You are sons of the prophets, and of the covenant which God made with our fathers, saying to Abraham, 'And in your offspring all the families of the earth shall be blessed.'
Therefore it is of faith that it may be according to grace, so that the promise might be sure to all the seed, not only to those of the law, but also to those of the faith of Abraham, who is the father of us all,
Why then the law? It was added on account of transgressions, until the Seed should come to whom it had been promised; and it was commanded through angels by the hand of a mediator.
And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying that, "In you all the nations shall be blessed."
