"for survival ... they have to remain organized with the anointed remnant, the 'chosen ones'
That applies to JW. JW teaches a blanket protection to JW as a group. Individual JW that don’t follow direction may get trapped inside the encirclement of the “Roman armies.” That is one aspect of survival that applies to JW. Of course, non JW that do not have that spiritual protection that comes from following direction ( according to JW) are in the same danger zone. So, JW believe that there is a divine protection over those that are JW. How everything actually plays out, JW don’t say they know. What JW assert, is that in a blanket sort of way, JW is the road to life.
It was once believed that the preaching work separated the sheep and goats and that made a lot of sense if the preaching work had any relevance towards salvation. One material for judgement was the response to the good news.
Now, the preaching work has the same value but the separation and judgement is later on.
Also have to factor in JW belief that BTG will be destroyed and there will be a vindication of JW religion. Fighters against JW = fighting God’s holy spirit ( as jw see it) and those found fighters won’t be saved. So pretty much people that reject and fight JW won’t be saved. But there are other people that fall into special situations and God is the judge of that. Ultimately God is the final judge. Pharisees in JC day were thrown into Gehenna only for “wicked” speech according to Jesus. So the same judgement can be expected at Armageddon.
Again , all this is interpretation. And we @JW believe, and it makes a lot of sense but as the article admitted: We just don’t know who will individually
survive Armageddon . JW do assert and believe and proclaim that JW as a group will survive.
There seems to be a distinction between Armageddon and Judgement day. I suppose that Armageddon encompasses judgement of the living but it ain’t over until after the Millennium.
