Something I find a little disturbing are a few posts in which people would seem to take a little joy in "being right" if there were no pre-trib rapture. That's just a little odd to me - hell would be breaking out, and some people would be going around saying "Na na na boo boo, I was right!"??
Here are the main verses I use to defend pre-trib rapture:
2 Thess 2:
1 Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, 2not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. 3Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, 4who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
5Do you not remember that when I was still with you I told you these things? 6And now you know what is restraining, that he may be revealed in his own time. 7For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way. 8And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.
To me, these verses can't mean anything but pre-trib rapture..
There are 2 different events being talked about here. Verse 1-4 tells us that the Lord's second coming cannot happen until after the lawless one is revealed, then verses 6 through 8 tell us that the lawless one will not be revealed until "he that restrains is taken away". So, who is he that restrains? Who else can it be but one of the following 2:
(1)The Church (this means a pre-trib rapture)
(2)The Holy Spirit (pre-trib rapture, also, because if the Holy Spirit were to leave us, we would drop dead-we cannot live without the Holy Spirit. The old nature was crucified with Christ and replaced with a new nature, the nature of Christ. We are "partakers of the divine nature". If the Holy Spirit left, our flesh would die. "For in Him we live and breathe and have our being."---Acts 17:28
So here's the sequence of events I get from those verses in 2 Thess:
Church taken away
Lawless One revealed and commits acts of horror
Christ returns triumphantly (second coming)
