Now, brothers, concerning the coming of our Lord Jesus Christ, and our gathering together to him, we ask you
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 (1 Thessalonians 4:16-17).
