I do have a habit of dwelling on what I have done wrong, or could have done better. God doesn't want that. After repentance and reconciliation, there is no need for it. Instead I need to think of better things.
Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
Jesus did not come to bring us condemnation, but salvation. I love how this song brings that home for me.
