1 Tessalonicenses 4

15 For this we declare to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who have died.

16 With a shout of command, with the archangel's call, and with the sound of God's trumpet, the Lord himself will come down from heaven, and the dead in Christ will rise first.

17 Then we who are alive and remain will be caught up in the clouds together with them to meet the Lord in the air. And so we will be with the Lord forever.

18 So then, encourage one another with these words.
