Galatians: Paul's Letter of Christian Freedom

Paul's letter to the Galatians is the great charter of Christian freedom. Written to congregations being unsettled by teachers who insisted that Gentile believers must adopt the works of the Mosaic law—circumcision in particular—to be fully right with God, Paul answers with a single, thunderous theme: we are justified by grace through faith in Christ alone, apart from the works of the law. Every other doctrine in the letter branches from that cornerstone.

The Two Covenants Behind the Letter

To grasp Galatians, it helps to see the two covenants Paul keeps holding up against each other. The covenant with Abraham (Genesis 12) was unilateral: God alone declared, "This is what I will do," and Galatians 3:6–9 confirms that those who believe are counted as Abraham's offspring and share his blessing. The covenant given through Moses 430 years later was bilateral, framed in "if… then" language, and—crucially—was never given to save. As Paul writes, "if a law had been given that could make alive, then righteousness would indeed come through the law" Galatians 3:21. The law's office is to expose sin and drive us to a Savior. This distinction between law and gospel runs through every chapter, as developed in Joshua: Servant of the Lord - Lesson 1.

The Promised Offspring Is Christ

Paul's argument hinges on a careful reading of the Abrahamic promise. In Galatians 3:16, he points out that the promise was made "to Abraham and to his offspring"—singular, not plural—"that is, to one person, who is Christ." The whole storyline of Israel, including the preservation of the promised land through Joshua's conquest, was God safeguarding a people and a place for the coming of His Son. The land had a true Heir, and that Heir is Jesus, as drawn out in Joshua: Servant of the Lord - Lesson 6.

The Law as Disciplinarian, Christ as Redeemer

Before faith was revealed, Paul writes, we were "imprisoned and guarded under the law" until Christ came Galatians 3:23–24. The law functioned as a disciplinarian—good, holy, and useful for restraining evil and revealing sin, but never the source of life. Then "when the fullness of time had come, God sent his Son, born of a woman, born under the law, to redeem those who were under the law, so that we might receive adoption as children" Galatians 4:4–5. In one verse Paul confesses both the full divinity and full humanity of Christ: the eternal Son sent by the Father, born of a woman to fulfill the law's demands in our place, as unfolded in Galatians: Lesson 8.

Heirs, Not Slaves

The result of Christ's work is a stunning change of status. "So you are no longer a slave, but a child, and if a child then also an heir through God" Galatians 4:7. An heir does not earn the inheritance; he receives it by birth. Through baptism into Christ we are clothed with Him—"there is no longer Jew or Greek… for all of you are one in Christ Jesus" Galatians 3:26–29. Paul illustrates this with the allegory of Hagar and Sarah: Hagar represents the earthly Jerusalem, the law, the conditional promise; Sarah represents the Jerusalem above, the church born of the Spirit, free and eternal. We are children of promise, like Isaac.

"For Freedom Christ Has Set Us Free"

"For freedom Christ has set us free. Stand firm therefore, and do not submit again to a yoke of slavery" Galatians 5:1. This is not merely civil liberty; it is freedom from the wrath of God, lodged in the conscience, so that Christians no longer live in dread. To trade this freedom for law-keeping as a means of justification is to "fall from grace" Galatians 5:4—not a loss of social standing, as the modern idiom suggests, but a tragic exchange of the gospel for a yoke that cannot save. Yet Christian liberty is no license for self-indulgence: "through love become slaves to one another" Galatians 5:13–14. Knowing we are justified in Christ frees us to love who Christ has made us to be, and out of that confidence love for the neighbor flows naturally, a theme explored in Galatians: Lesson 9.

Walking by the Spirit

Christian life is a real wrestling match. The flesh and the Spirit war against each other Galatians 5:16–21, and no believer this side of heaven escapes the struggle. But where the Spirit dwells, He bears fruit: "love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control" Galatians 5:22–23. When we fall to temptation, we do not despair—we confess, repent, and return to the cross, where forgiveness is freely given. Our assurance is not measured by the strength of our faith but by the strength of our Savior, since even faith itself is God's gift. Paul closes the letter with a benediction that captures the whole: "May the grace of our Lord Jesus Christ be with your spirit, brothers and sisters. Amen" Galatians 6:18.
