1 Thessalonians 4:13-17

Now also we would not have you ignorant, brethren, about those who fall asleep [in death], that you may not grieve [for them] as the rest do who have no hope [beyond the grave]. For since we believe that Jesus died and rose again, even so God will also bring with Him through Jesus those who have fallen asleep [in death]. For this we declare to you by the Lord's [own] word, that we who are alive and remain until the coming of the Lord shall in no way precede [into His presence] or have any advantage at all over those who have previously fallen asleep [in Him in death]. For the Lord Himself will descend from heaven with a loud cry of summons, with the shout of an archangel, and with the blast of the trumpet of God. And those who have departed this life in Christ will rise first. Then we, the living ones who remain [on the earth], shall simultaneously be caught up along with [the resurrected dead] in the clouds to meet the Lord in the air; and so always (through the eternity of the eternities) we shall be with the Lord!
