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?

16. Wherefore—because of our settled judgment (2Co 5:14),

henceforth—since our knowing Christ's constraining love in His death for us.

know we no man after the flesh—that is, according to his mere worldly and external relations (2Co 11:18; Joh 8:15; Php 3:4), as distinguished from what he is according to the Spirit, as a "new creature" (2Co 5:17). For instance, the outward distinctions of Jew or Gentile, rich or poor, slave or free, learned or unlearned, are lost sight of in the higher life of those who are dead in Christ's death, and alive with Him in the new life of His resurrection (Ga 2:6; 3:28).

yea, though—The oldest manuscripts read, "if even."

known Christ after the flesh—Paul when a Jew had looked for a temporal reigning, not a spiritual, Messiah. (He says "Christ," not Jesus: for he had not known personally Jesus in the days of His flesh, but he had looked for Christ or the Messiah). When once he was converted he no longer "conferred with flesh and blood" (Ga 1:16). He had this advantage over the Twelve, that as one born out of due time he had never known Christ save in His heavenly life. To the Twelve it was "expedient that Christ should go away" that the Comforter should come, and so they might know Christ in the higher spiritual aspect and in His new life-giving power, and not merely "after the flesh," in the carnal aspect of Him (Ro 6:9-11; 1Co 15:45; 1Pe 3:18; 4:1, 2). Doubtless Judaizing Christians at Corinth prided themselves on the mere fleshly (2Co 11:18) advantage of their belonging to Israel, the nation of Christ, or on their having seen Him in the flesh, and thence claimed superiority over others as having a nearer connection with Him (2Co 5:12; 2Co 10:7). Paul here shows the true aim should be to know Him spiritually as new creatures (2Co 5:15, 17), and that outward relations towards Him profit nothing (Lu 18:19-21; Joh 16:7, 22; Php 3:3-10). This is at variance with both Romish Mariolatry and transubstantiation. Two distinct Greek verbs are used here for "know"; the first ("know we no man") means "to be personally acquainted with"; the latter ("known Christ … know … more") is to recognize, or estimate. Paul's estimate of Christ, or the expected Messiah, was carnal, but is so now no more.
