Even if I thought I did believe that, the belief would still be a part of the movement of thought.  It would still be just words, concepts, ideas.  Saying that I believe in sunsets is entirely different than watching one and being witness to all of it's colors and shades of light.  Belief is built of thought.  Whatever is beyond belief is something that words do not approach.  You cannot know the unknowable through the known, through word or belief or mental concept.  Believing is still a part of the game, it's not enough.
