Galatians 4:30 tells the Galatian believers to cast out the slave woman and her son, because the child born to a slave will not share the inheritance of the child born to a free woman. Paul is making a point about who belongs to God’s family: people are made heirs by promise and by the Spirit, not by their own efforts or their standing under the law. He is quoting the Old Testament story of Hagar and Sarah, and he applies it to a dispute that was splitting the churches in Galatia.
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.”

What Galatians 4:30 Means
The phrase “Throw out the servant and her son” comes from Genesis 21, where Sarah asks Abraham to send Hagar and Ishmael away. Paul is not calling anyone to cruelty. He is saying that the family line of promise cannot be built on the same footing as the family line of human effort. Hagar’s son was born in the ordinary way, while Isaac was born through God’s promise to Sarah.
The phrase “will not inherit with the son of the free woman” carries the main weight. An inheritance here means the blessings and standing promised to Abraham’s family. Paul’s point is that these blessings come through the child of promise, which means believers who trust in Christ share in them, while those who try to earn God’s favor through the law are looking to the wrong source.
The verse does not say that people outside the promise are beyond God’s love, and it does not say that Abraham’s other descendants lost all hope. It addresses who holds the inheritance and how that inheritance is received, which is by faith and not by bondage to rules.
The Context of Galatians 4:30
Paul wrote the letter to the churches of Galatia, a region in what is now central Turkey, and it was traditionally attributed to him with a date in the late 40s or 50s AD. Some of the believers there were being pressed to accept circumcision and the works of the Mosaic law as necessary for full membership in God’s people. Paul writes to defend the gospel of grace and to call them back to freedom in Christ.
The verses just before this one, in Galatians 4:27 to 29, bring in Isaiah 54 and then describe the present tension between the two children. Verse 31 follows immediately with the conclusion that believers are children of the free woman. Read in this setting, Galatians 4:30 is the hinge of a single argument, and it shows that the choice before the Galatians was really a choice between two kinds of family life with God.

Galatians 4:31
So then, brothers, we are not children of a servant, but of the free woman.
(WEB)
This verse follows directly and states the conclusion Paul draws from the story. It makes clear that believers are children of the free woman, which gives Galatians 4:30 its purpose. Reading the two together shows the full force of the argument about freedom and inheritance.
Romans 8:15
For you didn’t receive the spirit of bondage again to fear, but you received the Spirit of adoption, by whom we cry, “Abba! Father!”
(WEB)
Paul writes here that believers have not received a spirit of slavery leading back to fear, but the Spirit of adoption. This echoes the contrast in Galatians 4:30 between bondage and freedom, and it shows how the Spirit makes the believer part of God’s family.
A Short Prayer From Galatians 4:30
Father, thank you that you have made a way for us to belong to your family by your promise and not by our own striving. Where I have tried to earn your favor, I ask you to free me from that burden and help me rest in what Christ has done. Teach me to live as a child of the free woman, with confidence and gratitude. Amen.
