What's gray?  It's not black, it's not white.  But it contains them both.  And that's the point.  Color is happy.  Color infuses us with a sense of existence, a sense of joy and meaning.  Moreover, there are things that can only be black and white, for instance, the existence of God.  Either God exists, or he does not.
     Is gray therefore unhappy?  Quite the opposite.  Gray is a statement of great insight.  Black and white doesn't always explain things fully.  It makes a statement without giving solid evidence that it is true.
     When we look at the world as gray, we come to understand that the most profound delineations permeating existence present puzzles that we cannot solve in black and white.  We can only look at them in gray.
     Gray reminds us that there is so much we do not know.  It tells us that, like it or not, we will live life in a mystery, a mystery in which we must learn to accept the inevitability of that which is unknown.
     If we really understand the fact of gray, we will understand the fact of God.
