While something may be probable, that something doesn’t make it certain or knowable. He said his coming would not be knowable, even if it occurs before OR after the peace treaty! Christ always said things or did things that people would not always expect, yet when checked...did fulfill scripture(but not in ways we “experts”/s might have expected). He comes as a thief...remember?! Like Nineveh, Christ still wants to save souls...so should he tarry a few extra milli”seconds” of eternity,it doesn’t mean he won’t eventually carry out his plans!
We can only know the nearness of his coming, the “season” of it...that’s the best we have been given!
Some believe that snatching away will happen mid-trib. There is a strong case to be made and made by scholars more wise than us, that the Bride will be removed before the Man of Sin emerges to make treaty with Israel of a seven year compact. It may be related to the Psalm 83 war, which will be between Ishmael descendant Islam and Israel. The war that is titled 'armageddon' is between Israel and gog and magog, not Ishmael descendant Islamic powers.
Saving souls will continue during the Tribulation. The Holy Spirit indwelling will no longer be happening since that is a characteristic of the Bride being prepared for The Bridegroom, but He will be putting the HS seal on untold millions who bow their knee during the Tribulation.
The number of days after that peace treaty is signed are specifically stated in Daniels prophecies.
