Thy Strong Word — Galatians 4:1–20: From Slaves to Sons

Paul speaks not as a distant theologian but as a spiritual father pleading with his children. In Christ, they are no longer slaves but sons, adopted by God and filled with the Spirit. So why go back? Paul’s love and anguish come through clearly as he longs to see Christ formed in them once again.

The Rev. Gem Gabriel, pastor of St. Peter in Norwalk, CT, joins the Rev. Dr. Phil Booe to study Galatians 4:1–20.

There’s urgency in Paul’s voice. No warm greetings. No slow build. Just a sharp rebuke: “I am astonished that you are so quickly deserting Him who called you.” The stakes are that high.

Galatians is Paul’s bold stand for the pure Gospel message: Christ crucified and risen, apart from works of the law. When freedom in Christ is threatened by legalism or confused with license, Paul doesn’t hold back. He calls the Church back to the cross, to the promise, and to the Spirit. In this series on Thy Strong Word, we walk verse by verse through one of the most foundational and explosive letters in the New Testament. The message is clear: You are justified by faith, not by what you do.

Thy Strong Word, hosted by Rev. Dr. Phil Booe, pastor of St. John Lutheran Church of Luverne, MN, reveals the light of our salvation in Christ through study of God’s Word, breaking our darkness with His redeeming light. Each weekday, two pastors fix our eyes on Jesus by considering Holy Scripture, verse by verse, in order to be strengthened in the Word and be equipped to faithfully serve in our daily vocations.

Galatians 4:1-20

Sons and Heirs

4 I mean that the heir, as long as he is a child, is no different from a slave,^[a] though he is the owner of everything, ²but he is under guardians and managers until the date set by his father. ³In the same way we also, when we were children, were enslaved to the elementary principles^[b] of the world. ⁴But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, ⁵to redeem those who were under the law, so that we might receive adoption as sons. ⁶And because you are sons, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” ⁷So you are no longer a slave, but a son, and if a son, then an heir through God.

Paul’s Concern for the Galatians

⁸Formerly, when you did not know God, you were enslaved to those that by nature are not gods. ⁹But now that you have come to know God, or rather to be known by God, how can you turn back again to the weak and worthless elementary principles of the world, whose slaves you want to be once more? ¹⁰You observe days and months and seasons and years! ¹¹I am afraid I may have labored over you in vain.

¹²Brothers,^[c] I entreat you, become as I am, for I also have become as you are. You did me no wrong. ¹³You know it was because of a bodily ailment that I preached the gospel to you at first, ¹⁴and though my condition was a trial to you, you did not scorn or despise me, but received me as an angel of God, as Christ Jesus. ¹⁵What then has become of your blessedness? For I testify to you that, if possible, you would have gouged out your eyes and given them to me. ¹⁶Have I then become your enemy by telling you the truth?^[d] ¹⁷They make much of you, but for no good purpose. They want to shut you out, that you may make much of them. ¹⁸It is always good to be made much of for a good purpose, and not only when I am present with you, ¹⁹my little children, for whom I am again in the anguish of childbirth until Christ is formed in you! ²⁰I wish I could be present with you now and change my tone, for I am perplexed about you.

Rev. Dr. Phil Booe

Native North Carolinian Rev. Dr. Phil Booe serves pastor of St. John Lutheran Church of Luverne, MN, and host of Thy Strong Word on KFUO Radio. His parishioners probably think he can’t teach Bible study without a mug of coffee in his hand, and he’ll always be happy to eat a plate of sushi. When he’s not shepherding his flock or teaching on the radio, you might find him watching bad movies from the 50s, 60s, and 70s, and especially binging RiffTrax and MST3K episodes. Some day he’d love to travel to the Lutheran homeland in Germany, but for now he spends time in Minnesota with his wife, son, daughter, and cat, and looks forward to Holy Week every year.
