5:16 {9} Wherefore henceforth know we no man after the flesh: {10} yea, though we have known Christ after the flesh, yet now henceforth know we [him] no more.
(9) He shows what it is not to live to ourselves but to Christ, that is, to know no man according to the flesh. That is to say, to be conversant among men and yet not to care for those worldly and carnal things, as those do who have regard for a man's family, his country, form, glory, riches, and such like, in which men commonly dote and weary themselves.
(10) An amplification: This is, he says, so true, that we do not now think carnally of Christ himself, who has now left the world, and therefore he must be thought of spiritually by us.
5:16 Wherefore henceforth know we no man according the flesh. As all have died to live new lives for Christ, they are not Jews and Gentiles; Romans, Greeks or Scythians, but all are Christians, not to be known as belonging to the old fleshly races longer.
Though indeed, we have known Christ after the flesh. The Christ risen and sitting on the throne as our Lord is not in the flesh, and the Christ to whom the church adores is that risen Christ.
5:16 So that we from this time - That we knew the love of Christ. Know no one - Neither ourselves, nor you, neither the rest of the apostles, Gal 2:6, nor any other person. After the flesh - According to his former state, country, descent, nobility, riches, power, wisdom. We fear not the great. We regard not the rich or wise. We account not the least less than ourselves. We consider all, only in order to save all. Who is he that thus knows no one after the flesh? ln what land do these Christians live? Yea, if we have known even Christ after the flesh - So as to love him barely with a natural love, so as to glory in having conversed with him on earth, so as to expect only temporal benefits from him.
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?
