Now then it is no more I that do it, but sin that dwelleth in me.

Now then it is no longer I that do it, but the sin that dwells in me.

and now it is no longer I that work it, but the sin dwelling in me,

and now it is no longer I that do these things, but the sin which has its home within me does them.

So it is no longer I who do it, but the sin living in me.

But I am then acting not according to the law, but according to the sin which lives within me.

This being so, the action is no longer my own, but is done by the sin which is within me.

Nunc vero non jam illud operor ego, sed quod habitat in me peccatum.

Now it is no more I who do it, etc. This is not the pleading of one excusing himself, as though he was blameless, as the case is with many triflers who think that they have a sufficient defense to cover all their wickedness, when they cast the blame on the flesh; but it is a declaration, by which he shows how very far he dissented from his own flesh in his spiritual feeling; for the faithful are carried along in their obedience to God with such fervour of spirit that they deny the flesh. This passage also clearly shows, that Paul speaks here of none but of the godly, who have been already born again; for as long as man remains like himself, whatsoever he may be, he is justly deemed corrupt; but Paul here denies that he is wholly possessed by sin; nay, he declares himself to be exempt from its bondage, as though he had said, that sin only dwelt in some part of his soul, while with an earnest feeling of heart he strove for and aspired after the righteousness of God, and clearly proved that he had the law of God engraven within him.

Footnotes

1 - The last clause of this verse is worthy of notice, as the expression "indwelling sin" seems to have arisen from the words he oikousa en emoi -- "which dwells in me." Sin was in him as in a house or dwelling; it was an in-habiting sin, or that which is in-abiding or resident. -- Ed.

It is no more I that do it - This is evidently figurative language, for it is really the man that sins when evil is committed. But the apostle makes a distinction between sin and what he intends by the pronoun "I". By the former he evidently means his corrupt nature. By the latter he refers to his renewed nature, his Christian principles. He means to say that he does not approve or love it in his present state, but that it is the result of his native propensities and passions. In his heart, and conscience, and habitual feeling, he did not choose to commit sin, but abhorred it. Thus, every Christian can say that he does not choose to do evil, but would wish to be perfect; that he hates sin, and yet that his corrupt passions lead him astray.
But sin - My corrupt passions and native propensities.
That dwelleth in me - Dwelling in me as its home. This is a strong expression, denoting that sin had taken up its habitation in the mind, and abode there. It had not been yet wholly dislodged. This expression stands in contrast with another that occurs, where it is said that "the Spirit of God dwells" in the Christian, Romans 8:9; 1-Corinthians 3:16. The sense is, that he is strongly influenced by sin on the one hand, and by the Spirit on the other. From this expression has arisen the phrase so common among Christians, in-dwelling sin.

Now then it is no more I - It is not that I which constitutes reason and conscience, but sin-corrupt and sensual inclinations, that dwelleth in me - that has the entire domination over my reason, darkening my understanding, and perverting my judgment; for which there is condemnation in the law, but no cure. So we find here that there is a principle in the unregenerate man stronger than reason itself; a principle which is, properly speaking, not of the essence of the soul, but acts in it, as its lord, or as a tyrant. This is inbred and indwelling sin - the seed of the serpent; by which the whole soul is darkened, confused, perverted, and excited to rebellion against God.

Now then it is no more I that do it, but (z) sin that dwelleth in me.
(z) That natural corruption, which adheres strongly even to those that are regenerated, and is not completely gone.

Now then, it is no more I that do it,.... This is another inference, deduced from what is before said, that since he did not approve, but hated what he did, and willed the contrary, it was not he as spiritual, as born again, as a new man, a new creature, that did it; see 1-John 3:9. He says,
But sin that dwelleth in me; the old man, the carnal I, the evil present with him, the law in his members; which not only existed in him, and wrought in him, and that at times very strongly, but dwelt in him, had its abode in him, as it has in all regenerate persons, and will have, as long as they are in the body.

Now then it is no more I--my renewed self.
that do it--"that work it."
but sin which dwelleth in me--that principle of sin that still has its abode in me. To explain this and the following statements, as many do (even BENGEL and THOLUCK), of the sins of unrenewed men against their better convictions, is to do painful violence to the apostle's language, and to affirm of the unregenerate what is untrue. That coexistence and mutual hostility of "flesh" and "spirit" in the same renewed man, which is so clearly taught in Romans 8:4, &c., and in Galatians 5:16, &c., is the true and only key to the language of this and the following verses. (It is hardly necessary to say that the apostle means not to disown the blame of yielding to his corruptions, by saying, "it is not he that does it, but sin that dwelleth in him." Early heretics thus abused his language; but the whole strain of the passage shows that his sole object in thus expressing himself was to bring more vividly before his readers the conflict of two opposite principles, and how entirely, as a new man--honoring from his inmost soul the law of God--he condemned and renounced his corrupt nature, with its affections and lusts, its stirrings and its outgoings, root and branch).

It is no more I that can properly be said to do it, but rather sin that dwelleth in me - That makes, as it were, another person, and tyrannizes over me.
