I would actually allow for hyperbole by Jesus here. Also this was and OT way of talking about events such as these taken from Exodus.
Much OT prophecy, including Jesus's (until the death of the Testator), referenced 70A.D.
Matthee 24 is unique, in that it falls under this division:
Mar 4:34
34 But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples.
Mat 24:3
3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?
They asked about the sign of His Coming, and He specifically gave a timetable to the officers of His Church.
Mat 24:29-31
29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30 And then shall appear the sign of the Son of man in heaven:and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Now what this doesnt settle is MT/PostT.
Daniel says this:
Dan 12:12
12 Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
Which puts the end of the elect's participation (tribulation) at 2&1/2 months after the 3&1/2 year mark.
If we call this the end of 'The Great Tribulation', and the beginning of the 'Day of Wrath', then Mid Trib/Post Trib become the same basic teaching.
So, yes there is plain Scriptural evidence, no PHD needed, for Mid/Post.
As for Pre....much contortion is needed, to fit in that box.
A Mil., requires a disregard for face value in prophecy.
It takes less contortion, simply because so little plain teaching addresses the Mil.
But Rev. 20 seems to be too clear to ignore.
This is a quick summary on my part.
And I know of not one single Baptist Creed or Confession that includes drawing a line over eschatology...so I dont.
