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?

19. God was in Christ, reconciling—that is, God was BY Christ (in virtue of Christ's intervention) reconciling," &c. Was reconciling" implies the time when the act of reconciliation was being carried into effect (2Co 5:21), namely, when "God made Jesus, who knew no sin, to be sin for us." The compound of "was" and the participle "reconciling," instead of the imperfect (Greek), may also imply the continuous purpose of God, from before the foundation of the world, to reconcile man to Himself, whose fall was foreseen. The expression " IN Christ" for "by Christ" may be used to imply additionally that God was IN Christ (Joh 10:38; 14:10), and so by Christ (the God-man) was reconciling … The Greek for "by" or "through" Christ (the best manuscripts omit "Jesus"), 2Co 5:18, is different. "In" must mean here in the person of Christ. The Greek Katallasson implies "changing" or altering the judicial status from one of condemnation to one of justification. The atonement (at-one-ment), or reconciliation, is the removal of the bar to peace and acceptance with a holy God, which His righteousness interposed against our sin. The first step towards restoring peace between us and God was on God's side (Joh 3:16). The change therefore now to be effected must be on the part of offending man, God the offended One being already reconciled. It is man, not God, who now needs to be reconciled, and to lay aside his enmity against God (Ro 5:10, 11). ("We have received the atonement" [Greek, reconciliation], cannot mean "We have received the laying aside of our own enmity"). Compare Ro 3:24, 25.

the world—all men (Col 1:20; 1Jo 2:2). The manner of the reconciling is by His "not imputing to men their trespasses," but imputing them to Christ the Sin-bearer. There is no incongruity that a father should be offended with that son whom he loveth, and at that time offended with him when he loveth him. So, though God loved men whom He created, yet He was offended with them when they sinned, and gave His Son to suffer for them, that through that Son's obedience He might be reconciled to them (reconcile them to Himself, that is, restore them WITH JUSTICE to His favor) [Bishop Pearson, Exposition of the Creed].
