romans 7:5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death. - Free Bible Online

      5. For when we were in the flesh--in our unregenerate state, as we came into the world. See on Joh 3:6 and Ro 8:5-9.
      the motions--"passions" (Margin), "affections" (as in Ga 5:24), or "stirrings."
      of sins--that is, "prompting to the commission of sins."
      which were by the law--by occasion of the law, which fretted, irritated our inward corruption by its prohibitions. See on Ro 7:7-9.
      did work in our members--the members of the body, as the instruments by which these inward stirrings find vent in action, and become facts of the life. See on Ro 6:6.
      to bring forth fruit unto death--death in the sense of Ro 6:21. Thus hopeless is all holy fruit before union to Christ.
