Is that what your idol, Rood, has taught you? That is definitely NOT what Paul communicated to the Thessalonian believers. But I see why you would latch onto that error so firmly, given the teachings of Michael Rood.
What Paul wrote is that those believers could not yet be in the tribulation of The Day of The Lord because things he had taught them would precede The Day of The Lord Tribulation had not happened, so they could not be in that Day yet:
2Thess2:1 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. 3 Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction.
This will fall on your deaf eyes but I will state it anyway, for others reading along. Paul just conveyed that these believers should not be confused by some teaching that is not from him. He had taught them about the Rapture (as reinforced in the first letter 1Thess$:13-18). He had reassured them that some believers who had died after he taught them were not left behind, and wrote that they should comfort one another with this knowledge conveyed. (I'm paraphrasing for others, not to confuse you ES).
Something arrived that threw them back into confusion, confused about the Day of The Lord which was to come upon those not taken in the Rapture. To reinforce that they had not missed the Rapture and were thus now in The Day of The Lord, He reminded them of what will happen showing the arrival of The Day of The Lord.
They had not been taught to watch for the anti-Christ but to watch and wait for the snatching away so that they would not be going through The Day of The Lord under antichrist.
The pre-trib rapture is the error.
Paul’s words to the Thessalonians are unmistakable.
The falling away and the man of sin must come first.
.
Also it must be noted that Yeshua clearly stated that our redemption will come “after the tribulation of those days.”
All scripture points to a first resurrection after Satan’s tribulation of the saints.
