I dont think God ever gives us more than we can handle, but there was never a promise of a life without trials and challenges. Its what we do when faced with these things that represents our true character & our faith.
I like the Footprints in the sand poem, and these verses:
Mark 9:23 - Jesus said unto him, If thou canst believe, all things [are] possible to him that believeth.
Mark 10:27 - .......for with God all things are possible.
