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.
