Galatians 3:26-29 The Seed of Abraham: Sons of God in Christ (February 8, 2026 AM, Dr. Michael Grasso)

"In Galatians 3:26–29, the Apostle Paul brings his redemptive-historical argument to a glorious climax: all who believe in Jesus Christ are sons of God, united to Christ, and true heirs of the promises made to Abraham.

In this sermon, we explore how Paul moves from defending justification by faith to unfolding its breathtaking implications. The law, which once functioned as a tutor guarding God’s people until the coming of the promised Seed, has now fulfilled its role. Christ has come. Faith has come. And in Christ, believers are no longer slaves—but sons.

We consider the doctrine of adoption alongside justification, showing how God not only declares sinners righteous by faith, but also declares them his own children. Through union with Christ—the true Son of God—believers are clothed with Christ himself and share in all his privileges. Because Christ is the Seed of Abraham, all who belong to him are Abraham’s offspring and heirs according to promise.

Paul’s declaration that there is “neither Jew nor Greek, slave nor free, male nor female” is examined carefully, not as an erasing of God-given distinctions, but as a proclamation of gospel unity. Ethnicity, social status, and gender no longer determine access to God or standing in his family. All who are in Christ are one—coheirs of the same inheritance, members of the same body, united to the same Savior.

This passage reminds us that the promises given to Abraham find their fulfillment not in physical descent or law-keeping, but in Christ alone. And by faith, those promises now belong to you.

You are not a slave. You are not a debtor striving to earn what cannot be earned. You are a son. You are a daughter. You are Abraham’s seed in Christ—and an heir of everything God promised.
