Regarding the quote by “leaving_quietly” mentioned above, “So, the tribulation does not culminate in Armageddon, according to Jesus. Right AFTER the tribulation, is when signs in heaven will be and when the "second coming" occurs,” that could not be correct. A correct rendering of that would read: “Right AFTER that specific part of the tribulation, . . .”; i.e., right after that initial phase of the Great Tribulation when Babyon the Great is to be turned on. The Great Tribulation refers to the whole thing – including Armageddon as the very last part of it.
Yes, this is what WT teaches.
how can Armageddon, with it's promised >7 million survivors, and that at least will spare the animal/birds,-- not be included in it?
Good question.
This is a difficult subject to truly understand as most of us have a one-sided of what Armageddon is. According to Revelation 16:13-16, Armageddon is a PLACE where the kings of the earth (and presumably their armies) are gathered together for the war against God's armies. There is no mention here of non-military people. Rev 19:19-21 seems to be a description of this same event, where again, it's the kings of the earth, and their armies.
The question is, is Armageddon the event that WT makes it out to be? As I read these verses just now, it seems to me it's the ultimate fulfillment of Daniel 2:44, the part where it says of God's kingdom, "It will crush and put an end to all these kingdoms."
Noteworthy is Rev 16:15, an interjection, right before talking about Armageddon: "“Look! I am coming as a thief. Happy is the one who stays awake and keeps his outer garments, so that he may not walk naked and people look upon his shamefulness.”"
This seems to imply that it happens BEFORE Christ's second coming, or perhaps as part of it.
So, I don't know myself. I only know what WT teaches. Whether Armageddon is part of the great tribulation or not and whether it involved everyone or not, I simply don't know. Part of me says no. Part of me says yes. It's one of those topics that I'll have to mark: "inconclusive". For now, at least.
