okIt means that the elect are gathered at the second coming which is after the tribulation, just as the Bible says.
I see no reason why these can't be 2 separate events:Why are those who are left still remain until the coming of the Lord? If your answer has anything to do with the rapture, you're reading your assumption into the text. Those who are left are left because they're still living. Unlike the rapture, that is in the text; no assumptions required. Also, if those who are "left behind" are those who haven't received salvation, why is Paul including himself (we who are alive) and addressing this to a church?
The tribulation is going to be a time of unprecedented trouble, and those who are expecting to not go through it will not be ready for it. There are people who put so much faith in their doctrines that they really don't care what the Bible really says, just as long as they can use it to support what they believe.
It's no wonder that this doctrine seems to thrive in the western church...
1 Thessalonians 4:16-17 (ESV)
[sup]16 [/sup]For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. [sup]17 [/sup]Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord.
Zechariah 14:3-4 (ESV)
[sup]3 [/sup]Then the Lord will go out and fight against those nations as when he fights on a day of battle. [sup]4 [/sup]On that day his feet shall stand on the Mount of Olives that lies before Jerusalem on the east, and the Mount of Olives shall be split in two from east to west by a very wide valley, so that one half of the Mount shall move northward, and the other half southward.
I see no reason whatsoever to believe that salvation is dependent upon believing one way or the other.
