Its right there in the scripture you just posted:
>> “For that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of destruction” <<
.
Once you read that declaration, you have to make Paul a liar to believe that a rapture came before what he said had to first come.
I'll re-paste it here for you:
The Restrainer In 2 Thessalonians the Apostle Paul speaks of a "he" that will restrain the advent of the Antichrist. The restrainer's removal is required before the Antichrist can be revealed.
2 Thessalonians 2:6-8, "And now ye know what withholdeth that he might be revealed in his time. For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming."
A debate has erupted over the identity of the Restrainer because if this "he" is the Holy Ghost, the only real explanation for his removal would be the rapture of the Church, which is indwelled by him. The strongest argument offered against the Holy Spirit being the Restrainer is the belief that if God's Spirit was ever removed from the earth, no one could then be saved. The removal of the Holy Ghost does not have to be an all or nothing proposition. I believe his being "taken out of the way" will only be a degree of removal.
Before the Church Age, people were able to find salvation, which obviously meant the Holy Spirit was at work on earth. When the outpouring of the Holy Ghost occurred at Pentecost, we didn't have a second Holy Spirit come to earth. His removal at the rapture will only be a reversal or ending of the Pentecostal outpouring.
No it isn't.
2 Thessalonians 2:1 Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers and sisters, 2 not to become easily unsettled or alarmed by the teaching allegedly from us--whether by a prophecy or by word of mouth or by letter--asserting that the day of the Lord has already come.
The day of the Lord throughout scripture is talking about the tribulation period culminating in the battle of Armageddon. Paul knew they would think with the problems the Jews were going through that the "day of the Lord" was present and that they had missed the rapture. He goes on in verse three telling them that the rapture will happen before the "man of lawlessness is revealed".
Rather than be afraid the tribulation had already started they should know that it cannot start until the "departure" comes. Then the "man of lawlessness" will be revealed.
2 Thessalonians2:3 Don't let anyone deceive you in any way, for that day will not come until the departure occurs and the man of lawlessness is revealed, the man doomed to destruction.
So he was telling them not to worry that the day of the Lord (the tribulation period) had already begun because the "catching up" or "departure" or "rapture" had to happen before that could happen.
