"Will the judge of all the earth not do what is right?" IF you know for sure that God is your friend, then what are you worried about? Salvation does not depend on interpretation of the Bible but on God who closes the door.
According to JW, the destruction of BTG also results in the deaths of people who did not get out of Ur (her) and get stuck inside Jerusalem when Titus encircles her during the gt. JWS will escape because they catch sight and flee to safety before it happens. According to Josephus, many clever Jews abandoned Jerusalem like rats from a sinking ship (along with Christians) because they knew that the Romans would be back. JW also have taught in the past that some jws could also get killed during the gt but would be resurrected later. And same as the the clever Jews that fled Jerusalem after Gallus (according to Josephus) clever ones to will escape BTG destruction. But D day is Armageddon. If God executes you at Armageddon then you are going to the other place and not coming back. But ultimately, God is the final judge.
It was only when Pharaoh went after to kill the Jews that God was forced to act to protect them and save them, as was also the case during ancient Israel's existence as a nation, He often had to step in as their God to protect them and to deliver them.. When God's enemies attack his people at Armageddon, He will be forced to act to protect them. At some point truth will hit the mind's eye of the spiritually blind and they will finally see and hear, thus realizing empirically that it is no coincidence. But God will kill his enemies, if you are his friend, relax, don't worry, you have nothing to worry about. If you do not believe in God or the Bible or in anything more than the physical science, you are going to die anyway, so why worry. Like the dead Issac Asimov. He is dead and and so is his dead philosophy. I would be very interested in hearing about the chance or hope of life after death, but everybody knows that everybody dies sooner or later. Don't need IA to teach me that.
JWS are not afraid of the teachings of other religions. Why should anyone be worried about JW warnings and preaching and teachings if they have nothing to fear? WT teaching about God destroying all religions is clear and has not changed.
