1 Thessalonians 4 - ESV

For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep.

For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. 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, and so we will always be with the Lord.
