Galatians 3:7-9, 26-29

The real children of Abraham, then, are those who put their faith in God. What’s more, the Scriptures looked forward to this time when God would make the Gentiles right in his sight because of their faith. God proclaimed this good news to Abraham long ago when he said, “All nations will be blessed through you.” So all who put their faith in Christ share the same blessing Abraham received because of his faith.

For you are all children of God through faith in Christ Jesus. And all who have been united with Christ in baptism have put on Christ, like putting on new clothes. There is no longer Jew or Gentile, slave or free, male and female. For you are all one in Christ Jesus. And now that you belong to Christ, you are the true children of Abraham. You are his heirs, and God’s promise to Abraham belongs to you.
