Rapture is Biblical

Here is an article by Joel C Rosenberg about the biblical fact of the rapture and why it will be before the Tribulation. It is the best one-stop shop defense of the doctrine I've seen.
I was shocked/not shocked to see that the new Left Behind movie released recently has sparked lots of rapture haters, from Christians no less, who fervently denounce this as a biblical doctrine at all! I am surmising from Mr Rosenberg's title that this is one reason he wrote the essay in defense. It is a good, fast apologetics course in itself and I thought this piece was one of the best Joel has done in a long time.
The essay explores the following subjects

• What exactly is “The Rapture”?
• Is “The Rapture” a Biblical concept, or merely a fictional plot device?
• What does the term mean?
• What are the implications of “The Rapture”?

"Hollywood tackles the End Times with “Left Behind” film. But is “The Rapture” a Biblical concept, or a fictional plot device?"
