Romans 7:23

Another law in my members; i.e. a law quite different from the law of God, mentioned in the foregoing verse. By the law in the members understand natural corruption, which, like a law, commandeth and inclineth by sensual rewards and punishments; and by the law in the mind understand a principle of grace, which, as a law, as well as the other, commandeth and inelineth to that which is good. The law in the members and the law in the mind, are the same that are called flesh and Spirit, Galatians 5:17. These two laws and principles are in all regenerate persons, and are directly contrary to one another; hence there is continual warring and combating betwixt them; as is expressed in both these places, as also in James 4:1 1 Peter 2:11. Bringing me into captivity to the law of sin; i.e. drawing and hurrying me to the commission of sin, against my will and consent. He pursues the metaphor; the flesh doth not only war in the regenerate, but many times it overcomes and hath success: see Romans 7:15. To the law of sin which is in my members; i.e. to itself. The antecedent is put in the room of the relative: see Genesis 9:16, and elsewhere. The law in the members and the law of sin in the members are the same.
