Romans 3:21-24, 27-31

But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: for all have sinned, and come short of the glory of God; being justified freely by his grace through the redemption that is in Christ 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. Do we then make void the law through faith? God forbid: yea, we establish the law.
