We’ know when it's going to happen when the abomination stands on the mercy seat of the Ark. From then onward all things are on a time table.
Until it happens we just watch for prophesied events.
Revelation 3:
[3] Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
The penalty for not watching is rather severe!

In post 126 you said there would be a new earthly kingdom for 1000 years. Is this Israel or not?
