In Romans 7, "he is discussing the Christian struggle (more briefly touched in Galatians [ch. 5:17]), which believers constantly feel in themselves in the conflict between flesh and spirit. But the Spirit comes, not from nature, but from regeneration. Moreover, it is clear that the apostle is speaking of these regenerated, because when he had said that no good dwelt in him, he adds the explanation that he is referring to his flesh [Rom. 7:18].
"Accordingly, he declares that it is not he who does evil, but sin dwelling in him. [Rom. 7:20.] What does he mean by this correction: "In me, that is, in my flesh" [Rom. 7:18]? It is as if he were speaking in this way: "Good does not dwell in me of myself, for nothing good is to be found in my flesh." Hence follows that form of an excuse: "I myself do not do evil, but sin that dwells in me" [Rom. 7:20]. This excuse applies only to the regenerate who tend toward good with the chief part of their soul.
"Now the conclusion appended clearly explains this whole matter: "For I delight in the law . . . according to the inner man, but I see in my members another law at war with the law of my mind" [Rom. 7:22-23]. Who would have such strife in himself but a man who, regenerated by the Spirit of God, bears the remains of his flesh about with him?"
Oops. I guess Calvin isn't inspired. No wonder so many fundamentalist Calvinists are up in arms about the "new" perspective. It's hard to kick against the pricks.
