Consider the experience of Abraham; as the scripture says, "He believed God, and because of his faith God accepted him as righteous." 17
You should realize, then, that the real descendants of Abraham are the people who have faith. 28
The scripture predicted that God would put the Gentiles right with himself through faith. And so the scripture announced the Good News to Abraham: "Through you God will bless all people." 39
Abraham believed and was blessed; so all who believe are blessed as he was.
