Romans 3:25-31

25God presented Christ as a sacrifice of atonement, The Greek for sacrifice of atonement refers to the atonement cover on the ark of the covenant (see Lev. 16:15,16). through the shedding of his blood—to be received by faith. He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished—

26he did it to demonstrate his righteousness at the present time, so as to be just and the one who justifies those who have faith in Jesus. 27Where, then, is boasting? It is excluded. Because of what law? The law that requires works? No, because of the law that requires faith. 28For we maintain that a person is justified by faith apart from the works of the law. 29Or is God the God of Jews only? Is he not the God of Gentiles too? Yes, of Gentiles too, 30since there is only one God, who will justify the circumcised by faith and the uncircumcised through that same faith. 31Do we, then, nullify the law by this faith? Not at all! Rather, we uphold the law.
