4 They are the people of Israel, God’s chosen children. They have the glory of God and the agreements he made between himself and his people. God gave them the Law of Moses, the Temple worship, and his promises.
5 They are the descendants of our great fathers, and they are the earthly family of the Messiah, who is God over all things. Praise him forever! Amen.
6 I don’t mean that God failed to keep his promise to the Jewish people. But only some of the people of Israel are really God’s people.
7 And only some of Abraham’s descendants are true children of Abraham. This is what God said to Abraham: “Your true descendants will be those who come through Isaac.”
8 This means that not all of Abraham’s descendants are God’s true children. Abraham’s true children are those who become God’s children because of the promise he made to Abraham.
9 Here is what God said in that promise: “About this time next year I will come back, and Sarah will have a son.”
10 And that is not all. Rebecca also had sons, and they had the same father. He is our father Isaac.
