With respect, I haven't seen Him yet.
I've "seen" Him, but not coming in the clouds.
I don't see this as having happened yet, and I also do not see many of the events that are supposed to happen, like the beast, the false prophet and the 3.5 years of tribulation, as having happened yet, either.
Finally, I don't see the thousand year reign of Christ on His father David's throne from Jerusalem as having come to pass.
When you can show me, from history, that
all of the events of Matthew 24 have come to pass, literally, then I will believe that the first resurrection is
also passed and that we are are now in the 1,000 year reign.
But, since He is not ruling from Jerusalem and the saints are not ruling with Him ( 1 Timothy 2:12 ), then it's still to come.
May God bless you sir.
