For he hath made him to be {q} sin for us, who {r} knew no sin; that we might be made the {s} righteousness of God in him.

(q) A sinner, not in himself, but by imputation of the guilt of all our sins to him.

(r) Who was completely void of sin.

(s) Righteous before God, and that with righteousness which is not fundamental in us, but being fundamental in Christ, God imputes it to us through faith.

People's New Testament

5:21 Hath made him to be sin for us, who knew no sin. As a sinless substitute he suffered for our sins,

that we might be made the righteousness of God in him. That our sins might thus be atoned for, the law satisfied, and we be forgiven and accounted righteous. Since we die with Christ, in him we pay the penalty, and are justified.

Wesley's Notes

5:21 He made him a sin offering, who knew no sin - A commendation peculiar to Christ. For us - Who knew no righteousness, who were inwardly and outwardly nothing but sin; who must have been consumed by the divine justice, had not this atonement been made for our sins. That we might be made the righteousness of God through him - Might through him be invested wi th that righteousness, first imputed to us, then implanted in us, which is in every sense the righteousness of God.

sin-not a sin offering, which would destroy the antithesis to "righteousness," and would make "sin" be used in different senses in the same sentence: not a sinful person, which would be untrue, and would require in the antithesis "righteous men," not "righteousness"; but "sin," that is, the representative Sin-bearer (vicariously) of the aggregate sin of all men past, present, and future. The sin of the world is one, therefore the singular, not the plural, is used; though its manifestations are manifold (Joh 1:29). "Behold the Lamb of God, that taketh away the SIN of the world." Compare "made a curse for us," Ga 3:13.

the righteousness of God-Not merely righteous, but righteousness itself; not merely righteousness, but the righteousness of God, because Christ is God, and what He is we are (1Jo 4:17), and He is "made of God unto us righteousness." As our sin is made over to Him, so His righteousness to us (in His having fulfilled all the righteousness of the law for us all, as our representative, Jer 23:6; 1Co 1:30). The innocent was punished voluntarily as if guilty, that the guilty might be gratuitously rewarded as if innocent (1Pe 2:24).

Matthew Henry's Concise Commentary

5:16-21 The renewed man acts upon new principles, by new rules, with new ends, and in new company. The believer is created anew; his heart is not merely set right, but a new heart is given him. He is the workmanship of God, created in Christ Jesus unto good works. Though the same as a man, he is changed in his character and conduct. These words must and do mean more than an outward reformation. The man who formerly saw no beauty in the Saviour that he should desire him, now loves him above all things. The heart of the unregenerate is filled with enmity against God, and God is justly offended with him. Yet there may be reconciliation. Our offended God has reconciled us to himself by Jesus Christ. By the inspiration of God, the Scriptures were written, which are the word of reconciliation; showing that peace has been made by the cross, and how we may be interested therein. Though God cannot lose by the quarrel, nor gain by the peace, yet he beseeches sinners to lay aside their enmity, and accept the salvation he offers. Christ knew no sin. He was made Sin; not a sinner, but Sin, a Sin-offering, a Sacrifice for sin. The end and design of all this was, that we might be made the righteousness of God in him, might be justified freely by the grace of God through the redemption which is in Christ Jesus. Can any lose, labour, or suffer too much for Him, who gave his beloved Son to be the Sacrifice for their sins, that they might be made the righteousness of God in him?

Matthew Henry's Whole Bible Commentary

Verses 16-21

In these verses the apostle mentions two things that are necessary in order to our living to Christ, both of which are the consequences of Christ's dying for us; namely, regeneration and reconciliation.

