Before the cross, before the Great Commission, Jesus had already spoken of this. In His conversation with Nicodemus — a Pharisee, a ruler of the Jews, a man who came to Jesus by night — Jesus said:
“Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.”
— John 3:3
Nicodemus was confused. He asked how a man could be born a second time. And Jesus answered:
“Truly, truly, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of God.”
— John 3:5
Born of water and the Spirit. Not one or the other. Both.
And here we have to stop and notice something most readers pass over. When Nicodemus still did not understand, Jesus did not soften His words or start over with a gentler illustration. He rebuked him:
“Are you the teacher of Israel and do not understand these things?”
— John 3:10
The rebuke is the interpretive key. Jesus was telling Nicodemus that the answer to what He had just said should not have been a mystery to any serious student of the Hebrew Scriptures. A Pharisee and a ruler of the Jews — a man whose life was built on the Law and the Prophets — should have heard “born of water and the Spirit” and known exactly where it came from.
And it comes, most clearly, from one chapter in the prophet Ezekiel.
“I Will Sprinkle Clean Water On You”
One chapter before the valley of dry bones, God spoke to Israel through Ezekiel in words that Nicodemus would have known by heart:
“Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols. Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances.”
— Ezekiel 36:25–27
Clean water. A new heart. A new spirit. God’s Spirit placed within. Read those verses slowly and then read John 3:5 again. Jesus was not inventing new material for Nicodemus. He was naming, in the barest possible terms, the promise Ezekiel had already recorded — the promise every Pharisee was waiting for. Water and Spirit. The cleansing God would do on the day He restored His people was a cleansing by water and the giving of His Spirit. Jesus told Nicodemus that day had come — and no one could enter the kingdom without passing through the door Ezekiel had described.
That is what Nicodemus should have seen. That is what the rebuke was about.
The Pattern God Had Always Used
And the chapter that follows — Ezekiel 37 — shows the same two forces at work on the largest possible canvas. God set the prophet down in a valley full of very dry bones and asked him whether they could live. Then He told Ezekiel what to do: first, “Prophesy over these bones, and say to them, ‘O dry bones, hear the word of the Lord’“ (Ezekiel 37:4). Ezekiel spoke. The bones came together. Sinews and flesh and skin. But there was still no life in them. Then God told him to prophesy again, this time to the breath — the Hebrew ruach, which means breath, wind, and Spirit all at once: “Come from the four winds, O breath, and breathe on these slain, that they come to life” (Ezekiel 37:9). Ezekiel prophesied. The breath came. They stood up, an exceedingly great army.
Two acts. The word, which gave structure. The breath, which gave life. The same pattern that ran all the way back to Genesis 2:7 — God formed the man from the dust of the ground, and then breathed into his nostrils the breath of life, and the man became a living being. Form and breath. Structure and Spirit. Dust and breath.
It is the same pattern Jesus named to Nicodemus. Water — literal water, received in the obedient response of faith — and the Spirit, God’s own life given to the one who obeys. Two aspects of one birth. And the Pharisee who knew Ezekiel by heart should have recognized it immediately.
Water Means Water
Faithful students of Scripture have read the “water” of John 3:5 in other ways — some as a figure for physical birth, others as a symbol for the word itself. We will not pretend the disagreement does not exist. But the reading most honest with the text is also the simplest: water means water.
When Scripture uses water figuratively, it says so. Jesus spoke of “living water” (John 4:10) and explained that He meant the Spirit (John 7:38–39). The text signals us when water stands for something else. But in John 3:5 there is no qualifier, no explanation, no figure flagged. Jesus says “born of water and the Spirit” — water and Spirit, distinct, named side by side — and then rebukes Nicodemus for not grasping what the Old Testament had already promised in those very terms. Ezekiel did not say God would sprinkle a metaphor on His people. He said God would sprinkle clean water.
And what Jesus named to Nicodemus, the apostles practiced everywhere they went. The answer they gave to every person who asked how to enter the kingdom was the same answer: repent, be baptized, receive the gift of the Holy Spirit (Acts 2:38). Water and Spirit, given to the one who obeyed the word — the same two components Jesus had named in the dark of that first conversation. Their preaching — and the response of every convert in the book of Acts — makes that understanding unmistakable.
Jesus had said there was no entry to the kingdom without it. Every apostolic sermon that followed took Him at His word.
