SPOKANE, Wash. -

The end of the world is Saturday, according to California minister Harold Camping, who says his calculations, based on an intricate Biblical timeline, tells him that May 21, 2011 is the day the world comes to a screeching halt.

Matt Ivers believes it.

"I quit my job about two months ago," Ivers says. "I wanted to prepare and preach about it."

Ivers is a University of Idaho graduate, a smart man, and he says he's studied the Bible and he believes Camping's claims.

"Its really the Bible saying and declaring its May 21st," he says.

Ivers is now standing on Spokane street corners sharing the good news, or bad news, depending on how you look at it.

"There are two sides of this coin," Ivers says. "For the true believers its the rapture. We'll be caught up to meet God. For everyone else this will be a day of great destruction."

Friday evening there will be a great rolling earthquake across the Earth, Ivers says. "It ill be the biggest earthquake the world's ever known. Its gonna make Japan look like a walk in the park."

And if it doesn't happen? If he wakes up Sunday morning and everything is fine?

"I'm not even gonna answer that," he says. "It will happen."

And if it doesn't we'll call him Sunday morning.
