That was all I needed. I went away, thought about it, and applied to college. You don't have to believe in a literal heaven to get the point. I keep a small white stone on my desk to remind me of the same point. I am no biblical scholar, but I know what I think it means.
Life is a search for the white stone.
It will be a different one for each of us. It means, I suspect, passing life's little tests, until you are free to be fully yourself, which is when you get your white stone. The Greeks spoke of our daemon and the Romans of each person's genius. Jesus said the kingdom of God is within us. These ideas suggest that our soul is what drives us, if we can only get in touch with it.
