The bane of "Rapture" and "Left Behind" fear mongering is upon us once again in the form of a movie re-make. According to proponents of this misguided view, when Jesus comes again the "good" people will be instantly sucked up / transported into the heaven (in the air) leaving the "bad" people to suffer years of torment... until the final judgment day. However, In the Gospels we encounter a Jesus who says he is like a shepherd who goes in search of even one lost sheep, or like a woman searching for a lost coin... never resting until all are accounted for. Jesus doesn't leave anyone behind!
The following article from Biblical Archaeology Review provides some history on the erroneous "left behind" theology, and does a good job of discrediting it. Another excellent resource is Professor Barbara Lundsblad's book, "The Rapture Exposed" which is available through Amazon.
