In the same way, “Abraham believed God, and God counted him as righteous because of his faith.”
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 declare the Gentiles to be righteous 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.
