Consequently, in addition to what Jude 7 says, the Bible uses Sodom/Gomorrah and the Flood as patterns for the destructive end of the present wicked system. It is apparent, then, that those whom God executed in those past judgments experienced irreversible destruction. Of course, each of us can confirm that by his proving faithful to Jehovah now. In that way we will qualify to be alive in the new world to see whom he resurrects and whom he does not. We know that his judgments are perfect. Elihu assured us: “For a fact, God himself does not act wickedly, and the Almighty himself does not pervert judgment.”—Job 34:10, 12.
So 1988 - Maybe1989 - NO
I thought that the latest change indicated that we do not know and will have to wait and see. Maybe something more recent.
