It consists in the "putting off the body of the flesh"--for "the sins of" is an interpolation. Of course a man does not shuffle off this mortal coil when he becomes a Christian, so that we have to look for some other meaning of the strong words. They are very strong, for the word "putting off" is intensified so as to express a complete stripping off from oneself, as of clothes which are laid aside, and is evidently intended to contrast the partial outward circumcision as the removal of a small part of the body, with the entire removal effected by union with Christ. If that removal of "the body of the flesh" is "not made with hands," then it can only be in the sphere of the spiritual life, that is to say, it must consist in a change in the relation of the two constituents of a man's being, and that of such a kind that, for the future, the Christian shall not live after the flesh, though he live in the flesh. "Ye are not in the flesh, but in the Spirit," says Paul, and again he uses an expression as strong as, if not stronger than that of our text, when he speaks of "the body" as "being destroyed," and explains himself by adding "that henceforth we should not serve sin." It is not the body considered simply as material and fleshly that we put off, but the body considered as the seat of corrupt and sinful affections and passions. A new principle of life comes into men's hearts which delivers them from the dominion of these, and makes it possible that they should live in the flesh, not "according to the lusts of the flesh, but according to the will of God." True, the text regards this divesting as complete, whereas, as all Christian men know only too sadly, it is very partial, and realised only by slow degrees. The ideal is represented here,--what we receive "in Him," rather than what we actually possess and incorporate into our experience. On the Divine side the change is complete. Christ gives complete emancipation from the dominion of sense, and if we are not in reality completely emancipated, it is because we have not taken the things that are freely given to us, and are not completely "_in_ Him." So far as we are, we have put off "the flesh." The change has passed on us if we are Christians. We have to work it out day by day. The foe may keep up a guerilla warfare after he is substantially defeated, but his entire subjugation is certain if we keep hold of the strength of Christ. Finally, this circumcision is described as "of Christ," by which is not meant that He submitted to it, but that He instituted it.
