Romans 3:26-30

To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.

Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.

Therefore we conclude that a man is justified by faith without the deeds of the law.

Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also:

Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
