I heard another member say "fight the good fight," and this reminded me of my own experience and how wrong my thinking was.  My sponsor said to me that I cannot fight lust because I'm powerless to fight lust. He also said that God is not some big dog I get on the back of and say "sick 'em, boy."  No: I must surrender lust and leave the scene of the fight. I don't even get to watch God defeat lust. I leave the scene and speak with my sponsor, and surrender it all to God.
