Won't most rank & file say there is no change?
Basically they are thinking that at least one person of the anointed who is last sealed into the kingdom would be alive at the time of the "great tribulation" and Armageddon, so that fulfills it and allows to extend past the Biblical-based "generation" of either 40 or 80 years.
But on this point it's a moot point anyway. That's because the Bible clearly says the tribulation is completely over before the "sign of the son of man" appears. "Immediately AFTER the tribulation of those days....". JWs absolutely need for this to mean, "Immediately after the beginning of the tribulation.." Thus those who see the "sign of the son of man" are those who see it at the last minute during Armageddon. Fine. But the Bible doesn't say that. It says AFTER the tribulation, meaning it is over. If the tribulation is "Armageddon" then this happens AFTER Armageddon. That means the second coming is AFTER Armageddon. It doesn't work. This error thus is more significant than an expanded concept of the "last generation."
But this in no way means the Bible is not true, That's because, in this case, the "great tribulation" is not Armageddon but is talking about WWII and the HOLOCAUST. This is when the Jews are almost completely exterminated and the "days had to be cut short or else no FLESH would be saved." This is talking about the flesh of the natural Jews, two-thirds of whom were wiped out during WII (but as prophesied at Zech 13:8). Thus once the Holocaust is over then they would start seeing the sign of the son of man appear. Incidentally all this happens within a 40-year generation from 1914-1954. So they are clueless totally and in total spiritual darkness as was also prophesied. They have no holy spirit to understand the truth now. So they will end up with one false teaching after another.
But we doe see some renewed focus here, some increased activity with respect to the organization with the new JW-Only magazine. Thus it will be fulfilled that when they are destroyed along with BTG it will be when they are "still alive", meaning, still an active and viable organization for all intents and purposes, thus with many current believers.
