Jesus Christ IS Salvation

A Study in John 3:9–21

There’s a well-known book in leadership and business circles called Good to Great by Jim Collins. In it, Collins identifies one of the key habits of truly great organizations: the willingness to confront the brutal facts. He calls it sustainable success built on “courageous, data-driven honesty” — the ability to face painful realities without losing faith in the ultimate outcome.

He coined a phrase for it: the Stockdale Paradox, named after Admiral Jim Stockdale. The idea is holding two things at once — unwavering faith that things will ultimately be okay, and the discipline to look honestly at how bad things actually are right now.

Good leaders do this. Good friends do this. Good pastors do this.

It is, in fact, unkind not to speak certain truths. If someone you love is headed toward destruction, the kindest thing you can do is hold up the mirror — even if it makes them angry, even if it costs you.

There are certain “musts” in life. We must eat and drink to survive. If a plane is going down, you must put on the parachute. If the ship is sinking, you must get into the lifeboat.

Jesus had a “must” for Nicodemus — and for every one of us.

The Conversation That Changes Everything

In John 3, we find one of the most important conversations ever recorded, between a prominent religious leader named Nicodemus and Jesus Christ. Earlier in the chapter, Jesus dropped a statement that stopped Nicodemus in his tracks: “You must be born again.”

To enter the Kingdom of God, Jesus said, a person must be born from above — by the Spirit of God.

Nicodemus was understandably confused. And the rest of the conversation answers his question: How?

Here’s what the passage teaches us: Every person must be born again by believing that Jesus Christ Himself is salvation. Three truths from John 3:9–21 confirm this.

1. Jesus Christ- the Authority to Teach Salvation (vv. 9–13)

When Nicodemus asked “How can these things be?”, he wasn’t just confused — he was stumped. This man was a master of Israel, a scholar of the Law. And yet the new birth was foreign to him.

Jesus responded with something like gentle astonishment: “Are you a teacher of Israel, and you don’t know these things?”

Then He made His case for why He — and He alone — has the authority to speak on salvation.

First, He has seen what He speaks of. “We speak of what we know, and testify to what we have seen” (v. 11). Jesus doesn’t theorize about heaven. He testifies from experience.

Second, He came from heaven. “No one has ascended into heaven except He who descended from heaven” (v. 13). No religious leader, no philosopher, no prophet had come from where Jesus had been.

Third, He is the Son of Man. This is the phrase that should have made Nicodemus sit up straight. It comes directly from Daniel 7:13–14 — the vision of One like the Son of Man coming before the Ancient of Days, receiving an everlasting Kingdom.

“There was given him dominion, and glory, and a kingdom, that all people, nations, and languages should serve him: his dominion is an everlasting dominion, which shall not pass away.”

Jesus isn’t just claiming to be a teacher. He’s claiming to be the King of the very Kingdom He’s describing. Who has the right to say “you must be born again to enter My Kingdom”? The King of that Kingdom.

Application: Jesus has the authority. He created the world. He is the Redeemer of the world. He speaks from heaven and is bringing the Kingdom of heaven to earth. We ought to do what He says.

2. Jesus Christ- the Way of Salvation (vv. 14–17)

Having established His authority, Jesus now explains how salvation works — and He does it through a story Nicodemus knew well.

“As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up: that whoever believes in Him should not perish, but have eternal life.” (vv. 14–15)

In Numbers 21, the people of Israel sinned against God and were judged — venomous serpents came into the camp, and people were dying. God gave Moses a strange command: make a bronze serpent and lift it up on a pole. Anyone who was bitten — anyone already condemned to die — if they simply looked at that serpent in faith, they lived.

Jesus tells Nicodemus: That’s Me.

He would be lifted up — on a cross. And whoever looks to Him in faith would not perish, but have eternal life.

There was a thief on the cross next to Jesus who experienced this exact promise in real time. Condemned. Dying. No religious pedigree, no time to clean up his life. He simply turned to Jesus: “Lord, remember me when You come into Your Kingdom.” And Jesus said, “Today you will be with Me in paradise” (Luke 23:42–43).

This is how it works. Then comes the verse that summarizes the entire Gospel:

“For God so loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life.” (John 3:16)

The greatest Giver. The greatest Gift. For the greatest need.

And lest anyone think God sent Jesus to judge: “For God sent not His Son into the world to condemn the world; but that the world through Him might be saved” (v. 17).

Application: Jesus Christ was given for the whole world. What an offer — to those of us condemned and without hope. The wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord. Look to Him and live.

