Another Doomsday has come and gone, making those who believed in Camping's vision feeling rather dejected afterward. Fortunately, there's Leon Festinger's classic book, When Prophecy Fails , to help guide these perplexed Christians through another day. What was intriguing to me is Camping believed only 200 million souls would be called up to heaven, leaving approximately 1,8 billion Christians behind, not to mention countless other lost souls. I guess only born-again Christians need apply.
