Speculation!
Cults feed on speculation, they are always coming up with dates, events and what their leader-leaders said? They are manipulators of peoples vulnerability and also on how to build up and tear down ones hopes!
The bible is very clear on the matter of the end of this world, as to dates only the Father knows, not even Jesus!
Events will occur in Jerusalem, Israel and these will lead to the false Messiah arriving on the scene!
Acts 1:6-11, Matthew 24:30, 25:31, 1 Thessalonians 4:10, Revelation 1:7.
Ask me and I will tell you!