---

3. Jesus Christ- the Condemnation for Rejecting Salvation (vv. 18–21)

This is where it gets sobering.

“He that believeth on Him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.” (v. 18)

Go back to the serpents in the wilderness. The people were bitten. They were already as good as dead — the poison was in their veins. Their condemnation was already set. God provided the remedy. But the remedy only worked for those who believed and looked. If a man refused to look, he didn’t become condemned because he refused — he was already condemned. He simply stayed condemned.

This is the condition of mankind. We are already dead in trespasses and sins. We already stand before God under a death sentence (Romans 3:23; 6:23). Jesus did not come to bring condemnation — it was already here. He came to rescue us from it.

So why do people stay condemned? Jesus is clear:

“And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.” (v. 19)

People reject Christ not because they haven’t heard, but because they love their sin more than they love the light. The light of Christ exposes dark hearts and dark deeds, and people don’t want that exposure.

Verse 20 uses the word “doeth” — a present active participle. It describes someone who is actively, presently doing evil. The person breaking into a house at night ducks when the squad car drives by. They’re not looking for the light; the light is looking for them.

But the one who has turned — who is walking in repentance — they welcome the light. They have nothing to hide, because they’re not hiding. And ultimately, anything good they do they credit to God, knowing that it is His grace working through them.

Application: If you’re in the dark — hiding, concealing, avoiding exposure — the best thing that could happen to you is exactly the thing you’re afraid of: the light.

Repentance isn’t just feeling bad. It’s agreeing with God about your sin. It’s coming into the light, looking to Christ in faith, and letting Him do a good work in you so He can do a good work through you.

So Here’s the Question

God sent Jesus on a rescue mission to save an already condemned world. To deny this reality is to deny your only hope of rescue. To keep it to yourself is to deny others the opportunity to hear it.

Jesus did not come to condemn the world. He came to rescue a condemned world.

Are you in the light or the dark?

Have you been born again? Have you believed in the only begotten Son of God?

If not — look to Him. The Son of Man is lifted up. Whoever looks to Him in faith will not perish, but have everlasting life.

That’s the brutal fact — and the glorious offer — of the Gospel.

What is the most important conversation you have ever had?

I can think of a few that stand out in my own life. Back in Christmas 2005, I traveled to Boise, Idaho to meet my then-girlfriend’s family — a young woman named Megan Smith. A few months later, we were talking seriously about marriage, and I made a phone call to her father to ask for his blessing. He was surprised enough that he and Megan’s mom flew out so we could have that conversation in person. I remember sitting in a hotel room with Roger Smith while Megan and her mom went shopping. It was an important conversation. I’m glad I passed the interview.

Maybe you have a conversation like that in your own story — one that changed your relationships, your direction, or your life. Maybe it was with a mentor who gave you exactly the right advice at the right time.

But for those of us who follow Christ, there is one category of conversation that rises above all others: the conversation that helped us come to trust in Jesus as our Savior.

The Most Important Question

I cannot think of a more crucially important subject than what happens to a person after they die. Is there a heaven and hell? How does someone enter the Kingdom of God?

When you step back and look at the world’s religions, they really fall into only two categories:

• The religion of works — you are made right with God by doing enough good to outweigh your bad.
• The religion of faith — you are made right with God by the righteousness of another.

Starting in John 3, we encounter one of the most important conversations ever recorded in human history. It has been studied, preached, and wrestled with for centuries. Warren Wiersbe recounts a fascinating anecdote about Benjamin Franklin and the British preacher George Whitefield:

“I find that you grow more and more famous in the learned world,” Whitefield wrote to Franklin. “As you have made such progress in investigating the mysteries of electricity, I now humbly urge you to give diligent heed to the mystery of the new birth. It is a most important and interesting study and, when mastered, will richly repay you for your pains.”

Whitefield was exactly right. And the conversation in John 3 gets to the heart of that mystery.

Two questions form the core of what Jesus and Nicodemus discuss:

1. How does a person get into the Kingdom of God?
2. How does someone know they are going there?

How Does a Person Get Into the Kingdom of God?

The Context: A Nighttime Visit (John 3:1–2)

There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him. — John 3:1–2

Nicodemus was not just any religious leader. He was a Pharisee — part of a conservative, theologically orthodox Jewish class that held both religious and political authority in Israel. These were men who knew the Scriptures and took them seriously.

