Law of sin—The law caused sin to "revive" (v. 9), literally, "become alive." Sin takes on an active force throughout this passage, which climaxes in this expression, "the law of sin." It refers to that in man which is sold under sin. It is "the law of sin and death" in Romans 8:2. Apart from the indwelling Holy Spirit, the law of sin would dominate in Paul's life.
