1 Thessalonians 4:16-17

For the Lord himselfe shall descende from heauen with a shoute, and with the voyce of the Archangel, and with the trumpet of God: and the dead in Christ shall rise first:

Then shall we which liue and remaine, be caught vp with them also in the clouds, to meete the Lord in the ayre: and so shall we euer be with the Lord.
