¹⁹ But God replied, “No—Sarah, your wife, will give birth to a son for you. You will name him Isaac,^[a] and I will confirm my covenant with him and his descendants as an everlasting covenant.

²⁸ Many of the people of Israel are now enemies of the Good News, and this benefits you Gentiles. Yet they are still the people he loves because he chose their ancestors Abraham, Isaac, and Jacob. ²⁹ For God’s gifts and his call can never be withdrawn.

⁴ I will cause your descendants to become as numerous as the stars of the sky, and I will give them all these lands. And through your descendants all the nations of the earth will be blessed.

¹⁸ And through your descendants all the nations of the earth will be blessed—all because you have obeyed me.”

³ I will bless those who bless you and curse those who treat you with contempt. All the families on earth will be blessed through you.”

¹⁶ God gave the promises to Abraham and his child.^[a] And notice that the Scripture doesn’t say “to his children,^[b]” as if it meant many descendants. Rather, it says “to his child”—and that, of course, means Christ. ¹⁷ This is what I am trying to say: The agreement God made with Abraham could not be canceled 430 years later when God gave the law to Moses. God would be breaking his promise.

¹⁴ Your descendants will be as numerous as the dust of the earth! They will spread out in all directions—to the west and the east, to the north and the south. And all the families of the earth will be blessed through you and your descendants.
