²⁹ And ^(A)if you are Christ's, then you are Abraham's offspring, ^(B)heirs according to promise.

⁶ This mystery is^[a] that the Gentiles are ^(A)fellow heirs, ^(B)members of the same body, and ^(C)partakers of the promise in Christ Jesus through the gospel.

⁷ and not all are children of Abraham ^(A)because they are his offspring, but ^(B)“Through Isaac shall your offspring be named.” ⁸ This means that it is not the children of the flesh who are the children of God, but ^(C)the children of the promise are counted as offspring.

²² For it is written that Abraham had two sons, ^(A)one by a slave woman and ^(B)one by a free woman. ²³ But ^(C)the son of the slave was born according to the flesh, while ^(D)the son of the free woman was born through promise. ²⁴ Now this may be interpreted allegorically: these women are two ^(E)covenants. ^(F)One is from Mount Sinai, bearing children for slavery; she is Hagar. ²⁵ Now Hagar is Mount Sinai in Arabia;^[a] she corresponds to the present Jerusalem, for she is in slavery with her children. ²⁶ But ^(G)the Jerusalem above is free, and she is our mother. ²⁷ For it is written,

²⁸ Now you,^[b] brothers, ^(I)like Isaac, ^(J)are children of promise. ²⁹ But just as at that time he who was born according to the flesh ^(K)persecuted him who was born according to the Spirit, ^(L)so also it is now. ³⁰ But what does the Scripture say? ^(M)“Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.” ³¹ So, brothers, we are not children of the slave but ^(N)of the free woman.

⁷ Know then that it is ^(A)those of faith who are ^(B)the sons of Abraham.

¹⁶ That is why it depends on faith, ^(A)in order that the promise may rest on grace and ^(B)be guaranteed to all his offspring—not only to the adherent of the law but also to the one who shares the faith of Abraham, ^(C)who is the father of us all, ¹⁷ as it is written, ^(D)“I have made you the father of many nations”—in the presence of the God in whom he believed, ^(E)who gives life to the dead and calls into existence ^(F)the things that do not exist. ¹⁸ In hope he believed against hope, that he should become the father of many nations, as he had been told, ^(G)“So shall your offspring be.” ¹⁹ He did not weaken in faith when he considered his own body, which was ^(H)as good as dead (^(I)since he was about a hundred years old), or when he considered ^(J)the barrenness^[a] of Sarah's womb. ²⁰ No unbelief made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, ²¹ fully convinced that ^(K)God was able to do what he had promised.

¹⁷ and if children, then ^(A)heirs—heirs of God and fellow heirs with Christ, ^(B)provided we suffer with him in order that we may also be glorified with him.

⁷ so that ^(A)being justified by his grace we might become ^(B)heirs ^(C)according to the hope of eternal life.

⁷ So you are no longer a slave, but a son, and if a son, then ^(A)an heir through God.
