Scriptures better describes a Mid-trib Rapture, then either a pre or post-trib. There are 7 seals that are opened, then 7 Trumpets that are blown, then 7 vials/bowels that are poured out. At the 7th Trumpet sounding is the Day of the Lord, the Rapture, the Return of Jesus Christ, Dead raised, living Christians raised, Unsaved left behind.
Now pay attention here, what else happens at the 7th Trumpet blowing?
Rev 11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever. 16.. .. . .17 .. . .. .18. .. . .19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
When is the Temple of God opened? At the 7th Trumpet sounding. What comes out of the Temple of God?
Rev_15:6 And the seven angels came out of the temple, having the seven plagues, clothed in pure and white linen, and having their breasts girded with golden girdles. 7 . . . 8 And the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues of the seven angels were fulfilled.
Rev_16:1 And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the vials of the wrath of God upon the earth.
So Scriptures plainly and clearly reveals that at the 7th Trumpet is when the Temple of God is opened, and AFTER the 7th Trumpet sounds, is when the 7 Angels will pour out the seven plagues upon men on the EARTH, those men which were not taken up in the Rapture at the 7th Trumpet sounding.
Plainly and clearly the Scriptures reveals that there are 7 seals, 7 trumpets, and 7 plagues. Christ Returns at the 7th Trumpet to the Earth and sets up His Kingdom on the Earth, even as
Zechariah 14 teaches, then AFTER the Rapture, those who are left behind will experience the 7 last plagues which is most certainly a part of the Tribulation Period. Jesus Christ Returns and Raptures the Church MID-TRIB according to plain Scriptures and what they plainly teach for all to see. The interpretations of humans corrupt plain Scriptures.
