21 But now the righteousness of God has been manifested apart from law, although the law and the prophets bear witness to it, 22 the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction; 23 since all have sinned and fall short of the glory of God, 24 they are justified by his grace as a gift, through the redemption which is in Christ Jesus, 25 whom God put forward as an expiation 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; 26 it was to prove at the present time that he himself is righteous and that he justifies him who has faith in Jesus. 27 Then what becomes of our boasting? It is excluded. On what principle? On the principle of works? No, but on the principle of faith. 28 For we hold that a man is justified by faith apart from works of law. 29 Or is God the God of Jews only? Is he not the God of Gentiles also? Yes, of Gentiles also, 30 since God is one; and he will justify the circumcised on the ground of their faith and the uncircumcised through their faith. 31 Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.

(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.
Commentary on Romans 3:27-31
(Read Romans 3:27-31)
God will have the great work of the justification and salvation of sinners carried on from first to last, so as to shut out boasting. Now, if we were saved by our own works, boasting would not be excluded. But the way of justification by faith for ever shuts out boasting. Yet believers are not left to be lawless; faith is a law, it is a working grace, wherever it is in truth. By faith, not in this matter an act of obedience, or a good work, but forming the relation between Christ and the sinner, which renders it proper that the believer should be pardoned and justified for the sake of the Saviour, and that the unbeliever who is not thus united or related to him, should remain under condemnation. The law is still of use to convince us of what is past, and to direct us for the future. Though we cannot be saved by it as a covenant, yet we own and submit to it, as a rule in the hand of the Mediator.
