"Redemption," in its simplest meaning, is the act of delivering a slave from captivity by the payment of ransom. So that it contains in its application to the effect of Christ's death, substantially the same figure as in the previous clause which spoke of a deliverance from a tyrant, only that what was there represented as an act of Power is here set forth as the act of self-sacrificing Love which purchases our freedom at a heavy cost. That ransom price is said by Christ Himself to be "His life," and His Incarnation to have the paying of that price as one of its two chief objects. So the words added here by quotation from the companion Epistle are in full accordance with New Testament teaching; but even omitting them, the meaning of the clause is unmistakable. Christ's death breaks the chains which bind us, and sets us free. By it He acquires us for Himself. That transcendent act of sacrifice has such a relation to the Divine government on the one hand, and to the "sin of the world," as a whole, on the other, that by it all who trust in Him are delivered from the most real penal consequences of sin and from the dominion of its darkness over their natures. We freely admit that we cannot penetrate to the understanding of _how_ Christ's death thus avails. But just because the _rationale_ of the doctrine is avowedly beyond our limits, we are barred from asserting that it is incompatible with God's character, or with common justice, or that it is immoral, and the like. When we know God through and through, to all the depths and heights and lengths and breadths of His nature, and when we know man in like manner, and when, consequently, we know the relation between God and man as perfectly, and not till then, we shall have a right to reject the teaching of Scripture on this matter, on such grounds. Till then, let our faith lay hold on the fact, though we do not understand the "how" of the fact, and cling to that cross which is the great power of God unto salvation, and the heart-changing exponent of the love of Christ which passeth knowledge.
The essential and first element in this redemption is "the forgiveness of sins." Possibly some misconception of the nature of redemption may have been associated with the other errors which threatened the Colossian Church, and thus Paul may have been led to this emphatic declaration of its contents. Forgiveness, and not some mystic deliverance by initiation or otherwise from the captivity of flesh and matter, is redemption. There is more than forgiveness in it, but forgiveness lies on the threshold; and that not only the removal of legal penalties inflicted by a specific act, but the forgiveness of a father. A sovereign pardons when he remits the sentence which law has pronounced. A father forgives when the free flow of his love is unhindered by his child's fault, and he may forgive and punish at the same moment. The truest "penalty" of sin is that death which consists in separation from God; and the conceptions of judicial pardon and fatherly forgiveness unite when we think of the "remission of sins" as being the removal of that separation, and the deliverance of heart and conscience from the burden of guilt and of a father's wrath.
Such forgiveness leads to that full deliverance from the power of darkness, which is the completion of redemption. There is deep meaning in the fact that the word here used for "forgiveness," means literally, "sending away." Pardon has a mighty power to banish sin, not only as guilt, but as habit. The waters of the gulf stream bear the warmth of the tropics to the icy north, and lave the foot of the glaciers on its coast till they melt and mingle with the liberating waves. So the flow of the forgiving love of God thaws the hearts frozen in the obstinacy of sin, and blends our wills with itself in glad submission and grateful service.
