1 Thessalonians 4:13-16

Now we do not want you to be uninformed, believers, about those who are asleep [in death], so that you will not grieve [for them] as the others do who have no hope [beyond this present life]. 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.