He came to Jesus at night, likely to avoid being seen. But notice what he says when he arrives. He calls Jesus “Rabbi” — a term of respect — and then makes what would have been a significant concession from someone in his position: “We know that thou art a teacher come from God.”

The “we” is striking. He’s not just speaking for himself. He seems to be speaking on behalf of his entire circle — the Pharisees. The miracles Jesus was performing were accomplishing exactly what they were meant to: they authenticated His authority.

And yet — as significant as this admission was — it was not enough. It may have felt like a great concession to Nicodemus, but it did not go far enough. God is the authority on how a person enters into relationship with Him, not man. To be a little bit off is to miss heaven entirely.

1. The Necessity of New Birth (v. 3)

Jesus cuts straight to the heart of the matter:

Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. — John 3:3

The phrase “born again” is rich in the original Greek. The word translated “again” (ἄνωθεν, anōthen) can also mean “from above.” So Jesus is simultaneously saying: you must be born a second time, and that second birth must come from above — from God Himself.

Jesus frames this truth with “Verily, verily” — a double “amen.” He is doubling down on the certainty of what He is about to say. We might put it this way: “You can take this to the bank.” And what He is banking everything on is this: without a new birth, no one will see the Kingdom of God.

2. The Agency of New Birth (v. 4–6)

Nicodemus responds the way any of us might:

Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother’s womb, and be born? — John 3:4

He is not being foolish — he is being honest. The idea is physically absurd, and he knows it. So what does Jesus mean?

Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. — John 3:5–6

Jesus is drawing a distinction between two kinds of birth. Being “born of water” refers to physical birth — every person who has ever drawn a breath has been born that way. But physical birth is only the beginning. A person must also be born spiritually, and that second birth is the work of the Holy Spirit.

The parallelism in verse 6 makes it plain: flesh produces flesh, but the Spirit produces spirit. If you have only been born physically, you are alive in body but dead in spirit.

This is confirmed elsewhere in Scripture:

In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory. — Ephesians 1:13–14

Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; Which he shed on us abundantly through Jesus Christ our Saviour. — Titus 3:5–6

We are saved by grace through faith. When we hear the Word of God, the Spirit draws us. When we respond in faith — repenting of sin and trusting in Christ — the Holy Spirit regenerates us and seals us until the day we enter into the Kingdom He has prepared.

3. The Visibility of New Birth (v. 7–10)

Jesus then offers an illustration to help Nicodemus understand how this works:

Marvel not that I said unto thee, Ye must be born again. The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit. — John 3:7–8

You cannot see the wind. But you can see what the wind does. You can hear it. You can watch branches bend and leaves shake. The wind’s effects are undeniable, even when the wind itself is invisible.

The same is true of the Spirit. We do not see regeneration happen in real time. We cannot take a photograph and determine from it whether someone is saved. But over time, the evidence of genuine new birth becomes visible — in relationships, in priorities, in stewardship, in the direction of a person’s life. The Spirit of God living within a person affects everything.

This is exactly what James describes:

Even so faith, if it hath not works, is dead, being alone. Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works. Thou believest that there is one God; thou doest well: the devils also believe, and tremble. — James 2:17–19

The effect does not make the cause — but it does indicate the cause. Works do not earn salvation. But genuine salvation produces transformation. It is not from the outside in; it is from the inside out.

Nicodemus answered and said unto him, How can these things be? And Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? — John 3:9–10

There are systems of religion that look impressive from the outside. There are people sincerely trying to do good. But if the Spirit has not moved — if there has been no genuine new birth — there is no eternal transformation. Religion will not get you there. Good works will not get you there. You must be born again.

How Does Someone Know They Are Going There?

The Spirit’s work is the evidence. Romans 8 ties it together beautifully:

For as many as are led by the Spirit of God, they are the sons of God. For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father. The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together. — Romans 8:14–17

The Spirit Himself bears witness with your spirit. The leaves shake. The branches bend. There is evidence of the Spirit of God at work in the life of someone who has been born from above.

A Final Word

If you have only been born physically, you will die in your sins — separated from God. If you have been born physically and spiritually, you will see the Kingdom of God.

If the Spirit is drawing you right now — convincing you of your need, convicting you of your sin — do not harden your heart.

For he is our God; and we are the people of his pasture, and the sheep of his hand. To day if ye will hear his voice, harden not your heart. — Psalm 95:7–8

The most crucial conversation you can ever have is the one where you come face to face with Jesus Christ and the question He puts to every person: Will you be born again?

This post is part of an ongoing series through the Gospel of John — “That Ye May Believe.”

