Looking at the video mentioned in the last letter.......David Flynn, 'Key of David Rapture'  I noticed other videos on youTube stating that the Rapture will happen on 21 May 2011, but I did not hear where in the Bible it gives the date.  Can anyone enlighten me please, as to what book, chapter and verse it mentions this date? I did not watch all the way through each one so may have missed the reference.

Thank you.
