Born of Water and the Spirit: Understanding the Kingdom of God

Jesus said to Nicodemus:

John 3:5 (NIV) — “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit.”

It is one of the most surprising things Jesus ever said. Nicodemus was a religious leader, a man who had spent his life studying the Law and keeping it carefully. Yet Jesus tells him plainly: none of that is enough. To enter the Kingdom of God, something must happen to a person — a birth, not just a belief.

To understand what Jesus meant, we need to answer three questions. What is the Kingdom of God? What does it mean to be born of the Spirit? And what does it mean to be born of water?

What Is the Kingdom of God?

When we hear the words Kingdom of God, we may think of a place somewhere in heaven. But the Bible presents the Kingdom as something much deeper. The Kingdom of God is about God’s rule and authority. It is about allowing God to be King in our lives and choosing to live according to His will.

When the Pharisees asked Jesus when the Kingdom of God was coming, He answered:

Luke 17:21 (NIV) — “nor will people say, ‘Here it is,’ or ‘There it is,’ because the kingdom of God is in your midst.”

Jesus was not saying that the Pharisees had the Kingdom living inside them. He was pointing to Himself. The King was standing right there among them. God’s Kingdom had come near because Jesus, the King, was in their midst.

Jesus also began His ministry with this message:

Mark 1:15 (NIV) — “The time has come. The kingdom of God has come near. Repent and believe the good news!”

The Kingdom calls us to turn toward God, trust Him, and allow Him to rule our lives.

This does not mean that we become perfect or never make mistakes. It means that we begin to let God shape the way we think, the choices we make, and the way we treat others. Instead of always asking, “What do I want?” we begin to ask, “What does God want?”

That is why Jesus said:

Matthew 6:33 (NIV) — “But seek first his kingdom and his righteousness, and all these things will be given to you as well.”

And it is why He taught His disciples to pray for it:

Matthew 6:10 (NIV) — “Your kingdom come, your will be done, on earth as it is in heaven.”

His will being done. That is what the Kingdom looks like wherever it takes root.

Paul gives us a simple picture of what this Kingdom looks like in daily life:

Romans 14:17 (NIV) — “For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit.”

The Kingdom, then, is not merely about a place we hope to reach someday. It is about living under God’s rule today, while looking forward to the day when His Kingdom will be fully revealed.

What Is the Spirit?

To understand what it means to be “born of the Spirit,” we first need to understand what the Bible means by the spirit.

From the very beginning, God set humanity apart from the rest of creation:

Genesis 1:26 (NIV) — “Then God said, ‘Let us make mankind in our image, in our likeness.'”

Genesis 1:27 (NIV) — “So God created mankind in his own image, in the image of God he created them; male and female he created them.”

Human beings were created in the image of God. We are not simply physical bodies driven by instincts and desires. There is a spiritual dimension to human life that sets us apart from the rest of creation.

Scripture also tells us something about God’s nature:

John 4:24 (NIV) — “God is spirit, and his worshipers must worship in the Spirit and in truth.”

God is spirit. And we were made in His image. So there is something in us that is more than body.

The Bible speaks of human beings in terms of body, soul, and spirit. Paul writes:

1 Thessalonians 5:23 (NIV) — “May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ.”

So when Jesus tells Nicodemus that a person must be “born of the Spirit,” He is talking about something deeper than physical birth.

John 3:6 (NIV) — “Flesh gives birth to flesh, but the Spirit gives birth to spirit.”

Flesh gives birth to flesh. That is our natural birth. But the Spirit gives birth to spirit. Jesus is describing a new kind of life — a life that comes from God rather than simply from human nature.

Paul explains the difference between the two:

Romans 8:5 (NIV) — “Those who live according to the flesh have their minds set on what the flesh desires.”

Romans 8:6 (NIV) — “The mind governed by the Spirit is life and peace.”

And this new life does not remain hidden. It begins to show itself in the way a person lives:

Romans 8:14 (NIV) — “For those who are led by the Spirit of God are the children of God.”

Paul describes the evidence of this work as the fruit of the Spirit:

Galatians 5:22-23 (NIV) — “The fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control.”

But the Spirit’s work is not something we can see or control.

Jesus explained this to Nicodemus using an example that would have been familiar to everyone. In Greek, the word for “spirit” (pneuma) can also mean “wind.”

John 3:8 (NIV) — “The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.”

You cannot see the wind itself. You see what it does — leaves moving, trees bending, or a sail being filled. In the same way, we cannot see the Spirit with our physical eyes. But we can see His work through what He produces in a person’s life.

That is why the fruit of the Spirit is so important. It is the visible evidence of an invisible work.

So when Jesus says that a person must be “born of the Spirit,” He is not giving Nicodemus a method to follow. He is describing something God does in a person’s life. We may not be able to fully explain how the new birth happens, but we can see what it produces — a changed heart, a changed way of thinking, and eventually a changed way of living.

What Does It Mean to Be Born of Water?

