24 Yet God freely and graciously declares that we are righteous. He did this through Christ Jesus when he freed us from the penalty for our sins. 25 For God presented Jesus as the sacrifice for sin. People are made right with God when they believe that Jesus sacrificed his life, shedding his blood. This sacrifice shows that God was being fair when he held back and did not punish those who sinned in times past, 26 for he was looking ahead and including them in what he would do in this present time. God did this to demonstrate his righteousness, for he himself is fair and just, and he declares sinners to be right in his sight when they believe in Jesus.

Commentary on Romans 3:21-26
(Read Romans 3:21-26)
Must guilty man remain under wrath? Is the wound for ever incurable? No; blessed be God, there is another way laid open for us. This is the righteousness of God; righteousness of his ordaining, and providing, and accepting. It is by that faith which has Jesus Christ for its object; an anointed Saviour, so Jesus Christ signifies. Justifying faith respects Christ as a Saviour, in all his three anointed offices, as Prophet, Priest, and King; trusting in him, accepting him, and cleaving to him: in all these, Jews and Gentiles are alike welcome to God through Christ. There is no difference, his righteousness is upon all that believe; not only offered to them, but put upon them as a crown, as a robe. It is free grace, mere mercy; there is nothing in us to deserve such favours. It comes freely unto us, but Christ bought it, and paid the price. And faith has special regard to the blood of Christ, as that which made the atonement. God, in all this, declares his righteousness. It is plain that he hates sin, when nothing less than the blood of Christ would satisfy for it. And it would not agree with his justice to demand the debt, when the Surety has paid it, and he has accepted that payment in full satisfaction.
