Second Coming will be known.
7 years after the Peace covenant is confirmed (how ever that happens).
Thief in the night is unknown. Pre-trib like me believes it’s just before that 7 years.
When the 7 years start, things really change rapidly. Middle of those 7 false prophet enforces that Mark of the Beast.
It seems like things are happening rapidly now. Wars and rumors of wars, famine, pestilence etc...sounds like present times, heh?
