7:15 I do not understand. Paul is able to analyze, but not to explain, the contrast between himself and the “sin that dwells within me” (vv. 17, 20). There is a real and bewildering conflict between the energies of sin and of grace in his life. He hints, however, that indwelling sin is a temporary lodger in him. While sin still accompanies his new identity in Christ in this life, the new identity will result in the final triumph over indwelling sin (6:2–14).
