Romans 7 portrays a picture of us as sinners that is deeper and more complex than we tend to think. A good word picture or story to illustrate much of this is the classic short. Novel Dr. Jekyll and Mr. Hyde. The law or religion won’t fix us Mr. Hydes, only bring out more evil. Our only hope is to be married to another, namely the perfect spouse who in their face is perfect love, acceptance, encouragement, and grace that radically transforms our life. Paul says that this spouse is Christ in Romans 7:1-7. Tim Keller references this story in his series on ‘How people change’ in his Sermon entitled ‘Splitness’.
