1 Thessalonians 4:13-17
13 But we don't want you to be ignorant, brothers, concerning those who have fallen asleep, so that you don't grieve like the rest, who have no hope.
14 For if we believe that Jesus died and rose again, even so those who have fallen asleep in Jesus will God bring with him.
15 For this we tell 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 God's trumpet. The dead in Christ will rise first,
17 then we who are alive, who are left, will be caught up together with them in the clouds, to meet the Lord in the air. So we will be with the Lord forever.
