someone's really creative imagination.

Supporters for this belief generally cite the following primary sources in the New Testament:
Then there will be two men in the field; one will be taken and one will be left. Two women will be grinding at the mill; one will be taken and one will be left. (Matthew 24:40-41)
John 14:1-3
In 1 Corinthians 15:51-52, the Apostle Paul writes: "Behold, I show you a mystery; We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed."
In 1 Thessalonians 4:13-18, Paul writes: "For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we who are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord."
In Philippians 3:20-21, Paul writes: "For our conversation is in heaven; from where also we look for the Saviour, the Lord Jesus Christ: Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself."
Generally, an elaborate set of predictions about the end times are constructed from these sets of verses, together with various interpretations of the Book of Revelation and the predictions of Christ's return in Matthew 24:30-36.
In general, believers in the rapture consider the present to be the end times, and offer interpretations of the various symbolisms in the book of Revelation in terms of contemporary world events.++++++++++++++++++
I mean this is almost as silly as the idiots who actually think the 'Men lying down with Men' was actually about homosexuality but still haven't grasp the concept that eating at Red Lobster is a sin in the eyes of God (creatures from the sea without fins is an abomination - it's all from Leviticus)
Seriously, I'm a Christian and even I have a problem with all of this
