John 1:13 Commentary: Study: Born of God, Not of Human Will

First-century Judaism prized descent from Abraham. Matthew 3:9 records John the Baptist telling the Pharisees, “Don’t think to yourselves, ‘We have Abraham for our father,’ for I tell you that God is able to raise up children to Abraham from these stones.” John’s Gospel confronts that assumption directly. The phrase “not of blood” (plural “bloods”) likely echoes Jewish proselyte practice. Adam Clarke notes that Jews required circumcision, baptism, and sacrifice to convert a Gentile; the blood of circumcision and the blood of the Passover lamb were sometimes mingled in a rite thought to bring a proselyte into the covenant. By denying “bloods,” John insists that no ritual, no lineage, no ethnic privilege can produce a child of God.

The two “will” phrases also have a cultural background. “Will of the flesh” points to natural generation, the ordinary way children are born. Regeneration is not a second physical birth, as Nicodemus mistakenly thought (John 3:3-5). “Will of man” uses the Greek anēr, often meaning an adult male or husband. Some commentators see here a reference to human adoption in Roman culture, where a father could make a child his heir even without biological ties. John says no human decision, not even adoption by a pious man, can bring someone into God’s family. The only will that matters is God’s. This threefold denial would have sounded radical to Jewish ears that trusted in Abraham and to Gentile ears that valued social advancement. The new birth is not an upgrade to an existing status; it is a creation from scratch.

The consulted sources note one significant variant. Tertullian (c. AD 200) read “was born” (singular) referring to Christ, and accused the Valentinians of corrupting the text to “were born” (plural). The Cambridge Bible comments that the reading “were born” is “undoubtedly right,” noting that such early corruption shows the gospel was already circulating by AD 85-100. All other consulted sources accept the plural reading. No other significant textual variants are noted.

This verse has been a cornerstone of teaching on regeneration. In the early church, it was used against Pelagianism to affirm that salvation is God’s work from start to finish. Tertullian’s variant shows it was also drawn into Christological debates, with some trying to refer it to the incarnation of Christ, but the mainstream reading consistently referred to believers. The Reformers leaned on it heavily to argue against salvation by works or inherited church membership. In the Wesleyan tradition, it became a key text for the doctrine of the new birth (see Wesley’s explanatory note). Catholic theology has affirmed it in the context of baptismal regeneration, insisting that even in infant baptism, the new birth is God’s act, not human merit. Across traditions, the verse stands as a clear witness to grace: God’s children are born of God.

Three-point outline

1. Not inherited (not of blood), No family line, church membership, or religious ritual confers spiritual sonship. God’s children are not born into the family by natural descent.
2. Not achieved (not of the will of the flesh), No amount of human effort, moral striving, or fleshly desire produces the new birth. It is not a decision we can force.
3. Not conferred by another (not of the will of man), No pastor, parent, or mentor can make someone a child of God. Only God can.

Five-point outline

1. The privilege of sonship, Verse 12: those who receive Christ become children of God. This is the context for verse 13.
2. The exclusive source, The three denials close every human door. The new birth is “of God.”
3. The nature of the birth, The Greek verb is aorist passive: it is something done to us, not something we do. It is a birth, not a project.
4. The contrast with the world, The world values pedigree, effort, and power; God values his own work in the heart.
5. The call to humility, No one can boast. The ground is level at the cross. Every child of God shares the same origin: God’s will.

Illustration hooks

• Adoption day, A child in a courtroom does not choose to be adopted. The judge reads the decree, the papers are signed, and the child goes home. The new birth is like that, a decree from heaven that changes everything.
• A newborn baby, A baby does nothing to be born. It does not decide to take a breath. Birth happens to the baby. The new birth happens to the believer.
• Family resemblance, You cannot choose your biological parents. But in the new birth, you receive a family likeness that grows over time. The mark is not physical but spiritual.

Questions your congregation is asking

• “I was raised in a Christian home. Does that mean I am automatically saved?”
• “I have tried to be a better person, but I keep failing. Have I not been born again?”
• “Can I help someone else get born again, or is that only God’s work?”

John 1:13 strips away every human claim on God’s family. It forces us to ask: where is my confidence placed? In my background, my efforts, or in God alone? This passage is both a humbling and a liberating word. It humbles because we can take no credit; it liberates because the work does not depend on us.

Discussion questions

1. What does the phrase “not of blood” mean in the context of first-century Judaism? How does Matthew 3:9 help explain it?
2. The verse uses three denials before the positive statement. Why do you think John is so repetitive here? What effect does it have?
3. What is the difference between being a child of God as a title and actually being born of God? (See verse 12 for the title, verse 13 for the birth.)
4. In what ways do people today still think they can become God’s children through “blood” (family heritage), “will of the flesh” (self-improvement), or “will of man” (human approval)? Give examples.
5. How does the aorist passive verb “born” (an action done to the subject) shape our understanding of conversion?
6. This verse is a great comfort to those who feel disqualified. Who do you know that needs to hear that the new birth does not depend on their past?
7. If being born anew is entirely God’s work, then what role does human faith play? How do verses 12-13 together answer that?
