1 Tessalonicenses 4

15 For this we say to you{} by the word of the Lord, that we who are alive, who are left to the coming of the Lord, will in no way precede those who have fallen asleep.

16 For the Lord himself will descend from heaven, with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ will rise first;

17 then we who are alive, who are left, will together with them be caught up in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.

18 Therefore comfort one another with these words.
