1 Tessalonicenses 4

15 Besides, this we affirm to you, by the word of the Lord, that we, the living, who remain at the coming of the Lord, shall not anticipate them who are asleep:

16 for the Lord himself will descend from heaven, with a shout, with the voice of the Arch Angel, and with the trumpet of God. And the dead in Christ shall rise first;

17 afterward we, the living, who remain, shall, at the same time with them, be instantly taken up in clouds, to join the Lord in the air; and so we shall be for ever with the Lord.

18 Wherefore, comfort one another with these words.