There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: 2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him. (John 3:1-2)

In these first couple of verses, we see the context for one of the most incredible conversations that has ever been recorded. There are two subjects talking in this conversation. We’re introduced to the first one in verse 1. His name was Nicodemus.

We are told in the first verse that he was a man of the Pharisees and a ruler of the Jews. This guy’s peers were the Pharisees. The Pharisees were a religious class that were fairly conservative in their beliefs. They were orthodox, they loved the Old Testament, they loved the law, they thought that they were right, and they were very self-assured of that idea. In fact, they enjoyed not just religious, but political power. Though subjugated by the Romans at the time, they still were the predominant religious Jewish authority.

We see in verse 2 the second person named, Jesus Christ. This is who Nicodemus came to by night. Some have said that the reason for this is because it was harder to be discovered that he was going to see Jesus if he went by night.

Verse 2 gives something of an admission. Nicodemus was definitely someone who had a differing opinion from the common opinion of the Pharisees regarding who Jesus was. He calls Jesus “Rabbi,” which would have been a sign of respect for sure. He also seems to admit something, and he’s admitting it not just on behalf of himself, but on behalf of all the Pharisees. He says, “We know”—the “we” meaning he and his tribe, he and his constituents, he and his Pharisaical group. “Rabbi, we know that thou art a teacher come from God.” He says, “We know you’re from God.” How do we know that? He says, “For no man can do these miracles that thou doest, except God be with him. ”The signs that Jesus was doing, named over and over again even in the first couple chapters of John, were having the effect that Jesus intended them to have. You’ll know that someone has God’s blessing and authority at some level because they do the miracles. So Nicodemus really feels like he is conceding, no doubt, by meeting with Jesus and by admitting that he believed that Jesus was on God’s side.

Application

Of course, this was not enough, and we’ll see that through the rest of the conversation. It may have seemed like it was a big admission or a big concession, but it did not go far enough for this man Nicodemus to be right with God, to get to heaven. The rest of the conversation deals with the kingdom of God and heaven—how you get there.I think an application that we can see here is clear. It may feel like you’re doing enough to get to God or that you are on God’s side by being reilgious. The truth is Jesus is the one who determines how far is far enough in terms of getting to God. God is the authority on how you have a relationship with Him, not man. To be a little bit off is to miss heaven.

Discussion Question

Is what you believe about God in line with what God has said about Himself?​​​​​​​​​​​​​​​​

Have you ever been ashamed or embarrassed about considering Jesus Christ?

Notice how Jesus responded to a surge in popularity in response to his miracles.

(23) Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did. (24) But Jesus did not commit himself unto them, because he knew all men, (25) And needed not that any should testify of man: for he knew what was in man. (John 2:23-25)

What does Jesus think of popularity?

This text speaks of the response of the mob, the crowd, in Jerusalem to the miracles of Jesus.  There was an excitement and acceptance of Jesus based on the miracles that he did.  It was the popular thing to talk about and accept what he was doing, but Jesus did not want to be treated like a passing fad.  

Notice all the plural language talking about multiple people.  Many, they, them, all men, any.  Even the word “man” is used like we would use “mankind”.  It’s not that this didn’t manifest itself individually.  It’s that Jesus was not driven by popularity.  He didn’t want to be received only as the latest new thing.  He did not “commit himself” or place his trust in their acceptance of him.  Why?  “Because he knew all men”.  His hope for success was not based on the acceptance of the crowd.

These couple of verses flows thematically into John 3, where Nicodemus is coming by night admitting that the miracles of Jesus were making many realize that Jesus was from God.  This conversation that follows shows that Jesus knew what was in the heart of Nicodemus individually, as well as the crowd that had an opinion of him.

Thinking about how Jesus knows us.

Jesus knows our hearts.  This is a terrible and ferocious reality.  He knows every thought, motivation, and feeling that I have.  He knows everything about me, and died for me anyway.  He is the only hope for cleansing and leading my heart in righteousness.

Jesus wants genuine faith.  When it comes to our spiritual lives, we must not be swayed by the crowd.  We don’t follow Jesus more when its popular to do so than when it will lead to persecution.  The cultures of men ebb and flow, but individually we must be steadfast, unmoveable, always abounding in the work of the Lord.

We should be more concerned with what God thinks than what men think.  It matters what God thinks of us infinitely more than what man thinks of us.  We are eternal beings living forever somewhere.  We should live accordingly.

Questions for application

1. Is your heart where it needs to be when it comes to Jesus?
2. How are you tempted to go with the crowd?
