That was quite the edit haha.
I guess I need to clarify. There aren't 2 separate classes in the sense that I was taught, or how you seem to portray, imo. I'm not saying either of us are right.
But I'll only say this regarding the "great crowd", as you have your own thread on the subject. So I won't comment on it further after this:
After reading your AI produced script I did agreed that "careful interpretation" is required. Thus we need all the facts. I can't help but notice that Revelation 19:1 and 6-8 were never mentioned by you or the AI, anywhere.
Rev. 19:1 "After this I heard what sounded like the roar of a great multitude IN HEAVEN shouting:
Salvation and glory and power belong to our God,"
And 6-8: "Then I heard what sounded like a great multitude, like the roar of rushing waters and like loud peals of thunder, shouting: “Hallelujah! For our Lord God Almighty reigns.
Let us rejoice and be glad and give him glory!
For the wedding of the Lamb has come,
and his bride has made herself ready.
Fine linen, bright and clean,was given her to wear.”
(These in my opinion are the wedding guests, and they have either died loyal during, or lived through the tribulation, see the letter the Church of Laodicea. The Church of Philadelphia letter is referencing the 144K) The letters order coincides with future events.
"in" : Strong's Greek 1722
All occurrences denote exactly the same meaning or connotation. The very same we're all familiar with. Across a multitude of translations, they all translate it the same. It's a simple word to determine. There were other words available to the writer at the time. If the Spirit wanted a different a meaning than "in" to be understood by us, then it would have been written accordingly. He is not a God of confusion. Good candidates or clear options are " ἔμπροσθεν " or " ἐνώπιον ". I encourage you to do a word study if this still isn't clear to you.
Again, to say otherwise or apply a different meaning would be countering the Bible AND dangerous. -Revelation 22:18,19
The Great Crowd are invited to the wedding feast in Heaven. So yes, two "classes" but with different outcomes based on how they live or accept Christ. The wedding occurs in Heaven.
This article makes things pretty clear:
It's long and detailed, but exhaustive on the subject. I encourage you to read it.
