Be careful what you ask for...

Asking God to make you a stronger person can be a dangerous thing to do.  Just as bodybuilders like to say, 'No pain, no gain,' the same concept applies to virtue as well.  Just as a warrior cannot become a Marine without first undergoing The Crucible so we cannot become stronger people without first undergoing suffering.  You cannot get something for nothing.  The point?  When you ask God to make you strong, don't expect Him to just give it to you.  After all, He doesn't owe you anything, He's God.  He will make you strong, but you probably won't like the way He goes about doing it.  Suck it up and stick it out and when you look back you'll see how all the shit you went through was totally worth it.
