1 Thessalonians 4:15
For this we declare to you by a word of the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep — the 'word of the Lord' (logos kyriou) may allude to a logion of the risen Jesus or a revelation to Paul; it carries apostolic authority. The living will not arrive at the parousia before the dead; God's justice ensures they are gathered simultaneously.
