Nah you're definitely misunderstanding the scripture. Paul says the gathering to Jesus occurs after the man of sin is revealed in 2 Thess. 2:1-4. Paul doesn't reverse his position on this at any point. You're failure to comprehend this ruins your exegesis of the scripture.
Yes, my point was the the 'restrainer being taken out of the way" prior to the great tribulation is most likely not the Holy Spirit since the Holy Spirit can be proven to still be present in saints during the great tribulation as I've already shown.
2 Thessalonians 2:7-9
7For the mystery of iniquity doth already work: only he who now letteth
will let, until he be taken out of the way.
8And 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:
9Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
The restrainer being taken out of the way, referred to as a he, is something that must happen before Jesus returns and destroys the anti-Christ. So it's something holding back God's wrath which comes after the great tribulation.
The 6th seal must be taken out of the way by Someone to open the scroll:
Revelation 6:16-17
16And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17For the great day of his wrath is come; and who shall be able to stand?
This corresponds to the 7th trumpet in Revelation 11:15-19 and 7th vial in Revelation 16:17-21 which are harbingers of the wrath of God against the anti-Christ at the return of Christ.
I don't suspect you'll be able to accept these truths, but in any case here they are anyway.
