What was once called good will be called bad and what was once called bad will be called good.
We’re there.
See if this sounds familiar (excerpt):
...The other path is described as Messiah coming "humble and riding upon a donkey" (Zechariah 9:9). In this scenario, nature will take its course, and society will undergo a slow painful deterioration, with much suffering. God's presence will be hidden, and his guidance will not be perceivable.According to this second path, there will be a valueless society in which religion will not only be chided, it will be used to promote immorality. Young people will not respect the old, and governments will become godless. This is why the Midrash says, "One third of the world's woes will come in the generation preceding the Messiah." (Rabbi Aryeh Kaplan, "Handbook of Jewish Thought")
According to the Talmud, as the Messianic era approaches, the world will experience greater and greater turmoil: Vast economic fluctuations, social rebellion, and widespread despair. The culmination will be a world war of immense proportion led by King Gog from the land of Magog. This will be a war the likes of which have not been seen before. This will be the ultimate war of good against evil, in which evil will be entirely obliterated. (Ezekiel ch. 38, 39; Zechariah 21:2, 14:23; Talmud – Sukkah 52, Sanhedrin 97, Sotah 49)
