I think it 'could' be related to that. But a few things which seem to contradict in the bible about this. When Jesus left earth, he floated up, and told his disciples he would return the same way he leaves, which seems to say that he would be seen desceneding out of heaven for the battle.
I don't think I need to quote them, but tons of scriptures about him and his father making their abode inside the elect, and that the elect are the temple. Then Jesus said he would 'be with his disciples UNTIL the great tribulation'. In connecting those dots, it seems his return on earth could be within all the true elect, as they are 'in union' with him, and their personalities are changed. Then he is withdrawn at the great tribulation because he is then physically coming to earth.
Anyway, appreciate your responses, as I do more research and reading, if what you say is true it will be revealed and/or in agreement with the holy spirit and scriptures I'm reading. Or both of our understandings are the beginning of the light getting brighter and may be somewhat of a combination of both. I believe this is what is spoken about in not forsaking the gathering of yourselves together and in accurate knowledge because true christians had group studies and they commented based on what they got from the scriptures and if everyone got the same thing, then it would feel overwhelmingly true, and if not all in agreement, going by their conscience. The unified part were the core basics of the truth, the undisputable truth which would have no varying.
Unfortunately, instead of each congregation having study and getting knowledge by comparing what they seem to be getting from holy spirit and understanding to increase knowledge, ALL of the understanding and knowledge is based off of 8 men who probably barely have time to read the bible and study, and probably never have time for deep bible discussion.
