1 Thessalonians 4:12-18

so that you will behave properly toward outsiders [exhibiting good character, personal integrity, and moral courage worthy of the respect of the outside world], and be dependent on no one and in need of nothing [be self-supporting]. Now we do not want you to be uninformed, believers, about those who are asleep [in death], so that you will not grieve [for them] as the others do who have no hope [beyond this present life]. 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 we say this to you by the Lord’s [own] word, that we who are still alive and remain until the coming of the Lord, will in no way precede [into His presence] those [believers] who have fallen asleep [in death]. 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. Then we who are alive and remain [on the earth] will simultaneously be caught up (raptured) together with them [the resurrected ones] in the clouds to meet the Lord in the air, and so we will always be with the Lord! [John 14:3; 1 Cor 15:52; 2 Cor 5:8; Phil 1:23; Col 3:4] Therefore comfort and encourage one another with these words [concerning our reunion with believers who have died].
