Being Content in all circumstances

We all go through incredible challenges in our lifetimes.  Some of these are from our own choices, but others are circumstances beyond our control.  How did Paul get through all of his circumstances?  Being shipwrecked, stoned, tortured, imprisoned multiple times would qualify as difficult circumstances.  He got through them because of his faith and relationship with Jesus.  Because of that relationship he was able to be content in all circumstances.  And when it got really hard he sang, he worshiped God.  And therin lies our clue as to how we too can respond in our difficulties.  We sing.  We worship.
