We have already found the same idea presented under the forms of death and resurrection. The “death” is equivalent to the “putting off of the old,” and the “resurrection” to “the putting on of the new man.” That figure of a change of dress to express a change of moral character is very obvious, and is frequent in Scripture. Many a psalm breathes such prayers as, “Let Thy priests be clothed with righteousness.” Zechariah in vision saw the high-priestly representative of the nation standing before the Lord “in filthy garments,” and heard the command to strip them off him, and clothe him in festival robes, in token that God had “caused his iniquity to pass from him.” Christ spoke His parable of the man at the wedding feast without the wedding garment, and of the prodigal, who was stripped of his rags stained with the filth of the swine troughs, and clothed with the best robe. Paul in many places touches the same image, as in his ringing exhortation—clear and rousing in its notes like the morning bugle—to Christ’s soldiers, to put off their night gear, “the works of darkness,” and to brace on the armour of light, which sparkles in the morning sunrise. Every reformatory and orphanage yields an illustration of the image, where the first thing done is to strip off and burn the rags of the new comers, then to give them a bath and dress them in clean, sweet, new clothes. Most naturally dress is taken as the emblem of character, which is indeed the garb of the soul. Most naturally habit means both costume and custom.

But here we have a strange paradox introduced, to the ruining of the rhetorical propriety of the figure. It is a “new man” that is put on. The Apostle does not mind hazarding a mixed metaphor, if it adds to the force of his speech, and he introduces this thought of the new man, though it somewhat jars, in order to impress on his readers that what they have to put off and on is much more truly part of themselves than an article of dress is. The “old man” is the unregenerate self; the new man is, of course, the regenerate self, the new Christian moral nature personified. There is a deeper self which remains the same throughout the change, the true man, the centre of personality; which is, as it were, draped in the moral nature, and can put it off and on. I myself change myself. The figure is vehement, and, if you will, paradoxical, but it expresses accurately and forcibly at once the depth of the change which passes on him who becomes a Christian, and the identity of the person through all change. If I am a Christian, there has passed on me a change so thorough that it is in one aspect a death, and in another a resurrection; in one aspect it is a putting off not merely of some garb of action, but of the old man, and in another a putting on not merely of some surface renovation, but of a new man—which is yet the same old self.

This entire change is taken for granted by Paul as having been realised in every Christian. It is here treated as having taken place at a certain point of time, namely when these Colossians began to put their trust in Jesus Christ, and in profession of that trust, and as a symbol of that change, were baptized.

Of course the contrast between the character before and after faith in Christ is strongest when, like the Christians at Colossæ, converts have been brought out of heathenism. With us, where some knowledge of Christianity is widely diffused, and its indirect influence has shaped the characters even of those who reject it, there is less room for a marked revolution in character and conduct. There will be many true saints who can point to no sudden change as their conversion; but have grown up, sometimes from childhood, under Christian influences, or who, if they have distinctly been conscious of a change, have passed through it as gradually as night passes into day. Be it so. In many respects that will be the highest form of experience. Yet even such souls will be aware of a “new man” formed in them which is at variance with their own old selves, and will not escape the necessity of the conflict with their lower nature, the immolation and casting off of the unregenerate self. But there are also many people who have grown up without God or Christ, who must become Christians by the way of sudden conversion, if they are ever to become Christians at all.

Why should such sudden change be regarded as impossible? Is it not a matter of every-day experience that some long ignored principle may suddenly come, like a meteor into the atmosphere, into a man’s mind and will, may catch fire as it travels, and may explode and blow to pieces the solid habits of a lifetime? And why should not the truth concerning God’s great love in Christ, which in too sad certainty is ignored by many, flame in upon blind eyes, and change the look of everything? The New Testament doctrine of conversion asserts that it may and does. It does not insist that everybody must become a Christian in the same fashion. Sometimes there will be a dividing line between the two states, as sharp as the boundary of adjoining kingdoms; sometimes the one will melt imperceptibly into the other. Sometimes the revolution will be as swift as that of the wheel of a locomotive, sometimes slow and silent as the movement of a planet in the sky. The main thing is that whether suddenly or slowly the face shall be turned to God.

But however brought about, this putting off of the old sinful self, is a certain mark of a Christian man. It can be assumed as true universally, and appealed to as the basis of exhortations such as those of the context. Believing certain truths does not make a Christian. If there have been any reality in the act by which we have laid hold of Christ as our Saviour, our whole being will be revolutionized; old things will have passed away—tastes, desires, ways of looking at the world, memories, habits, pricks of conscience and all cords that bound us to our God-forgetting past—and all things will have become new, because we ourselves move in the midst of the old things as new creatures with new love burning in our hearts and new motives changing all our lives, and a new aim shining before us, and a new hope illuminating the blackness beyond, and a new song on our lips, and a new power in our hands, and a new Friend by our sides.

This is a wholesome and most needful test for all who call themselves Christians, and who are often tempted to put too much stress on believing and feeling, and to forget the supreme importance of the moral change which true Christianity effects. Nor is it less needful to remember that this resolute casting off of the garment spotted by the flesh, and putting on of the new man, is a consequence of faith in Christ and is only possible as a consequence. Nothing else will strip the foul robes from a man. The moral change comes second, the union with Jesus Christ by faith must come first. To try to begin with the second stage, is like trying to begin to build a house at the second story.

But there is a practical conclusion drawn from this taken-for-granted change. Our text is introduced by “seeing that;” and though some doubts may be raised as to that translation and the logical connection of the paragraph, it appears on the whole most congruous with both the preceding and the following context, to retain it and to see here the reason for the exhortation which goes before—“Put off all these,” and for that which follows—“Put on, therefore,” the beautiful garment of love and compassion.

That great change, though taking place in the inmost nature whensoever a heart turns to Christ, needs to be wrought into character, and to be wrought out in conduct. The leaven is in the dough, but to knead it thoroughly into the mass is a lifelong task, which is only accomplished by our own continually repeated efforts. The old garment clings to the limbs like the wet clothes of a half-drowned man, and it takes the work of a lifetime to get quite rid of it. The “old man” dies hard, and we have to repeat the sacrifice hour by hour. The new man has to be put on afresh day by day.

So the apparently illogical exhortation, Put off what you have put off, and put on what you have put on, is fully vindicated. It means, Be consistent with your deepest selves. Carry out in detail what you have already done in bulk. Cast out the enemy, already ejected from the central fortress, from the isolated positions which he still occupies. You may put off the old man, for he is put off already; and the confidence that he is will give you strength for the struggle that still remains. You must put off the old man, for there is still danger of his again wrapping his poisonous rags about your limbs.
