1 Thessalonians 4:14-17

For if we believe that Jesus died and rose again, we also believe that God will bring with Jesus those who died while believing in him. This is the word of the Lord: we who are alive in him and remain until the Lord appears will by no means have an advantage over those who have already died, for both will rise together. For the Lord himself will appear with the declaration of victory, the shout of an archangel, and the trumpet blast of God. He will descend from the heavenly realm and command those who are dead in Christ to rise first. Then we who are alive will join them, transported together in clouds to have an encounter with the Lord in the air, and we will be forever joined with the Lord.