Jesus tells Nicodemus that a person must be “born of water and the Spirit” to enter the Kingdom of God (John 3:5). But what does He mean by “born of water“?

It is tempting to assume Jesus means physical birth. He follows verse 5 with, “Flesh gives birth to flesh, but the Spirit gives birth to spirit” (John 3:6). So it is natural to pair “water” with “flesh.”

But Jesus does not say that flesh gives birth to water. He says that flesh gives birth to flesh, while the Spirit gives birth to spirit. Verse 6 is therefore pointing us toward the difference between our natural life and the new life that comes from the Spirit.

So what does Jesus mean by “water”?

Throughout Scripture, water is often associated with cleansing. And there is an important connection in the Old Testament that helps us understand this. Through the prophet Ezekiel, God promised:

Ezekiel 36:25-27 (NIV) — “I will sprinkle clean water on you, and you will be clean… I will give you a new heart and put a new spirit in you… I will put my Spirit in you.”

The connection is striking. There is cleansing, a new heart, a new spirit, and God’s Spirit. This sounds very much like the new life Jesus is describing to Nicodemus.

Paul uses similar language when he writes:

Titus 3:5 (NIV) — “He saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit.”

Here again, washing, rebirth, and the work of the Holy Spirit are brought together. The emphasis is not on what we accomplish for God, but on what God does for us.

This also connects with John the Baptist’s ministry:

Matthew 3:11 (NIV) — “I baptize you with water for repentance.”

And Acts gives us another example:

Acts 22:16 (NIV) — “And now what are you waiting for? Get up, be baptized and wash your sins away, calling on his name.”

This is why some understand the “water” in John 3:5 as pointing to cleansing and repentance, while others understand it as referring directly to baptism. Others understand it as physical birth.

But when we look at the broader biblical picture, water being connected with cleansing fits naturally with the message Jesus is giving Nicodemus. The point is that entering God’s Kingdom requires more than our natural birth. We need to be cleansed and given new life by the Spirit.

From Adam to Christ: Why We Need a New Spirit

This raises a deeper question: why do we need to be born again? Why can’t our natural life simply be made good enough to enter God’s Kingdom?

Scripture traces sin back to one man, Adam, and shows how its effects spread to all humanity:

Romans 5:12 (NIV) — “Sin entered the world through one man, and death through sin, and in this way death came to all people.”

Adam’s sin changed the human story. Sin entered the world, and death followed. Every person is born into this broken human condition. We cannot restore ourselves to God simply by trying harder or becoming better people.

But Scripture also points us to another man — Jesus Christ.

He did not enter the world the way the rest of us do:

Matthew 1:18 (NIV) — “This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit.”

Jesus was born of the Spirit, not through the natural line of Adam.

Paul draws a direct contrast between Adam and Christ:

1 Corinthians 15:22 (NIV) — “For as in Adam all die, so in Christ all will be made alive.”

And later he writes:

1 Corinthians 15:45 (NIV) — “So it is written: ‘The first man Adam became a living being’; the last Adam, a life-giving spirit.”

Adam became a living being. Christ, the last Adam, gives life.

That is the important difference. Through Adam came sin and death. Through Christ comes the possibility of forgiveness, reconciliation with God, and new life.

Jesus Himself connects this new birth with the work of the Spirit. But notice that He speaks of both water and the Spirit. The water points to cleansing and repentance, while the Spirit gives the new life that comes from God. This is why Jesus told Nicodemus that a person must be “born of water and the Spirit” (John 3:5).

The message is not simply that we need to change our behaviour. Repentance and cleansing are necessary, but the new life itself comes from God. We cannot create that life within ourselves. We need the Spirit.

This does not mean that a person becomes a completely different physical being. Rather, God begins a new work in that person. The old way of living no longer has to define them. Through Christ, they can be forgiven, changed, and brought into a new relationship with God.

Paul describes this transformation as a new creation:

2 Corinthians 5:17 (NIV) — “Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!”

So the message from Adam to Christ is not simply that humanity fell and needs to try harder. It is that what was lost through Adam cannot be restored by human effort alone. We need cleansing from sin, and we need the new life that comes through Christ by the Spirit of God.

Adam brought death. Christ brings life.

Conclusion

To enter the Kingdom of God, a person cannot rely on their birth, their own effort, or simply what they know, no matter how sincere they may be.

Flesh gives birth to flesh. It cannot give us the new life that comes from the Spirit.

What we need is a new birth — cleansing from sin and new life through the Spirit, made possible through Jesus Christ. Repentance turns us back to God, but it is the Spirit who gives us the new life we cannot produce on our own.

Like the wind, this new birth cannot be fully explained or controlled. We cannot see the Spirit Himself, but we can see what He produces in a person’s life. Love, joy, peace, kindness, faithfulness, gentleness, and self-control become the evidence of an invisible work.

Through Christ, we are not left trapped in the condition we inherited from Adam. We can be forgiven, made new, and brought into a new relationship with God. We become children of God, alive in Christ, and citizens of His Kingdom — a Kingdom whose King we can already follow and live under today.
