Why , because is says the man of sin, the ac, is revealed first, but the one " letting" is holding the trib back. The one letting is holding back the revealing of the ac.
And that can't be the Holy Spirit, because He is omnipresent, like the other 2 members of the Trinity. And His primary ministry is evangelism and conviction. So He will be very active during the Trib.
Since it says "revealed", then the rapture, there is no postrib rapture anywhere in that dynamic
Actually, that IS the dynamic of a post trib rapture. The Trib and revealing of the a/c is revealed, and THEN the Second Coming and "gathering" (rapture) per v.1.
Postrib rapture is nowhere in the bible.
2 Thess 2:1-3 is very clear. But one must have open eyes to see it.
Zero verses pointing to it.
In fact, this applies directly to the pre trib theory. There are no verses that show Jesus taking resurrected and raptured believers to heaven.
It isn't even implied in any verse. But, of course, people are always "seeing things".
