Nothing gives one a more spuriously good conscience than keeping rules. (C. S. Lewis, British Christian apologist) 

It feels good to play by the rules, doesn’t it? Unless, of course, the rules prevent us from doing something we want to do that’s against the rules. Sometimes, we have a false sense of security because we are good rule-keepers. We forget the spirit of the rules, and we ignore the deeper intentions of doing good, which is to follow the Golden Rule.

Do to others as you would have them do to you. (Luke 6:31)
