The story is told about a certain mountain climber who slipped and fell off a cliff, but on the way down, he grabbed the roots of a tree and held on for dear life.  Looking beneath him, he saw a sheer drop of several thousand feet.  He yelled for help but none came.  Finally, he cried out, "God, help me!"  And then came a voice saying, "Just turn loose; I'll catch you," but looking around he didn't see anyone and not liking the alternatives called out again, "Anybody else up there?"
