After extensive investigation I have managed to uncover the source of the rapture prophecy. In 2009 Terminator 'Salvation' was released on May 21st - starring Christian Bale and Sam Worthington. The video trailer for that movie clearly states that on May 21st "the end begins". This, I believe, is the source of the confusion, problem solved.
Regardless, if rapture does come, can one of you heathens please walk my dog and water my plants while I am gone?
Thanks from heaven. :-) Labels: Commentary, Rapture
