There is no rapture of the Church. What is called "rapture" is not a departure to heaven, but on the contrary, an aliyah to the Lord in Israel of the "five wise virgins".
Because we are now ALREADY living in heaven, if we are in Christ:
And hath raised us up together, and made us sit together in heavenly places in Christ Jesus: (Ephesians 2:6)
First the Lord must come down from heaven to earth:
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: (1 Thessalonians 4:16)
The Lord will come down from heaven to the land of Israel and remain here forever. The moment of His Second Coming is described in the Bible:
Then said the Lord unto me; This gate shall be shut, it shall not be opened, and no man shall enter in by it; because the Lord, the God of Israel, hath entered in by it, therefore it shall be shut. (Ezekiel 44:2)
The "glory of the Lord," the "chosen from the four winds," aka the "Philadelphian Church" of Revelation, "the full number of the Gentiles," will enter the eastern gate of the Temple. They will enter the gate until the day of Yom Kippur. When the eastern gate closes, it will be that very "twinkling of an eye" when the status of the people who entered these gates will change: they will become the incarnation of Jesus Christ at the Second Coming.
After this, we must wait for the "resurrection of the dead", the Jewish people must come to life, returning to faith in God. When the Israelites receive the saints who entered the eastern gate, as they were supposed to receive Jesus at the First Coming, this will open the way for the aliyah to Israel of the remaining 5 churches of Revelation, but not all believers, but only the "wise virgins". This will be the "rapture of the Church".
"Clouds" means "multitude of people," as in Hebrews 12:1. "Air" means the socio-political atmosphere of this world, as in Ephesians 2:2. Everything will happen in this world, before everyone's eyes. The result of aliyah will be the emergence of the city of Yahweh Shammah in Israel, where the resurrected tribes of Israel will work. The emergence of this city, where they do not work for money, and not under the supervision of rabbis or bishops, where they will work voluntarily for the glory of God, will change the atmosphere of this world. The 7th bowl of wrath, poured "upon the air," will change the socio-political atmosphere of this world. Instead of the prince of the power of the air, the spirit of Christ will rule in this world.
