1 Thessalonians 4:16-17

For the Lord himself, with a command and with the voice of an Archangel and with a trumpet of God, shall descend from heaven. And the dead, who are in Christ, shall rise up first. Next, we who are alive, who are remaining, shall be taken up quickly together with them into the clouds to meet Christ in the air. And in this way, we shall be with the Lord always.
