The quote you gave of Zech.14:4, as you said, happens at the 7th trump when He returns. Please go to:
Zech.13:8-9
8.And it shall come to pass, that in all the land, saith the LORD, two parts therein shall be cut off and die; but the third shall be left therein.
(that is die a spiritual death because they follow anti-christ)
9.And I will bring the third part through the fire,and will refine them as silver is refined, and will try them as gold is tried: they shall call on My name, and I will hear them: I will say, It is My People: and they shall say" the LORD is my God.'
(we will go through tough times, we will be refined)
"Paul is just giving the order of of the calling of the church when the Lord returns first. The Lord does not come down to earth at this time but His church meets Him in the clouds"
"The quote you gave of Zech.14:4, as you said, happens at the 7th trump when He returns" No, what I said was, "gives the picture of the Lord's return described in Rev. 19 and 20, at the end of the tribulation period and the beginning of the millennium". This would happen after Rev. 16:17, "And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done." There is no more mercy or grace to be given to the unbeliever; for them it is judgment and the fearful coming of the King of King and Lord of Lords with His hosts. That happens after the last vial of His wrath is poured out.
Now, the trumpet judgments and the vial judgments all take place during the period of the last seal judgment, but they are distinct and increasing in intensity and accelerating in quickness of the wrath of God.
The marriage entourage comes to gather the Bride and her 'court', then the entire entourage returns to the marriage feast location. The return of Christ where He touches down on Earth is well after the marriage feast and is the final pouring out of wrath to cleanse the Earth for His kingdom. The King and his Bride reign in that day. I THESS 4 is about the coming for the Bride, other passages address the return to set foot upon the mountain. ... And this back and forth which grows to look like haranguing is why I don't get into pre-post trib debates, so I shall refrain from further posts in an exchange. Thank you.
