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 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.
