Verse-by-Verse Commentary
The Book of John
Chapter 3: You Must Be Born Again
A respected teacher comes to Jesus by night, and Jesus cuts straight to the heart: unless one is born again, he cannot see the kingdom of God. Not reformed, not merely religious, but born anew, of water and the Spirit. In this chapter Jesus unfolds the new birth, points to His own lifting up on the cross as Moses lifted the serpent, and speaks the best-loved verse in the Bible: For God so loved the world that He gave His only begotten Son. John 3 is the gospel of the new birth and the love that gives it.

Setting the Stage
Nicodemus by Night
Nicodemus was a Pharisee and a ruler of the Jews, a respected teacher. He came to Jesus by night, and Jesus met his religious sincerity with the necessity of a radical new birth.
Born Again
Jesus declares that no one can enter the kingdom without being born again, of water and the Spirit, a birth from above that only God can give.
Lifted Up to Save
Jesus points to His own lifting up, as Moses lifted the bronze serpent in the wilderness, so that whoever believes in Him may have eternal life.
New Life from Above
Salvation is not self-improvement but new birth. It flows from the love of God, who gave His Son so that all who believe would not perish but have everlasting life.
Of Water and the Spirit (John 3:3-5)
Jesus answers Nicodemus not with a lesson but with a necessity that overturns everything.
Born of Water and the Spirit
"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. 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. 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? 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. 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. Nicodemus answered and said unto him, How can these things be? Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things? And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: That whosoever believeth in him should not perish, but have eternal life."
Greek Study
"Born again," gennao anothen (γεννάω ἄνωθεν). The word anothen means both "again" and "from above." The new birth is a second birth, and it comes from above, from God; it is not something we produce in ourselves.
Explanation
To Nicodemus, a ruler confident in his religion, Jesus says the unsettling words, "Except a man be born again, he cannot see the kingdom of God" -- and then defines that new birth: "except a man be born of water and of the Spirit, he cannot enter into the kingdom of God." This is the heart of the Apostolic gospel: entrance into God's kingdom comes by a birth of water (baptism) and Spirit (receiving the Holy Ghost), exactly the pattern Peter preaches at Pentecost -- repent, be baptized, and receive the gift of the Spirit (Acts 2:38). Religion, morality, and heritage cannot enter a man into the kingdom; only a new birth from above can, and it is God's work, unpredictable as the wind.
Gospel Focus
Jesus lays down an absolute necessity: "unless one is born of water and the Spirit, he cannot enter the kingdom of God." Being religious, moral, or a teacher of Israel like Nicodemus is not enough; there must be a new birth. And Jesus describes it in two elements, "water and the Spirit." Read alongside the whole New Testament, this is the new birth the apostles proclaimed, entered through baptism in water and the receiving of the Holy Spirit, exactly the pattern Peter preached at Pentecost: "be baptized... and ye shall receive the gift of the Holy Ghost" (Acts 2:38). Paul calls it "the washing of regeneration and renewing of the Holy Ghost" (Titus 3:5). The new birth is not self-improvement; it is a work of God, giving new life from above through water and Spirit. No one enters the kingdom without it.
For God So Loved the World (John 3:14-16)
Jesus points to His cross and reveals the love that stands behind the whole gospel.
He Gave His Only Begotten Son
"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. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 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. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. After these things came Jesus and his disciples into the land of Judaea; and there he tarried with them, and baptized. And John also was baptizing in Aenon near to Salim, because there was much water there: and they came, and were baptized. For John was not yet cast into prison. Then there arose a question between some of John's disciples and the Jews about purifying. And they came unto John, and said unto him, Rabbi, he that was with thee beyond Jordan, to whom thou barest witness, behold, the same baptizeth, and all men come to him. John answered and said, A man can receive nothing, except it be given him from heaven. Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him. He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled. He must increase, but I must decrease. He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: he that cometh from heaven is above all. And what he hath seen and heard, that he testifieth; and no man receiveth his testimony. He that hath received his testimony hath set to his seal that God is true. For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him. The Father loveth the Son, and hath given all things into his hand."
Greek Study
Jesus interprets the cross through the brass serpent Moses lifted up: as the serpent was raised for the dying to look and live, "even so must the Son of man be lifted up." The verb hypsoo ("lifted up") carries a double sense John loves -- lifted on the cross and lifted into glory, for the crucifixion is the exaltation. Then comes monogenes -- "only begotten" -- meaning unique, one-of-a-kind, the Son like no other. "God so loved the world, that he gave his only begotten Son": the love of God is measured by the priceless, unique gift He gave.
