²⁹ And if you belong to Christ, then you are Abraham’s offspring,^[a] heirs according to the promise.^(A)

⁶ that is, the gentiles have become fellow heirs, members of the same body, and sharers in the promise in Christ Jesus through the gospel.^(A)

⁷ and not all of Abraham’s children are his descendants, but “it is through Isaac that descendants shall be named for you.”^{(A) 8} This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as descendants.

²² For it is written that Abraham had two sons, one by an enslaved woman and the other by a free woman.^{(A) 23} One, the child of the enslaved woman, was born according to the flesh; the other, the child of the free woman, was born through the promise.^{(B) 24} Now this is an allegory: these women are two covenants. One woman, in fact, is Hagar, from Mount Sinai, bearing children for slavery. ²⁵ Now Hagar is Mount Sinai in Arabia^[a] and corresponds to the present Jerusalem, for she is in slavery with her children. ²⁶ But the other woman corresponds to the Jerusalem above; she is free, and she is our mother.^{(C) 27} For it is written,

²⁸ Now you,^[b] my brothers and sisters, are children of the promise, like Isaac. ²⁹ But just as at that time the child who was born according to the flesh persecuted the child who was born according to the Spirit, so it is now also.^{(E) 30} But what does the scripture say? “Drive out the enslaved woman and her child, for the child of the enslaved woman will not share the inheritance with the child of the free woman.”^{(F) 31} So then, brothers and sisters, we are children, not of an enslaved woman but of the free woman.

¹⁷ and if children, then heirs: heirs of God and joint heirs with Christ, if we in fact suffer with him so that we may also be glorified with him.^(A)
