¹ What I am saying is that as long as an heir is underage, he is no different from a slave, although he owns the whole estate. ² The heir is subject to guardians and trustees until the time set by his father. ³ So also, when we were underage, we were in slavery under the elemental spiritual forces of the world. ⁴ But when the set time had fully come, God sent his Son, born of a woman, born under the law, ⁵ to redeem those under the law, that we might receive adoption to sonship. ⁶ Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba, Father.” ⁷ So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.

Paul’s Concern for the Galatians

⁸ Formerly, when you did not know God, you were slaves to those who by nature are not gods. ⁹ But now that you know God-or rather are known by God-how is it that you are turning back to those weak and miserable forces? Do you wish to be enslaved by them all over again? ¹⁰ You are observing special days and months and seasons and years! ¹¹ I fear for you, that somehow I have wasted my efforts on you.
¹² I plead with you, brothers and sisters, become like me, for I became like you. You did me no wrong. ¹³ As you know, it was because of an illness that I first preached the gospel to you, ¹⁴ and even though my illness was a trial to you, you did not treat me with contempt or scorn. Instead, you welcomed me as if I were an angel of God, as if I were Christ Jesus himself. ¹⁵ Where, then, is your blessing of me now? I can testify that, if you could have done so, you would have torn out your eyes and given them to me. ¹⁶ Have I now become your enemy by telling you the truth?
¹⁷ Those people are zealous to win you over, but for no good. What they want is to alienate you from us, so that you may have zeal for them. ¹⁸ It is fine to be zealous, provided the purpose is good, and to be so always, not just when I am with you. ¹⁹ My dear children, for whom I am again in the pains of childbirth until Christ is formed in you, ²⁰ how I wish I could be with you now and change my tone, because I am perplexed about you!

Hagar and Sarah

²¹ Tell me, you who want to be under the law, are you not aware of what the law says? ²² For it is written that Abraham had two sons, one by the slave woman and the other by the free woman. ²³ His son by the slave woman was born according to the flesh, but his son by the free woman was born as the result of a divine promise.
²⁴ These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. ²⁵ Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children. ²⁶ But the Jerusalem that is above is free, and she is our mother. ²⁷ For it is written:
“Be glad, barren woman,
you who never bore a child;
shout for joy and cry aloud,
you who were never in labor;
because more are the children of the desolate woman
than of her who has a husband.”
²⁸ Now you, brothers and sisters, like Isaac, are children of promise. ²⁹ At that time the son born according to the flesh persecuted the son born by the power of the Spirit. It is the same now. ³⁰ But what does Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.” ³¹ Therefore, brothers and sisters, we are not children of the slave woman, but of the free woman.
