Correct and He will shorten the time - but the elect during the Tribulation is distinct from The Church. Almost all of the verses you lay out are directed toward the Jewish Nation.

Oh brother. Another rapture by December thread. You realize that ‘rapture by December’ has been predicted countless times for 2000 years right?
Yours is the first “somewhat understandable” position on a pre Trib rapture for me. However, my doubts about it would not disqualify me from partaking, if it was to occur.
I imagine the book of Daniel would reveal the truth or falsehood of a pre Trib rapture, as the Lord always confirms His Word by His Word.
