Too often we get absorbed with the consequences of our sin in relation to other people, and we don't recognize the breach in fellowship with God that it makes often when we sin. I think that we fail in many cases to have a deep enough relationship with God to understand that our repentance must be oriented to Him and Him primarily because it's Him we must turn to. The turning from aspect of sin is one thing, but unless we have turned from sin and to God, very little has been accomplished.
