Galatians 3:14-16

14Through Christ Jesus, God has blessed the Gentiles with the same blessing he promised to Abraham, so that we who are believers might receive the promised Holy Spirit through faith.

15Dear brothers and sisters, here’s an example from everyday life. Just as no one can set aside or amend an irrevocable agreement, so it is in this case.

16God gave the promises to Abraham and his child. And notice that the Scripture doesn’t say “to his children,” as if it meant many descendants. Rather, it says “to his child”—and that, of course, means Christ.
