Consider the experience of Abraham; as the scripture says, "He believed God, and because of his faith God accepted him as righteous." 1
You should realize, then, that the real descendants of Abraham are the people who have faith. 2
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." 3
Abraham believed and was blessed; so all who believe are blessed as he was.
