1 Thessalonians 4:14-16

14For we believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him. 15According to the Lord’s word, we tell you that we who are still alive, who are left until the coming of the Lord, will certainly not precede those who have fallen asleep. 16For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first.
