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.
