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.
24. justified freely—without anything done on our part to deserve.
by his grace—His free love.
through the redemption that is in Christ Jesus—a most important clause; teaching us that though justification is quite gratuitous, it is not a mere fiat of the divine will, but based on a "Redemption," that is, "the payment of a Ransom," in Christ's death. That this is the sense of the word "redemption," when applied to Christ's death, will appear clear to any impartial student of the passages where it occurs.
