This is the language of a regenerate soul, and it sums up the contents of the verses immediately preceding. The unregenerate man is wretched indeed, but he is a stranger to the “wretchedness” here expressed, for he knows nothing of the experience which evokes this wail. The whole context is devoted to a description of the conflict between the two natures in the child of God. “I delight in the law of God after the inward man” (v. 22), is true of none but born-again persons. But the one thus “delighting” discovers “another law in his members.” This reference must not be limited to his physical members, but is to be understood as including all the various parts of his carnal personality. This “other law” is also at work in the memory, the imagination, the will, the heart, etc.
This “other law,” says the apostle, warred against the law of his mind (the new nature), and not only so, it brought him “into captivity to the law of sin.” (v. 23) To what extent he was brought into “captivity” is not defined. But brought into captivity he was, as is every believer. The wandering of the mind when reading God’s Word, the issuing from the heart (Mark 7:21) of evil thoughts when we are engaged in prayer, the horrid images which sometimes come before us in the sleep-state— to name no others—are so many examples of being “brought into captivity to the law of sin.” “If the evil principle of our nature prevails in exciting one evil thought, it has taken us captive. So far it has conquered, and so far are we defeated, and made a prisoner” (Robert Haldane).
