Or it could all just be random and without meaning at all.

If God really did never give us any more than we could handle, wouldn't we all be immortal?  I mean, He gives us cancer, and sometimes it kills us so obviously we can't all handle that.  And He gives us depression, which some of us can't handle. In fact, if I really did believe that some dude was deliberately handing out every random occurrence in my life, I think I'd be pretty pissed off that He handpicked the "brain cancer in her 60s" card for my mom.  Because really, what a prick!
