The Unknown Parts

Several occurences, conversations and readings combined this week to make known to me a fact that was previpusly hidden. God orchestrated those events. Event 1: Wednesday evening meeting with friends and talking about prayer... specifically for this girl, confessing sins before God. I am glad I can come before Him and confess my sins because I know He is working in me and has forgiven me. But the point was brought up about sins of omission...those are harder to identify...but just as equally important to confess and be aware of. So if there are things I am NOT doing that I SHOULD be doing...and if I am unaware...how do I come to a point of being able to confess them? Bible:
