1 Thessalonians 4:13-18

And we do not want you to be ignorant, brothers, concerning those who are sleeping, so as not to be sorrowful, like these others who do not have hope. For if we believe that Jesus has died and risen again, so also will God bring back with Jesus those who sleep in him. For we say this to you, in the Word of the Lord: that we who are alive, who remain until the return of the Lord, will not precede those who have fallen asleep. For the Lord himself, with a command and with the voice of an Archangel and with a trumpet of God, shall descend from heaven. And the dead, who are in Christ, shall rise up first. Next, we who are alive, who are remaining, shall be taken up quickly together with them into the clouds to meet Christ in the air. And in this way, we shall be with the Lord always. Therefore, console one another with these words.
