It's weird, isn't it? When I think about it, I feel awful, and then I forget, and sin again! I'm thankful that St. Paul understood how I feel. See Romans 7:15 "What I do, I do not understand. For I do not do what I want, but I do what I hate." and Romans 7:19 "For I do not do the good I want, but I do the evil I do not want." and Romans 7:24-25 "Miserable one that I am! Who will deliver me from this mortal body? Thanks be to God through Jesus Christ our Lord. Therefore I myself, with my mind, serve the law of God but, with my flesh, the law of sin."
