Which particular books are your referring to?
I have read a few, which they say never reached the Bible.
One key point that arises is and of which I pickup as well from the Bible is - that the majority will be off the key core truths, re the basics of who and what the Father and Son are until Jesus comes and exposes the lies. 2 Thes 2 (not a 3rd Temple here, but the people)
The trouble is, the wrath follows, which is immediately after the tribulation imo, but the elect have already been gathered, just before Jesus's literal touch down.
So that suggests to me, they will have to cop the wrath and cling to this revealed truth.
Hence the woman (CC) drunk on their blood
, lol, never mind, God eventually wipes away their tears.
I hope I'm wrong, BUT??????
