The Scriptures say that God accepted Abraham because Abraham had faith. And so, you should understand that everyone who has faith is a child of Abraham. Long ago the Scriptures said that God would accept the Gentiles because of their faith. That's why God told Abraham the good news that all nations would be blessed because of him.
This means that everyone who has faith will share in the blessings that were given to Abraham because of his faith. Anyone who tries to please God by obeying the Law is under a curse. The Scriptures say, "Everyone who doesn't obey everything in the Law is under a curse."
Galatians 3:6-10 CEV
