Galatians 4 is Paul’s argument that believers are no longer slaves but adopted children and heirs of God through Christ. Readers look up this chapter to understand the contrast between slavery and sonship, why Paul calls the Galatians back from returning to religious rules, and how the story of Hagar and Sarah applies to Christian faith. The chapter moves from an analogy about heirs, to the sending of God’s Son and the Spirit, to a pastoral appeal, and finally to an allegory about two covenants.
Galatians 4 Summary
Paul begins with an everyday picture. A young heir, though he owns the whole estate, is managed by guardians and stewards until the appointed time of his father. Paul says that before Christ, we were in a similar position, held under the basic patterns of the world. Then comes the turning point: when the right time arrived, God sent his Son, born under the law, so that those under the law could be adopted as children and receive the Spirit who cries out to God as Father.
From there Paul shifts into a personal appeal. He is startled that the Galatians are turning back toward observing days, months, seasons, and years, as if these rules could add to what they already have in Christ. He reminds them of how warmly they once received him, and asks whether telling them the truth has made him their enemy. He describes his ongoing anxiety for them with the image of labor pains, longing for Christ to be formed in them.
The chapter closes with a story drawn from the Old Testament. Abraham had two sons, one from the enslaved woman Hagar and one from the free woman Sarah. Paul reads these women as two covenants, one leading to slavery and one leading to freedom. He ends by declaring that believers are children of the free woman, not children of the slave.
Background and Setting
Galatians is a letter traditionally attributed to the apostle Paul and is usually dated to the late 40s or 50s of the first century. It was written to churches in the region of Galatia, which were made up of both Jewish and Gentile believers who were being pressed to adopt circumcision and other aspects of the Mosaic law. Scholars debate the exact location and date of the recipients, but the letter’s central concern is clear: whether Gentile believers must keep the law to belong to God’s people.
Chapter 4 sits in the middle of the letter’s argument. Chapters 1 and 2 defend Paul’s apostolic authority and his gospel, and chapter 3 makes the case from Abraham’s faith that righteousness comes through promise. Chapter 4 turns that argument into the language of family, inheritance, and adoption, and chapter 5 moves on to the practical call to live free in the Spirit.
Galatians 4 Section by Section
Verses 1-7: From Slavery to Sonship
4 But when the fullness of the time came, God sent out his Son, born to a woman, born under the law, 5 that he might redeem those who were under the law, that we might receive the adoption of children.
Galatians 4:4-5 (WEB)
Paul uses the image of a child heir to show that the time before Christ was like childhood under guardians. Even though the heir owns everything, he is not yet free to act as an adult, and Paul says we were in a similar state under the basic principles of the world. The turning point is the sending of God’s Son, who was born under the law in order to redeem those held under it. Redemption here means buying back, the language of freeing a slave.
Paul’s point is that adoption is God’s gift, not a reward for passing a test. The Spirit cries out “Abba, Father” in believers’ hearts, which shows that they are truly God’s children and not merely servants. The chapter ends this section by stating the result plainly: you are no longer a slave but a son, and therefore an heir.
Verses 8-11: The Danger of Going Back
9 But now that you have come to know God, or rather to be known by God, why do you turn back again to the weak and miserable elemental principles, to which you desire to be in bondage all over again? 10 You observe days, months, seasons, and years.
Galatians 4:9-10 (WEB)
Paul now turns to the Galatians’ present danger. They once served beings that were not truly gods, but now they know God, or rather they have been known by God. Paul is surprised that they would turn back to the weak and useless principles that once held them. The observance of days, months, seasons, and years points to religious calendars that were being added to faith in Christ.
Paul is not condemning all attention to time in every setting. His concern is that these practices were being treated as a requirement for a relationship with God that had already been secured through grace. When people think they must add observances to earn what God has freely given, they lose the freedom Christ won.
Verses 12-20: A Father’s Heart
12 I beg you, brothers, become as I am, for I also have become as you are. You did me no wrong, 13 but you know that because of weakness in the flesh I preached the Good News to you the first time.
Galatians 4:12-13 (WEB)
Here Paul speaks as a pastor who loves the Galatians. He begs them to become like him, free from the law, since he has also become like them in living among Gentiles. He reminds them that they once received him warmly, even when his preaching came through physical weakness, and that they would have given him their own eyes if they could. That memory makes his current correction painful, and he asks whether telling the truth has made him their enemy.
