Romans 7:21-23
(21) I find then a law, that, when I would do good, evil is present with me.
(22) For I delight in the law of God after the inward man:
(23) But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Paul was a person who tried to learn from his experiences, so now he concluded, I find this law at work. This is not the Mosaic Law, of course, but a principle drawn from experience. Also in 8:2 “law” (nomos) means principle. This law or principle is the reality of ever-present evil in an individual whenever he wants to do good. Paul held fast to the fact that, as he said, In my inner being I delight in God’s Law (cf. 7:25). “In my inner being” is literally, “according to the inner man.” (The “inner man” is used in the Gr. NT also in 2 Cor. 4:16 and Eph. 3:16.) Delight in God’s Law was the psalmist’s response, stated repeatedly in Psalm 119 (e.g., vv. 16, 24, 47; cf. Ps. 1:2). Because of regeneration, a believer has a new nature or capacity for loving spiritual truths. Yet, recognizing the facts of experience, Paul said he saw another law or principle at work within him. This is the principle of sin. Paul called it “sin living in me” (Rom. 7:17, 20), “evil” right there with me (v. 21), and “the sinful nature” (vv. 5, 18, 25).
This principle is continually doing two things: waging war against the law of the believer’s mind and making him a prisoner of the law of sin at work within his members. The indwelling principle of sin is constantly mounting a military campaign against the new nature, trying to gain victory and control (cf. “slave” in vv. 14, 25 and “slaves” in 6:17, 19-20), of a believer and his actions. The new nature is called “the law” of the “mind” (noos; cf. 7:25) because it has the capacity for perceiving and making moral judgments. Further, despite a believer’s identification with Jesus Christ’s death and resurrection and his efforts to have Christ-honoring attitudes and actions, he cannot in his own power resist his indwelling sin nature. In and of himself he repeatedly experiences defeat and frustration.
