Though the true Christian is an heir of complete salvation, yet he is never completely saved from sin while he is in this world. Though he is transformed into the Divine image, by the renewing of his mind,
there is, notwithstanding, a law in his members which wars against the law of his mind, and often brings him into captivity to the law of sin, so as to make him sometimes exclaim as the holy apostle Paul did, "Oh wretched man that I am ! who shall deliver me from the body of this death?" who shall deliver me from this cruel, this deceitful enemy, which often wounds my soul, disturbs my peace, retards my progress in the spiritual life, darkens my evidences for heaven, and prevents my complete happiness?
How long shall I go mourning, because of the oppression of this enemy! The Christian shall have reason thus to complain of indwelling sin, while he is in this valley of tears; and the higher the degree of holiness is to which he attains, the more sensibly he will feel it, and the more bitterly will he complain of it.
The triumphing of this enemy, however, is but short; its destruction is fast approaching. Yet a little while, and Jesus will call the oppressed believer, not only to put off the tabernacle of flesh and blood, but to put off the body of sin and death, so as never to be troubled with it any more forever.
Then sinning and suffering, sorrowing and sighing, shall cease at once. When spiritual death is entirely swallowed up in victory, "the Lord God will wipe away tears from off all faces, and the rebuke of his people will he take away." — Thus Jesus saves his people from the guilt, the dominion, the defilement, and the very being of sin: He saves them from the guilt of sin, in justification; from the dominion of sin, in conversion; from the defilement of sin, in sanctification; and from the very being of it, in glorification.- John Colquhoun.
