Faith part 2

I find it interesting that when I feel absolutely sure about my faith and belief system it gets rocked a bit.   I have stood strong in my beliefs for a very long, long time without question.  But recently the questions seem to be coming.  Honestly, I think it is God putting those questions out there, encouraging me to look farther and dig deeper.  Obviously questions will always be there regarding faith.  Obviously the answers will almost never be completely concrete.  Just when I thought that I was so on top of things and my spiritual journey had most certainly evolved beyond the rudimentary that is when the basic questions come back to mind.  Where are you God and what the heck do you want me to do?
