Romans 6:6

Our old man is crucified with him - This seems to be a farther extension of the same metaphor. When a seed is planted in the earth, it appears as if the whole body of it perished. All seeds, as they are commonly termed, are composed of two parts; the germ, which contains the rudiments of the future plant; and the lobes, or body of the seed, which by their decomposition in the ground, become the first nourishment to the extremely fine and delicate roots of the embryo plant, and support it till it is capable of deriving grosser nourishment from the common soil. The body dies that the germ may live. Parables cannot go on all fours; and in metaphors or figures, there is always some one (or more) remarkable property by which the doctrine intended is illustrated. To apply this to the purpose in hand: how is the principle of life which Jesus Christ has implanted in us to be brought into full effect, vigor, and usefulness? By the destruction of the body of sin, our old man, our wicked, corrupt, and fleshly self, is to be crucified; to be as truly slain as Christ was crucified; that our souls may as truly be raised from a death of sin to a life of righteousness, as the body of Christ was raised from the grave, and afterwards ascended to the right hand of God. But how does this part of the metaphor apply to Jesus Christ? Plainly and forcibly. Jesus Christ took on him a body; a body in the likeness of sinful flesh, Romans 8:3; and gave up that body to death; through which death alone an atonement was made for sin, and the way laid open for the vivifying Spirit, to have the fullest access to, and the most powerful operation in, the human heart. Here, the body of Christ dies that he may be a quickening Spirit to mankind. Our body of sin is destroyed by this quickening Spirit, that henceforth we should live unto Him who died and rose again. Thus the metaphor, in all its leading senses, is complete, and applies most forcibly to the subject in question. We find that παλαιος ανθρωπος, the old man, used here, and in Ephesians 4:22, and Colossians 3:9, is the same as the flesh with its affections and lusts, Galatians 5:24; and the body of the sins of the flesh, Colossians 2:11; and the very same which the Jewish writers term אדם הקדמוני, Adam hakkadmoni, the old Adam; and which they interpret by יצר הרע yetsar hara, "evil concupiscence," the same which we mean by indwelling sin, or the infection of our nature, in consequence of the fall. From all which we may learn that the design of God is to counterwork and destroy the very spirit and soul of sin, that we shall no longer serve it, δουλευειν, no longer be its slaves. Nor shall it any more be capable of performing its essential functions than a dead body can perform the functions of natural life.

Knowing this - We all knowing this. All Christians are supposed to know this. This is a new illustration drawn from the fact that by his crucifixion our corrupt nature has been crucified also, or put to death; and that thus we should be free from the servitude of sin.

Our old man - This expression occurs also in Ephesians 4:22, "That ye put off ...the old man which is corrupt according to the deceitful lusts." Colossians 3:9, "lie not to one another, seeing that ye have put off the old man with his deeds." From these passages it is evident that Paul uses the expression to denote our sinful and corrupt nature; the passions and evil propensities that exist before the heart is renewed. It refers to the love of sin, the indulgence of sinful propensities, in opposition to the new disposition which exists after the soul is converted, and which is called "the new man."

Is crucified - Is put to death, as if on a cross. In this expression there is a personification of the corrupt propensities of our nature represented as "our old man," our native disposition, etc. The figure is here carried out, and this old man, this corrupt nature, is represented as having been put to death in an agonizing and torturing manner. The pains of crucifixion were perhaps the most torturing of any that the human frame could bear. Death in this manner was most lingering and distressing. And the apostle here by the expression "is crucified" doubtless refers to the painful and protracted struggle which everyone goes through when his evil propensities are subdued; when his corrupt nature is slain; and when, a converted sinner, he gives himself up to God. Sin dies within him, and he becomes dead to the world, and to sin; "for as by the cross death is most lingering and severe, so that corrupt nature is not subdued but by anguish." (Grotius.) All who have been born again can enter into this description. They remember "the wormwood and the gall." They remember the anguish of conviction; the struggle of corrupt passion for the ascendency; the dying convulsions of sin in the heart; the long and lingering conflict before it was subdued, and the soul became submissive to God. Nothing will better express this than the lingering agony of crucifixion: and the argument of the apostle is, that as sin has produced such an effect, and as the Christian is now free from its embrace and its power, he will live to God.

With him - The word "with" σύν sun here is joined to the verb "is crucified" and means "is crucified as he was."

That the body of sin - This expression doubtless means the same as that which he had just used, "our old man," But why the term "body" is used, has been a subject in which interpreters have not been agreed. Some say that it is a Hebraism, denoting mere intensity or emphasis. Some that it means the same as flesh, that is, denoting our sinful propensities and lusts. Grotius thinks that the term "body" is elegantly attributed to sin, because the body of man is made up of many members joined together compactly, and sin also consists of numerous vices and evil propensities joined compactly, as it were, in one body. But the expression is evidently merely another form of conveying the idea contained in the phrase "our old man" - a personification of sin as if it had a living form, and as if it had been put to death on a cross. It refers to the moral destruction of the power of sin in the heart by the gospel, and not to any physical change in the nature or faculties of the soul; compare Colossians 2:11.

Might be destroyed - Might be put to death; might become inoperative and powerless. Sin becomes enervated, weakened, and finally annihilated, by the work of the Cross.

We should not serve - Should not be the slave of sin δουλεύειν douleuein. That we should not be subject to its control. The sense is, that before this we were slaves of sin (compare Romans 6:17,) but that now we are made free from this bondage, because the moral death of sin has freed us from it.

Sin - Sin is here personified as a master that had dominion over us, but is now dead.

6:6 Our old man - Coeval with our being, and as old as the fall; our evil nature; a strong and beautiful expression for that entire depravity and corruption which by nature spreads itself over the whole man, leaving no part uninfected. This in a believer is crucified with Christ, mortified, gradually killed, by virtue of our union with him.That the body of sin - All evil tempers, words, and actions, which are the "members" of the "old man," Colossians 3:5 , might be destroyed.
