He does not come before the millennium, only after. So there are not two returns, only one. We just disagree on the timing, that's all.
Twice, for sure.
One time in the air among the clouds;
Rev. 14:14-16 (KJV)
And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle. [15] And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe. [16] And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
Which is the same thing as;
1 Thes. 4:16-17 (KJV)
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: [17] 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.
AND then again, when He actually returns to the surface of the planet.
Rev. 19:11-16 (KJV)
And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. [12] His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. [13] And he was clothed with a vesture dipped in blood: and his name is called The Word of God. [14] And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean. [15] And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. [16] And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
Which is the same thing as;
Zech. 14:3-4 (KJV)
Then shall the Lord go forth, and fight against those nations, as when he fought in the day of battle.
[4] 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.
Which is most likely this also;
Rev. 14:17-20 (KJV)
And another angel came out of the temple which is in heaven, he also having a sharp sickle. [18] And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe. [19] And the angel thrust in his sickle into the earth, and gathered the vine of the earth, and cast it into the great winepress of the wrath of God. [20] And the winepress was trodden without the city, and blood came out of the winepress, even unto the horse bridles, by the space of a thousand and six hundred furlongs.
TWICE for sure.
Love,
His servant
