>> In one of Graham Greene's late novels, "Monsignor Quixote", the eponymous priest tells Sancho (of course) that he had the most horrible dream the night before. He says in his dream Jesus Christ returned to earth and proved incontrovertibly that he was who he said he was, the savior / god who Christians have held faith in ever since. The monsignor says this horrified him because he no longer felt a purpose in life.

I doubt that the priest needed to have despaired. I am sure that when Christ does return to earth He will reveal many things about God and the universe that will still require tremendous amounts of faith to accept.
