Galatians 3:16-18

16In the same way, God promised to bless Abraham and Abraham's descendant. The Bible does not say ‘descendants’. It does not speak about ‘many people’. No, God promised to bless Abraham's descendant. He speaks about one person, and that person is Christ.

17What I mean is this: God made an agreement with Abraham. He promised to bless him. Then, 430 years later, God gave his Law to Moses for the Jewish people. But that Law could not take away the authority of God's agreement with Abraham. It could not stop what God had already promised.

18God has promised to give good things to his children. But that does not happen as a result of God's Law. If that were true, then we would not receive God's good things as a result of his promise. But God gave those good things to Abraham as a gift, because he had promised to bless Abraham.
