The popularization of the term "Rapture" is associated with the teaching of John Nelson Darby, prominent among the Plymouth Brethren, and the rise of premillennialism and dispensationalism in English-speaking churches at the end of the 19th century. In 1908, the doctrine of the rapture was further popularized by an evangelist named William Eugene Blackstone, whose book, Jesus is Coming, sold more than one million copies. The first known theological use of the word "rapture" in print occurs with the Scofield Reference Bible of 1909. -Wikipedia
I've seen these people for years in the Times Square Subway tunnel wolk thru's. I've talked to one of them just about a month ago asking him what happens on May 22nd if they are still here. He said he couldn't answer that because that would be doubting his faith. It will be interesting to see if any of them take their lives or some other crazy action. Remember the Jehovah Witnesses said the same thing back in 1975 and for years they had to put up with the laughter and snide comments made at them.
I'm still rooting for the Mayans!
