"The man who historically conveyed the most to us about Jesus, Paul, admits he is a screw up aka sinner. He cannot be good. (Remember Jesus said also only his father in heaven is good.) This runs up against what is the perceived role of the church in American culture...teach kids and adults how to be good, moral people. Thus our over emphasis on the 10 Commandment rather than life in Christ. (We have made them into a false idol.)
Romans 7 which is Paul writing - 'But I need something more! For if I know the law but still can't keep it, and if the power of sin within me keeps sabotaging my best intentions, I obviously need help! I realize that I don't have what it takes. I can will it, but I can't do it. I decide to do good, but I don't really do it; I decide not to do bad, but then I do it anyway. My decisions, such as they are, don't result in actions. Something has gone wrong deep within me and gets the better of me every time.
It happens so regularly that it's predictable. The moment I decide to do good, sin is there to trip me up. I truly delight in God's commands, but it's pretty obvious that not all of me joins in that delight. Parts of me covertly rebel, and just when I least expect it, they take charge.
I've tried everything and nothing helps. I'm at the end of my rope. Is there no one who can do anything for me? Isn't that the real question?
The answer, thank God, is that Jesus Christ can and does. He acted to set things right in this life of contradictions where I want to serve God with all my heart and mind, but am pulled by the influence of sin to do something totally different.'" - Hobart Rhodeheaver
