(21) I find then a law.--Of the many ways of taking this difficult verse, two seem to stand out as most plausible or possible. In any case "a law" should be rather "the law." This is taken by the majority of commentators, including Bishop Ellicott, in the sense of "rule," "habitually-repeated fact." "I find this law, or this rule, that when I would do good evil is present with me." Such is my constant and regular experience. The objection to this interpretation is that it gives to the word "law" an entirely different sense from that which it bears in the context, or in any other part of St. Paul's writings. The other view is that which is maintained by Dr. Vaughan. According to this we should have to assume an anacoluthon. The Apostle begins the sentence as if he were going to say, "I find therefore the Law (the Mosaic law), when I desire to do good, unable to help me;" but he changes somewhat the form of the sentence in the latter portion, and instead of saying "I find the Law unable to help me," he says, "I find that evil is at my side." "To me" is also repeated a second time, in the Greek superfluously, for the sake of greater clearness. Or perhaps a still simpler and better explanation would be that the Apostle had intended in the first instance to say, "I find the Law, when I wish to do good, putting evil before me," and then shrank (as in Romans 7:7) from using so harsh an expression, and softened it by turning the latter half of the sentence into a passive instead of an active form--"I find the Law, when I wish to do good--that evil is put before me."

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.I find then a law,.... This is to be understood either of the corruption of nature, which he found by experience to be in him; and which, because of its force, power, and prevalence it sometimes had in him, he calls "a law"; it forcibly demanding compliance with its lusts; and is the same with what he calls "evil", and which the Jews so frequently style "the evil imagination", by which they mean the corruption of nature; and one of the seven names, and the first of them, by which it is called, they tell us (k), is, "evil"; the very name it goes by here, and which they say God calls it, Genesis 6:5; and well may it be so called, since it is originally, naturally, and continually evil; it is evil in its nature and consequences; it is the source and spring of all evil:

that when I would do good; says the apostle, as soon as any good thought arises in me, any good resolution is entered into by me, or I am about to do anything that is good,

evil, the vitiosity of nature,

is present with me, and hinders me; it came into the world with me, and it has continued with me ever since; it cleaves close unto me, it lies very nigh me, and whenever there is any motion to that which is good, it starts up, which seemed to lie asleep before, and exerts itself, so that I cannot do the good I would. The Jews say (l), there are , "two hearts" in man, the good imagination, and the evil imagination. The apostle here speaks as of two wills in regenerate men, one to good, and another to evil: or this may be understood of the law of God, which he found agreed with his mind, willing that which is good, though sin lay so near to him; or he found that willing that which was good was the law of God, very agreeable to it; and that the law was on his side, favouring him, encouraging him to that which is good, though sin kept so close to him; to which sense agree the following words.
