1 Thessalonians 4:15–17

15 What we tell you now is the Lord’s own message. We who are living when the Lord comes again will not go before those who have already died. 16 The Lord himself will come down from heaven with a loud command, with the voice of the archangel, and with the trumpet call of God. And those who have died believing in Christ will rise first. 17 After that, we who are still alive will be gathered up with them in the clouds to meet the Lord in the air. And we will be with the Lord forever.
