That was in response to your quote
"This can become quite a complex discussion involving the
comparison of (Matt. 24-25) with (Luke 21)."
In Matt 24:15 it already was talking about the abomination. Therefore the stuff after this seems to be after that time of the abomination of desolation.
There are probably billions of new believers in the last seven years. Even the unbelievers should get the message of the judgments as the idea is to get them to repent.
As stated, they may not see us going up, or Jesus in the air. They might see something though, in the sky happening.
I think most preachers I have heard place the timing of the Rapture to just before the judgments. Sort of like a king recalling His diplomats before a war.
That would mean that it would be near the time of the beginning of sorrows. That would also mean that the signs indicating the beginning of sorrows (I listed the five signs already from the three gospels) would also be indicating the Rapture was near.
