I said that this group was taking a big gamble on this. If May 21, 2011 passes without incident, then they've lost ALL credibility. He said that he would be ready for Judgement Day when it comes and that it's best to be prepared. He had definitely made up his mind that this is happening. He would not entertain a counterfactual (or in this case, maybe just a factual).
I took his literature even though, or perhaps because, I thought this doomsday prediction was a little out of the ordinary. It has interesting math in it and some questionable stretches of the imagination (e.g. "In 2 Peter 3:8,...one day is as 1,000 years. Therefore, with the correct understanding that the seven days referred to in Genesis 7:4 can be understood as 7,000 years, we learn that when God told Noah there were seven days to escape worldwide destruction, He was also telling the world there would be exactly 7,000 years (one day is as 1,000 years) to escape the wrath of God...")
If you're curious about this, I would totally recommend checking out their site. I especially like the 2012 with a circled red slash through it, but there's such other gems as: Another Infallible Proof and Gay Pride: Sign of the End. I wonder if they'll have a radio show on May 22nd.
