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, Co2 5:16. 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, Co2 5:17. 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, Co2 5:18, Co2 5:19. 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, Co2 5:18. 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, Co2 5:18. 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, Co2 5:20. 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 (Co2 5:21), 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.

Know we no man after the flesh - As we know that all have sinned and come short of the glory of God; and as we know that all are alienated from God, and are dead in trespasses and sins; therefore we esteem no man on account of his family relations, or the stock whence he proceeded, because we see all are shut up in unbelief, and all are children of wrath.

Yea, though we have known Christ after the flesh - We cannot esteem a man who is a sinner, were he even allied to the blood royal of David, and were he of the same family with the man Christ himself; nor can we prize a man because he has seen Christ in the flesh; for many have seen him in the flesh to whom he will say; Depart from me, for I never knew you. So we: nothing weighs with us, nor in the sight of God, but redemption from this death, and living to him who died for them.

We know that the Jews valued themselves much in having Abraham for their father; and some of the Judaizing teachers at Corinth might value themselves in having seen Christ in the flesh, which certainly St. Paul did not; hence he takes occasion to say here that this kind of privilege availed nothing; for the old creature, however noble, or well descended in the sight of men, is under the curse; and the new creature only is such as God can approve.

Therefore if any man be in Christ,.... There's a secret being in Christ from everlasting; so all that are loved by him, espoused unto him, chosen and preserved in him, to whom he was a covenant head, surety, and representative, are in him, united to him, and one with him; not in such sense as the Father is in him, and the human nature is in him, but as husband and wife, and head and members are one: and there is an open being in Christ at conversion, when a man believes in Christ, and gives up himself to him; faith does not put a man into Christ, but makes him appear to be in him: and such an one "is a new creature"; or, as some read it, "let him be a new creature": who understand being in Christ to be by profession, and the sense this, whoever is in the kingdom or church of Christ, who professes himself to be a Christian, ought to be a new creature: the Arabic version reads it, "he that is in the faith of Christ is a new creature". All such who are secretly in Christ from everlasting, though as yet some of them may not be new creatures, yet they shall be sooner or later; and those who are openly in him, or are converted persons, are actually so; they are a new "creation", as the words may be rendered: , "a new creation", is a phrase often used by the Jewish (h) doctors, and is applied by the apostle to converted persons; and designs not an outward reformation of life and manners, but an inward principle of grace, which is a creature, a creation work, and so not man's, but God's; and in which man is purely passive, as he was in his first creation; and this is a new creature, or a new man, in opposition to, and distinction from the old man, the corruption of nature; and because it is something anew implanted in the soul, which never was there before; it is not a working upon, and an improvement of the old principles of nature, but an implantation of new principles of grace and holiness; here is a new heart, and a new spirit, and in them new light and life, new affections and desires, new delights and joys; here are new eyes to see with, new ears to hear with, new feet to walk, and new hands to work and act with:

old things are passed away: the old course of living, the old way of serving God, whether among Jews or Gentiles; the old legal righteousness, old companions and acquaintance are dropped; and all external things, as riches, honours, learning, knowledge, former sentiments of religion, are relinquished:

behold, all things are become new; there is a new course of life, both of faith and holiness; a new way of serving God through Christ by the Spirit, and from principles of grace; a new, another, and better righteousness is received and embraced; new companions are sought after, and delighted in; new riches, honours, glory, a new Jerusalem, yea, new heavens, and a new earth, are expected by new creatures: or the sense of the whole may be this, if any man is entered into the kingdom of God, into the Gospel dispensation, into a Gospel church state, which seems to be the sense of the phrase "in Christ", in Gal 3:28 he is become a new creature, or is got into a new creation, as it were into a new world, whether he be a Jew or a Gentile; for with respect to the former state of either, "old things are passed away"; if a Jew, the whole Mosaic economy is abolished; the former covenant is waxen old, and vanished away; the old ordinances of circumcision and the passover are no more; the daily sacrifice is ceased, and all the other sacrifices are at an end, Christ, the great sacrifice, being offered up; the priesthood of Aaron is antiquated, there is a change of it, and of the whole law; the observance of holy, days, new moons and sabbaths, is over; the whole ceremonial law is at end; all the shadows of it are fled and gone, the things they were shadows of being come by Christ, the sum and substance of them; and there is no more a serving God in the oldness of the letter, but in the newness of the Spirit: and if a Gentile, all the former idols he worshipped he turns from, and his language is, "what have I to do any more with idols? or what agreement hath the temple of God with idols?" all former sacrifices, superstitious rites and ceremonies, with which he worshipped them, are relinquished by him; with all other Heathenish customs, rules, and methods of conduct he had been used to: "behold, all things are become new"; to the one, and to the other; the Gospel dispensation is a new state of things; a new form of church state is erected, not national, as among the Jews, but congregational, consisting of persons gathered out of the world, and anew embodied together; new ordinances are appointed, which were never in use before, as baptism and the Lord's supper; a new and living way is opened by the blood of Christ into the holiest of all, not by the means of slain beasts, as among the Jews, nor by petty deities as with the Gentiles; a new commandment of love is enjoined all the followers of the Lamb; and another name is given them, a new name, which the mouth of the Lord their God has named, not of Jews nor Gentiles, but of Christians; and new songs are put into their mouths, even praise to God: in short, the Gospel church state seems to be, as it were, a new creation, and perhaps is meant by the new heavens and new earth, Isa 65:15 as well as those who are the proper members of it, are new creatures in the sense before given.

Wherefore--because of our settled judgment (Co2 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 (Co2 11:18; Joh 8:15; Phi 3:4), as distinguished from what he is according to the Spirit, as a "new creature" (Co2 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 (Gal 2:6; Gal 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" (Gal 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 (Rom 6:9-11; Co1 15:45; Pe1 3:18; Pe1 4:1-2). Doubtless Judaizing Christians at Corinth prided themselves on the mere fleshly (Co2 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 (Co2 5:12; Co2 10:7). Paul here shows the true aim should be to know Him spiritually as new creatures (Co2 5:15, Co2 5:17), and that outward relations towards Him profit nothing (Luk 18:19-21; Joh 16:7, Joh 16:22; Phi 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.
