: just as they looked and lived, you will look and live. We all have been bitten by sin. The poison is already in us. And we cannot cure ourselves. No amount of religion removes the venom. But the Son of Man would be lifted up — on a cross.

And whoever looks to Him in faith lives. Not because they deserve it. Not because they earned it. But because they believed.

God Loved and Sent

Then we come to the most well-known verse in the Bible — John 3:16.

John 3:16

John 3:16-21

John 3:16–21

“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.”

Notice the order.

God loved…God gave…We believe… We live. Salvation begins with God’s love, not our effort.

Verse 17 reminds us:

“For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.”

Jesus did not come primarily to judge — He came to save. But verses 18–21 explain something sobering. We are already under judgment because of our sin. The light has come into the world, but people love darkness rather than light. Judgment is not just about future punishment. It is revealed in what we love. Do we run to the light? Or do we hide in the dark?

Those born of the Spirit are drawn to the light. In order to see and enter the kingdom of God we must be born again.

What New Birth Means for Us

The new birth is not self-improvement. It is transformation. Jesus explains the necessity of new birth in John 3. Paul explains what that new birth looks like.

Romans 6:1–11

What shall we say, then? Shall we go on sinning so that grace may increase? 2 By no means! We are those who have died to sin; how can we live in it any longer? 3 Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? 4 We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life. 5 For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his. 6 For we know that our old self was crucified with him so that the body ruled by sin might be done away with, that we should no longer be slaves to sin—7 because anyone who has died has been set free from sin. 8 Now if we died with Christ, we believe that we will also live with him. 9 For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him. 10 The death he died, he died to sin once for all; but the life he lives, he lives to God. 11 In the same way, count yourselves dead to sin but alive to God in Christ Jesus.

Paul says that when, by faith, we meet Jesus in baptism, we are united with Jesus — joined to His death and resurrection. We are buried with Jesus. Our old self is crucified. You die to sin with Jesus in baptism. But Jesus doesn’t leave us dead. No we are also raised from the dead to live a new life. Not a self-improved life — but a transformed life. Shall we go on sinning so that grace may increase? No!

We trust that Jesus is all we need and are transformed by who He is and what He has done. Our old self is crucified with Jesus. So that sin is no longer our master. We are raised new with Jesus and He now is our master, our Lord and our savior.

Some of you have been born again — but you’re trying to live like you’re still dead. You’re fighting sin in your own strength. You’re living like slaves when you’ve been set free.

And in 2 Corinthians 5:17, he says:

2 Corinthians 5:17

“If anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.”

That’s new birth language. We have been reshaped. Remade. Re-created. We are not just forgiven sinners. We are new creations. We have a new beginning. A new identity.

Before Jesus, our identity was shaped by sin, shame, and striving. We were defined by what we had done, what had been done to us, or what we were trying to prove. The world tells us that we are identified by our desires, and attractions.

But the truth is our old ID: guilty, separated, spiritually dead — trying to earn what we could never achieve. And no amount of good behavior can change that old ID. Only new birth can.

But when we are born again, everything changes. As Paul says, we become a new creation. The old record is not cleaned up — it’s replaced.

Our new ID: forgiven, adopted, alive in Jesus, a child of God. We no longer stand before God based on our performance but on Jesus Christ’s finished work. The old identity was rooted in sin and death; the new identity is rooted in Jesus and life. We don’t just act differently — we are different. A new identity. We are born again as children of God.

As children, we inherit eternal life and the kingdom of God — not because of our actions. Our actions only bring judgment and death.

Those rights were secured by the actions of the Son of God — the Light of the world — who was lifted up for us.

So let me ask you: Have you been born again?

Not: Do you attend church? Do you know Bible stories? Are you a good person?

But has the Spirit of God given you new life? Have you looked to the Son lifted up on the cross and believed? By faith in Jesus have your repented of your sins and died to sin, meeting Jesus in baptism, being raised new.

The same invitation given to Nicodemus is given to us: You must be born again. And the promise still stands: Whoever believes in Jesus will not perish but have eternal life.

He came at night in chapter 3. But by chapter 19, he’s no longer hiding in the dark — he’s publicly identifying with a crucified Savior.

It seems the light eventually broke through. Maybe today, the light is breaking through for you. If the Spirit is stirring your heart right now — that’s not an accident. Stop trying to fix the old life. Receive the new one. Look to the Son. Believe. Be born again.

Some of you this morning don’t need more information. You don’t need another sermon. You don’t need another Bible study.

You need new birth. You’ve believed. You’ve felt the stirring. You know the Spirit has been drawing you. The question is — will you respond?

When Jesus told Nicodemus, “You must be born again,” He wasn’t giving him a suggestion. He was giving him an invitation into life.

And Scripture tells us that when we place our faith in Jesus, repent of our sins, and are united with Him in baptism, we are buried with Jesus Christ and raised to walk in newness of life. The old self crucified. The new life begun.

Baptism is not a religious ritual. It is not joining a church. It is not checking a box.

It is your moment of surrender. It is where faith meets obedience. It is where death turns into life. It is where you publicly say, “I am not who I was. I now belong to Jesus.”

If today you know you need to be born again — don’t wait.

Don’t put it off. Don’t walk out the same way you walked in.

We have water ready. If you’re ready to repent, to trust Jesus fully, to die to sin and be raised new — come.

Come out of the darkness into the light. Come be buried with Jesus. So you are raised into new life.

To see and enter the Kingdom of God, you must be born again. And today can be the day you are.
