For--omitted in the oldest manuscripts. The grand reason why they should be reconciled to God, namely, the great atonement in Christ provided by God, is stated without the "for" as being part of the message of reconciliation (Co2 5:19). he--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," Gal 3:13. for us--Greek, "in our behalf." Compare Joh 3:14, Christ being represented by the brazen serpent, the form, but not the substance, of the old serpent. At His death on the cross the sin-bearing for us was consummated. knew no sin--by personal experience (Joh 8:46) [ALFORD].

The innocent was punished voluntarily as if guilty, that the guilty might be gratuitously rewarded as if innocent (Pe1 2:24). "Such are…

The apostle proceeds in showing the reasons why they did not faint under their afflictions, namely, their expectation, desire, and assurance of happiness after death (Co2 5:1-5), and deduces an inference for the comfort of believers in their present state (Co2 5:6-8), and another to quicken them in their duty (Co2 5:9-11). Then he makes an apology for seeming to commend himself, and gives a good reason for his zeal and diligence (Co2 5:12-15), and mentions two things that are necessary in order to our living to Christ, regeneration and reconciliation (Co2 5:16 to the end).

5:21 Christ became the offering for our sin on the cross when he took sin’s penalty on himself and died a criminal’s death.
