1 Thessalonians 4:14-16

For if we believe that Jesus died and rose again [as in fact He did], even so God [in this same way—by raising them from the dead] will bring with Him those [believers] who have fallen asleep in Jesus. For we say this to you by the Lord’s [own] word, that we who are still alive and remain until the coming of the Lord, will in no way precede [into His presence] those [believers] who have fallen asleep [in death]. For the Lord Himself will come down from heaven with a shout of command, with the voice of the archangel and with the [blast of the] trumpet of God, and the dead in Christ will rise first.
