"We must fight the enemy to the end", this must be our mentality in fighting the battle against the things that hold us back from fully committing to the priesthood.  

The end thus is in view when we have broken free from the bondage of our addictions and cannot be stirred up again by them.  

In other words, when we do not have any affection for these addictions because we consider them as sins against God, are desperate enough to be freed from its power and believe that with God it is possible to overcome our addictions then we are on track towards victory.
