Paul explains the human experience perfectly in Romans 7:15, I do not understand what I do. For what I want to do I do not do, but what I hate I do. Just because we have “head knowledge” does not mean we have all the answers for dealing with sin. Self-determination is also not an answer for dealing with sin because the issue is not our lack of determination. And just because we have become a Christian does not mean we taken away all sin or the temptation from from our lives. In the end, it is important to realize salvation comes from a moment of faith, but becoming like Christ is a lifelong endeavor.
