Römer 7:23

But I see another--it should be "a different" law in my members--(See on Rom 7:5). warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members--In this important verse, observe, first, that the word "law" means an inward principle of action, good or evil, operating with the fixedness and regularity of a law. The apostle found two such laws within him; the one "the law of sin in his members," called (in Gal 5:17, Gal 5:24) "the flesh which lusteth against the spirit," "the flesh with the affections and lusts," that is, the sinful principle in the regenerate; the other, "the law of the mind," or the holy principle of the renewed nature. Second, when the apostle says he "sees" the one of these principles "warring against" the other, and "bringing him into captivity" to itself, he is not referring to any actual rebellion going on within him while he was writing, or to any captivity to his own lusts then existing. He is simply describing the two conflicting principles, and pointing out what it was the inherent property of each to aim at bringing about. Third, when the apostle describes himself as "brought into captivity" by the triumph of the sinful principle of his nature, he clearly speaks in the person of a renewed man. Men do not feel themselves to be in captivity in the territories of their own sovereign and associated with their own friends, breathing a congenial atmosphere, and acting quite spontaneously. But here the apostle describes himself, when drawn under the power of his sinful nature, as forcibly seized and reluctantly dragged to his enemy's camp, from which he would gladly make his escape. This ought to settle the question, whether he is here speaking as a regenerate man or the reverse.

We may observe in this chapter, I. Our freedom from the law further urged as an argument to press upon us sanctification (Rom 7:1-6). II. The excellency and usefulness of the law asserted and proved from the apostle's own experience, notwithstanding (Rom 7:7-14). III. A description of the conflict between grace and corruption in the heart (Rom 7:14, Rom 7:15, to the end).

7:23 another power. . . . This power (literally another law. . . . This law): Paul plays on the word law in these verses. Opposed to God’s law (7:22) is another law, a ruling power that prevents Paul from submitting to God’s law even though he fully agrees with it.
