According to 1 Thess. 4:16-17,
both the resurrected dead in Christ and those
alive meet Him in the air and not on the
ground. When His feet stand on the Mt. of
Olives, according to Zech. 14:3-5 the mount of
Olives splits in half, and all the saints
return with Him.
1 Thess. 4:16-17, "For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord."
Zechariah 14:3-5, "Then shall the LORD go forth, and fight against those
nations, as when he fought in the day of battle. And his feet shall stand in that day upon the
mount of Olives, which is before Jerusalem on the east, and the
mount of Olives shall cleave in the midst thereof
toward the east and toward
the west, and
there shall be a very great valley; and half of the
mountain shall remove toward the
north, and half of it toward
the south.
And ye shall flee to the valley of the
mountains; for the
valley of the
mountains shall reach unto Azal: yea, ye
shall flee, like as ye
fled from before the
earthquake in the days of Uzziah king of Judah: and the
LORD my God shall
come, and all the
saints with
thee."
