This retrospect enforces the main exhortation. It is meant to awaken penitence, and the thought that time enough has been wasted and incense enough offered on these foul altars. It is also meant to kindle thankfulness for the strong, loving hand which has drawn them from that pit of filth, and by both emotions to stimulate the resolute casting aside of that evil in which they once, like others, wallowed. Their joy on the one hand and their contrition on the other should lead them to discern the inconsistency of professing to be Christians and yet keeping terms with these old sins. They could not have the roots of half their lives above and of the other half down here. The gulf between the present and past of a regenerate man is too wide and deep to be bridged by flimsy compromises. "A man who is perverse in his two ways," that is, in double ways, "shall fall in one of them," as the Book of Proverbs has it. The attempt to combine incompatibles is sure to fail. It is impossible to walk firmly if one foot be down in the gutter and the other up on the curb-stone. We have to settle which level we shall choose, and then to plant both feet there. V. We have, as conclusion, a still wider exhortation to an entire stripping off of the sins of the old state. The whole force of the contrast and contrariety between the Colossian Christians' past and present lies in that emphatic "now." They as well as other heathen had been walking, because they had been living, in these muddy ways. But now that their life was hid with Christ in God; now that they had been made partakers of His death and resurrection, and of all the new loves and affinities which therein became theirs; now they must take heed that they bring not that dead and foul past into this bright and pure present, nor prolong winter and its frosts into the summer of the soul. "Ye also." There is another "ye also" in the previous verse--"ye also walked," that is, you in company with other Gentiles followed a certain course of life. Here, by contrast, the expression means "you, in common with other Christians." A motive enforcing the subsequent exhortation is in it hinted rather than fully spoken. The Christians at Colossæ had belonged to a community which they have now left in order to join another. Let them behave as their company behaves. Let them keep step with their new comrades. Let them strip themselves, as their new associates do, of the uniform which they wore in that other regiment.
