Commentary on Galatians 4
Overview
Galatians chapter 4 continues the argument from the preceding chapters, aiming to persuade the Galatian believers to abandon the observance of the Mosaic Law and fully obey the gospel. Specifically, the Apostle Paul addresses accusations that he himself had advocated for circumcision or taught it as a requirement for others. This was because false teachers had leveraged Paul's authority to compel the Galatians to practice circumcision (cf. Gal 5:11). This chapter contrasts the state of the Old Covenant under the Law with the freedom of the gospel enjoyed in Christ, explaining the true freedom and inheritance of God's children through the allegory of the heir and the slave, and the story of Hagar and Sarah.
Structure of the Text
Galatians chapter 4 can be broadly divided as follows:
Christians as Heirs and Those Under the Law as Slaves (4:1-7): Just as an heir, while a minor, is no different from a slave under guardians, believers under the Law, before the coming of Christ, did not fully enjoy freedom. However, through the Spirit of Christ sent to us, we have been adopted as sons of God, able to cry, "Abba, Father."
Rebuking the Return to Past Gentile Idolatry (4:8-11): Paul expresses surprise and concern that the Galatians, after coming to know God, are turning back to the weak and worthless elementary principles (the Law).
Paul's Personal Appeal and Relationship (4:12-20): Paul reminds the Galatians of how they welcomed him in the past, even when he was unwell, contrasting this with their current situation where they are being misled by others. He emphasizes the relationship they once had and earnestly desires for them to be formed into the image of Christ again.
The Allegory of Sarah and Hagar (4:21-31): Through this allegory, Paul clarifies that those who insist on the Law, even if they are Abraham's physical descendants, are not the children of promise. Only those born by faith, like Isaac born through Sarah, are the children of God. Hagar represents those born from Mount Sinai, symbolizing the present Jerusalem under the Law, who are slaves. Isaac, Sarah's son, symbolizes those born from above, who are free in Christ.Key Themes
Slavery Under the Law and Freedom in Christ (4:1-7, 21-31): The Law binds humanity under sin and death, akin to slavery. However, faith in Christ makes us children of God, granting us freedom and inheritance.
Sonship Through the Spirit (4:4-7): Through Christ's incarnation and atoning work, we have been adopted as sons of God. The indwelling Spirit grants us the privilege of calling God "Abba, Father."
The Contrast Between Gospel Truth and False Teaching (4:8-20): Paul rebukes the Galatians for departing from the truth of the gospel and being deceived by the false teaching of legalism, urging them to recover the true freedom of the gospel.
Inheritance by Faith (4:21-31): The allegory of Abraham's two sons, Ishmael and Isaac, clarifies that only those born by faith in the word of promise, not by physical lineage, are the true heirs of God.Exegetical Notes by Section
4:1-7 Christians as Heirs and Those Under the Law as Slaves
4:1-3: Paul uses the analogy of an heir who, while a minor, is no different from a slave under guardians. This explains that Old Testament saints under the Law, though children and heirs of God, were under the guardianship of the Law and thus could not fully enjoy freedom before Christ's coming. The Reformed tradition understands this as the 'mediatorial' function of the Law, emphasizing its role in leading to Christ. The Wesleyan/Methodist tradition highlights the new status and freedom enjoyed in Christ through this analogy.
4:4-5: "When the fullness of time had come," God sent his Son to redeem humanity and secure our adoption as sons. This marks the climax of God's redemptive plan. The Greek commentary emphasizes the mystery of the perfectly timed redemptive work through the phrase 'fullness of time' (πλήρωμα τοῦ χρόνου).
4:6-7: Because we are sons, God sent the Spirit of his Son into our hearts, crying, "Abba, Father." The Lutheran tradition emphasizes confident faith and God's grace through this cry. The Anglican tradition explains that the indwelling Spirit is the seal of our adoption as children of God.4:8-11 Rebuking the Return to Past Gentile Idolatry
4:8-9: Paul rebukes the Galatians for returning to the weak and worthless elementary principles (the rituals and regulations of the Law) after knowing God, having previously served non-existent gods. The Baptist tradition views this as revealing human sinfulness and warning against the danger of departing from true knowledge and faith.
4:10-11: Paul expresses deep concern about their observance of days, months, seasons, and years, indicating their falling into legalism. The Puritan tradition warns that such legalism can obscure the essence of the gospel and nullify the grace of Christ.4:12-20 Paul's Personal Appeal and Relationship
4:12: Paul urges the Galatians to become like him, a call to live in freedom under the gospel, abandoning the Law. The German Pietist tradition interprets this in the context of spiritual maturity and the importance of becoming like Christ.
4:13-16: Paul recalls how they welcomed him despite his physical infirmity, treating him as if he were Christ Jesus or an angel of God. This highlights the contrast between their former fervent faith when they received the gospel and their current state.
4:17-20: Paul criticizes those who mislead the Galatians for their own gain, pointing out that their zeal is not for a good purpose but to alienate the Galatians from him. He earnestly desires for them to be formed into the image of Christ again.4:21-31 The Allegory of Sarah and Hagar
4:21: Paul begins the allegory by asking if those who desire to be under the Law have not heard the Law.
4:22-23: Abraham had two sons: one by Hagar the slave woman, and the other by Sarah the free woman. Ishmael, born of Hagar, was born according to the flesh, while Isaac, born of Sarah, was born according to the promise.
4:24-27: This allegory symbolizes two covenants. Hagar represents the children born from Mount Sinai, symbolizing the present Jerusalem under the Law, belonging to the state of slavery. However, Isaac, born of Sarah, is the child of promise, symbolizing those born from above, free in Christ, belonging to the free woman. The Greek commentary emphasizes that this allegory has a spiritual meaning beyond mere historical events by using the term 'allegory' (ἀλληγορία).
4:28-31: The Galatians, like Isaac, are children of promise and should live freely as children of freedom, not as slaves under the Law like the children of Hagar. Paul uses the metaphor of 'casting out' for returning to legalism, urging them to firmly establish their identity as children of freedom.Original Language Insights

Identity as Those Born by Faith: We have become children of promise by God not through physical lineage or works, but solely through faith in Christ. We must clarify this identity and live as children of freedom.
Recover Past Fervor: Just as the Galatians lost the fervor they had when they first received the gospel, we must be vigilant not to lose our spiritual passion. Remembering our first love for Christ, we must restore our spiritual vitality.✨ SERMON SAGE
