The radio preacher was ridiculed last year after he claimed the world would end on May 21, and then again on October 21.

Now, months after he admitted he was wrong and that the whole affair had been rather 'embarrassing', he has apologised again - but with the claim that his erroneous rapture predictions have worked wonders for Christianity's profile.