Explanation
John 3:16 distills the whole gospel: the love of God as its source, the gift of the Son as its cost, faith as its channel, and everlasting life against perishing as its outcome. "God so loved the world" -- not a narrow few but the world -- "that he gave his only begotten Son." The giving is the cross, the serpent lifted up, where dying men need only look in faith and live. God sent the Son "not to condemn the world; but that the world through him might be saved" -- yet those who refuse the light are condemned already, for they "loved darkness rather than light." The gift is universal in offer; the life is received by all who believe.
Gospel Focus
First Jesus points to the cross: "As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up" (verse 14). Just as dying Israelites looked to the bronze serpent and lived (Numbers 21:9), so those perishing in sin look in faith to the crucified Christ and are saved. Then comes the best-loved verse in the Bible, the gospel in a sentence: "For God so loved the world that He gave His only begotten Son." Behind the whole plan of salvation is love, God's love for a lost world. He did not merely feel love; He "gave," and He gave His Son. And the offer is universal, "whoever believes in Him", and the stakes eternal, "should not perish but have everlasting life." Here is why we must be born again, and how: because God so loved, and gave, that all who look to His Son in faith would live forever.
Believe on the Son (John 3:36)
The chapter closes by pressing the decision that everything turns on.
He Who Believes Has Everlasting Life
"He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him."
Greek Study
The chapter ends on a stark either/or: "He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him." The word orge (wrath) is God's settled, righteous opposition to sin -- not a fit of temper but the just response of holiness to evil. Note the tenses: the believer "hath" (present) everlasting life now, while on the unbeliever the wrath "abideth" -- remains, continues resting. There is no neutral ground; every soul either possesses life in the Son or remains under the wrath sin deserves.
Explanation
John (or the Baptist, whose testimony closes the chapter) sets before every reader the two possible states of the human soul, and they turn entirely on the Son. To believe on Him is to have everlasting life as a present possession; to refuse Him is to remain, unmoved, under the wrath already resting on a sinful world. The issue is not whether God is loving -- He gave His only Son (v. 16) -- but whether one receives or rejects that gift. Salvation is not earned by degrees; it is the difference between having life and not seeing it, and the Son is the one dividing line.
Gospel Focus
The chapter that began with the necessity of new birth ends with the two possible destinies, and they turn on the Son. "He who believes in the Son has everlasting life", not merely will have, but has it now. To be joined to Christ by a faith that obeys is to possess eternal life already. But the alternative is sobering: "he who does not believe the Son shall not see life, but the wrath of God abides on him." There is no neutral ground. Notice the word "abides", the wrath already resting on a lost world remains on those who refuse the Son. The love of God gave His Son to rescue us from that wrath; to refuse the Son is to stay under it. This is why the gospel is urgent. Everlasting life is found in the Son, and it is offered now to whoever will believe and come.
Chapter 3 in Review
John 3 is the gospel of the new birth. To Nicodemus, a sincere religious teacher, Jesus declares that no one can enter the kingdom of God without being born again, of water and the Spirit, a birth from above that only God gives. He points to His own lifting up on the cross, as Moses lifted the serpent, so that whoever believes may live, and speaks the best-loved verse in Scripture: "For God so loved the world that He gave His only begotten Son." The chapter closes by pressing the decision: everlasting life for those who believe the Son, abiding wrath for those who refuse Him.
For the Apostolic reader, this chapter is foundational. Salvation is not reformation but new birth, entered through water and Spirit, exactly the pattern the apostles preached. That new life flows from the love of God, who gave His Son so the perishing could look and live. And everything turns on the Son: to believe on Him is to have eternal life now; to reject Him is to remain under wrath. You must be born again, God so loved that He made it possible, and the choice is set before every heart.
- No one enters the kingdom without the new birth, of water and the Spirit (Acts 2:38; Titus 3:5).
- The new birth is God's work from above, not human self-improvement.
- The gospel flows from love: God so loved that He gave His only begotten Son.
- Everything turns on the Son: believing brings everlasting life; refusing leaves wrath abiding.
Questions for Reflection
- Jesus told a religious man he must be born again. Have you experienced the new birth of water and Spirit?
- God "gave" His Son out of love. How does the cost of your salvation move you?
- Everlasting life is in the Son, offered now. Have you believed on Him and come?
