World wars, and all the other parts of Jesus sign that identity his parausia correspond with 1914 and all the events that followed and the preaching work is all evidence that this is the time period that Jesus prophesied about. Therefore the great tribulation must come during this era of the anointed of the JW. Only the great tribulation with the tethered immediate events has not occurred yet. So seeing all the other evidence, the the gt will hit shortly.
As I said before everybody that was alive in 1914 is gone now both righteous wicked and anointed. Given all the other fulfilled parts the the prophecy, the passing away can only refer to the overlap. Which means that evil generation is not the meaning of generation today.
