19 For the good that I would I do not: but the evil which I would not, that I do.
19 For I do not do the good I want to do, but the evil I do not want to do-this I keep on doing.
19 For I do not do the good I want, but the evil I do not want is what I keep on doing.
19 I decide to do good, but I don't really do it; I decide not to do bad, but then I do it anyway.
19 For the good that I will to do, I do not do; but the evil I will not to do, that I practice.
19 I want to do what is good, but I don't. I don't want to do what is wrong, but I do it anyway.
Matthew Henry's Commentary on Romans 7:19
Commentary on Romans 7:18-22
(Read Romans 7:18-22)
The more pure and holy the heart is, it will have the more quick feeling as to the sin that remains in it. The believer sees more of the beauty of holiness and the excellence of the law. His earnest desires to obey, increase as he grows in grace. But the whole good on which his will is fully bent, he does not do; sin ever springing up in him, through remaining corruption, he often does evil, though against the fixed determination of his will. The motions of sin within grieved the apostle. If by the striving of the flesh against the Spirit, was meant that he could not do or perform as the Spirit suggested, so also, by the effectual opposition of the Spirit, he could not do what the flesh prompted him to do. How different this case from that of those who make themselves easy with regard to the inward motions of the flesh prompting them to evil; who, against the light and warning of conscience, go on, even in outward practice, to do evil, and thus, with forethought, go on in the road to perdition! For as the believer is under grace, and his will is for the way of holiness, he sincerely delights in the law of God, and in the holiness which it demands, according to his inward man; that new man in him, which after God is created in true holiness.
