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.
II. We have here, the continuous growth of the new man, its aim and pattern.
The thought of the garment passes for the moment out of sight, and the Apostle enlarges on the greatness and glory of this "new man," partly as a stimulus to obeying the exhortation, partly, with allusion to some of the errors which he had been combating, and partly because his fervid spirit kindles at the mention of the mighty transformation.
The new man, says he, is "being renewed." This is one of the instances where minute accuracy in translation is not pedantic, but clear gain. When we say, with the Authorised Version, "is renewed," we speak of a completed act; when we say with the Revised Version, "is being renewed," we speak of a continuous process; and there can be no question that the latter is the true idea intended here. The growth of the new man is constant, perhaps slow and difficult to discern, if the intervals of comparison be short. But like all habits and powers it steadily increases. On the other hand, a similar process works to opposite results in the "old man," which, as Paul says in the instructive parallel passage in the Epistle to the Ephesians (iv. 22), "waxeth corrupt, after the lusts of deceit." Both grow according to their inmost nature, the one steadily upwards; the other with accelerating speed downwards, till they are parted by the whole distance between the highest heaven and the lowest abyss. So mystic and awful is that solemn law of the persistent increase of the true ruling tendency of a man's nature, and its certain subjugation of the whole man to itself!
It is to be observed that this renewing is represented in this clause, as done _on_ the new man, not by him. We have heard the exhortation to a continuous appropriation and increase of the new life by our own efforts. But there is a Divine side too, and the renewing is not merely effected by us, nor due only to the vital power of the new man, though growth is the sign of life there as everywhere, but is "the renewing by the Holy Ghost," whose touch quickens and whose indwelling renovates the inward man day by day. So there is hope for us in our striving, for He helps us; and the thought of that Divine renewal is not a pillow for indolence, but a spur to intenser energy, as Paul well knew when he wove the apparent paradox, "work out your own salvation, for it is God that worketh in you."