Paul also contrasts the motives of those who are courting the Galatians. Their zeal is directed toward winning them over for themselves, not toward their good. Paul’s own longing is that Christ be formed in them, and he describes his labor with the image of birth pains that continue until that happens.
Verses 21-27: Two Covenants and Two Mothers
22 For it is written that Abraham had two sons, one by the servant, and one by the free woman. 23 However, the son by the servant was born according to the flesh, but the son by the free woman was born through promise. 24 These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar.
Galatians 4:22-24 (WEB)
Paul invites those who want to be under the law to hear what the law itself says. He turns to the story of Abraham and his two sons. One was born from the slave woman Hagar in the ordinary course of human planning, and the other was born from Sarah, the free woman, through the promise of God. Paul says these events carry an allegory, meaning they point to a deeper spiritual reality.
He identifies Hagar with the covenant from Mount Sinai, which produces children for slavery, and identifies the Jerusalem of his day with that same bondage. The Jerusalem above, by contrast, is free and is the mother of all believers. Paul supports this with a quotation from Isaiah celebrating the barren woman who will have more children than the one with a husband.
Verses 28-31: Children of Promise
28 Now we, brothers, as Isaac was, are children of promise. 29 But as then, he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. 30 However what does the Scripture say? “Throw out the servant and her son, for the son of the servant will not inherit with the son of the free woman.” 31 So then, brothers, we are not children of a servant, but of the free woman.
Galatians 4:28-31 (WEB)
Paul applies the story to the Galatians directly. Like Isaac, they are children of promise, not the product of human effort. Paul notes that the son born by the flesh persecuted the son born by the Spirit, and that this conflict continues in his own day. He then quotes Scripture’s command to cast out the slave woman and her son, concluding that believers are not children of a slave but of the free woman.
Key Themes in Galatians 4
- Adoption: God does not leave us as servants but welcomes us into his family as children with full standing.
- Freedom: Christ redeems us from slavery to the law and to the basic patterns of the world.
- The Spirit of Sonship: The Spirit gives believers the inward assurance to call God “Father.”
- Promise over effort: Like Isaac, believers are born through God’s promise rather than through human striving.
- Pastoral love: Paul’s firm correction flows from a heart that longs for the Galatians to be fully formed in Christ.
Lessons From Galatians 4 for Today
Many believers feel pressure to earn God’s approval through extra rules, routines, or achievements. Galatians 4 reminds you that adoption is already a finished gift, so your standing with God does not depend on how many boxes you check each week. You can still practice disciplines that help you grow, but they are responses to grace rather than payments toward it.
The chapter also speaks to friendships and church relationships. Paul was willing to say hard things because he loved the Galatians, and that honesty is still rare and valuable. If a trusted friend tells you something difficult about your faith or your choices, Paul’s example suggests that the words may come from someone who wants to see you grow, not someone who wants to be your enemy.

A Prayer From Galatians 4
Father, thank you that you did not leave me as a servant who must earn your love. Thank you for sending your Son to redeem me and for sending the Spirit into my heart to cry out to you as my Father. Where I have been tempted to trust my own efforts or rules, gently turn me back to the freedom you have already given. Give me the courage to receive truth from those who love me, and help me to grow into the likeness of Christ. Thank you that I am your child and your heir. Amen.
Frequently Asked Questions
What is the main point of Galatians 4?
Galatians 4 teaches that believers are adopted as God’s children through Christ and are no longer slaves to the law or the basic patterns of the world. Paul uses the example of an heir, the story of Abraham’s sons, and his own pastoral appeal to show why the Galatians should not return to religious observances as a means of earning God’s favor.
Who are Hagar and Sarah in Galatians 4?
Hagar and Sarah were the two women who bore Abraham’s sons, Ishmael and Isaac. Paul uses them as an allegory: Hagar represents the covenant from Mount Sinai that leads to bondage, and Sarah represents the freedom that comes through God’s promise. Believers are described as children of the free woman.
Why did Paul say the Galatians should not observe days and seasons?
Paul was concerned that the Galatians were treating calendar observances as necessary for a right relationship with God. He saw this as a return to the same kind of bondage they had escaped when they came to faith in Christ. His objection was to using these practices to add to grace, not to the practices themselves.
