Its a shame someone who's lived as long as Mr Camping doesn't realize that.
Perhaps Mr. Camping, despite being a preacher for so long, is trying to store up treasure on Earth instead of in Heaven. He wants to be remembered as the prophet who correctly deciphered the Rapture. Yet, if he truly predicted it there would be no one to appreciate his prediction. Let's just assume he is senile and has been for a while, since he has predicted this before and now yet again for Oct. 21.