I. Regeneration, which consists of two things; namely, 1. Weanedness from the world: "Henceforth we know no man after the flesh, v. 16. We do not own nor affect any person or thing in this world for carnal ends and outward advantage: we are enabled, by divine grace, not to mind nor regard this world, nor the things of this world, but to live above it. The love of Christ is in our hearts, and the world is under our feet." Note, Good Christians must enjoy the comforts of this life, and their relations in this world, with a holy indifference. Yea, though we have known Christ after the flesh, yet, says the apostle, we know him no more. It is questioned whether Paul had seen Christ in the flesh. However, the rest of the apostles had, and so might some among those he was now writing to. However, he would not have them value themselves upon that account; for even the bodily presence of Christ is not to be desired nor doted upon by his disciples. We must live upon his spiritual presence, and the comfort it affords. Note, Those who make images of Christ, and use them in their worship, do not take the way that God has appointed for strengthening their faith and quickening their affections; for it is the will of God that we should not know Christ any more after the flesh. 2. A thorough change of the heart: For if any man be in Christ, if any man be a Christian indeed, and will approve himself such, he is, or he must be, a new creature, v. 17. Some read it, Let him be a new creature. This ought to be the care of all who profess the Christian faith, that they be new creatures; not only that they have a new name, and wear a new livery, but that they have a new heart and new nature. And so great is the change the grace of God makes in the soul, that, as it follows, old things are passed away-old thoughts, old principles, and old practices, are passed away; and all these things must become new. Note, Regenerating grace creates a new world in the soul; all things are new. The renewed man acts from new principles, by new rules, with new ends, and in new company.

II. Reconciliation, which is here spoken of under a double notion:-

1. As an unquestionable privilege, v. 18, 19. Reconciliation supposes a quarrel, or breach of friendship; and sin has made a breach, it has broken the friendship between God and man. The heart of the sinner is filled with enmity against God, and God is justly offended with the sinner. Yet, behold, there may be a reconciliation; the offended Majesty of heaven is willing to be reconciled. And observe, 1. He has appointed the Mediator of reconciliation. He has reconciled us to himself by Jesus Christ, v. 18. God is to be owned from first to last in the undertaking and performance of the Mediator. All things relating to our reconciliation by Jesus Christ are of God, who by the mediation of Jesus Christ has reconciled the world to himself, and put himself into a capacity of being actually reconciled to offenders, without any wrong or injury to his justice or holiness, and does not impute to men their trespasses, but recedes from the rigour of the first covenant, which was broken, and does not insist upon the advantage he might justly take against us for the breach of that covenant, but is willing to enter into a new treaty, and into a new covenant of grace, and, according to the tenour thereof, freely to forgive us all our sins, and justify freely by his grace all those who do believe. 2. He has appointed the ministry of reconciliation, v. 18. By the inspiration of God the scriptures were written, which contain the word of reconciliation, showing us that peace was made by the blood of the cross, that reconciliation is wrought, and directing us how we may be interested therein. And he has appointed the office of the ministry, which is a ministry of reconciliation: ministers are to open and proclaim to sinners the terms of mercy and reconciliation, and persuade them to comply therewith. For,

2. Reconciliation is here spoken of as our indispensable duty, v. 20. As God is willing to be reconciled to us, we ought to be reconciled to God. And it is the great end and design of the gospel, that word of reconciliation, to prevail upon sinners to lay aside their enmity against God. Faithful ministers are Christ's ambassadors, sent to treat with sinners on peace and reconciliation: they come in God's name, with his entreaties, and act in Christ's stead, doing the very thing he did when he was upon this earth, and what he wills to be done now that he is in heaven. Wonderful condescension! Though God can be no loser by the quarrel, nor gainer by the peace, yet by his ministers he beseeches sinners to lay aside their enmity, and accept of the terms he offers, that they would be reconciled to him, to all his attributes, to all his laws, and to all his providences, to believe in the Mediator, to accept the atonement, and comply with his gospel, in all the parts of it and in the whole design of it. And for our encouragement so to do the apostle subjoins what should be well known and duly considered by us (v. 21), namely, (1.) The purity of the Mediator: He knew no sin. (2.) The sacrifice he offered: He was made sin; not a sinner, but sin, that is, a sin-offering, a sacrifice for sin. (3.) The end and design of all this: that we might be made the righteousness of God in him, might be justified freely by the grace of God through the redemption which is in Christ Jesus. Note, [1.] As Christ, who knew no sin of his own, was made sin for us, so we, who have no righteousness of our own, are made the righteousness of God in him. [2.] Our reconciliation to God is only through Jesus Christ, and for the sake of his merit: on him therefore we must rely, and make mention of his righteousness and his only.
