This passage does not represent the apostle as one that walked after the flesh, but as one that had it greatly at heart, not to walk so. And if there are those who abuse this passage, as they also do the other Scriptures, to their own destruction, yet serious Christians find cause to bless God for having thus provided for their support and comfort.
We are not, because of the abuse of such as are blinded by their own lusts, to find fault with the scripture, or any just and well warranted interpretation of it. And no man who is not engaged in this conflict, can clearly understand the meaning of these words, or rightly judge concerning this painful conflict, which led the apostle to bemoan himself as a wretched man, constrained to what he abhorred.
He could not deliver himself; and this made him the more fervently thank God for the way of salvation revealed through Jesus Christ, which promised him, in the end, deliverance from this enemy. So then, says he, I myself, with my mind, my prevailing judgement, affections, and purposes, as a regenerate man, by Divine grace, serve and obey the law of God; but with the flesh, the carnal nature, the remains of depravity, I serve the law of sin, which wars against the law of my mind.
Not serving it so as to live in it, or to allow it, but as unable to free himself from it, even in his very best state, and needing to look for help and deliverance out of himself. It is evident that he thanks God for Christ, as our deliverer, as our atonement and righteousness in himself, and not because of any holiness wrought in us.
He knew of no such salvation, and disowned any such title to it. He was willing to act in all points agreeable to the law, in his mind and conscience, but was hindered by indwelling sin, and never attained the perfection the law requires.
What can be deliverance for a man always sinful, but the free grace of God, as offered in Christ Jesus? The power of Divine grace, and of the Holy Spirit, could root out sin from our hearts even in this life, if Divine wisdom had not otherwise thought fit.
But it is suffered, that Christians might constantly feel, and understand thoroughly, the wretched state from which Divine grace saves them; might be kept from trusting in themselves; and might ever hold all their consolation and hope, from the rich and free grace of God in Christ.
