Romans 3:25-27 ESV
whom God put forward as a propitiation by his blood, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins. It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus.
Then what becomes of our boasting? It is excluded. By what kind of law? By a law of works? No, but by the law of faith.
