(and other “End of World” Timeline Prophesies)
This one is easily handled: any group that is making End of World Prophesies, giving dates, etc., is not a Christian group. Period. Scripture is clear that God, and only God alone, knows the date of the Day of Judgment. When you see end of world prophesies, or even other claims about books inspired by secret new revelations from God that someone has had, run as fast and as far away from that group as you can. They are of the devil, not of the Lord. Scripture, and all prophesy, was finalized and sealed long ago now. Also, as is common, when you see this false teaching, there will be other false teachings lurking with it.
