1st Thessalonians 4:14

11 And that you may take pride in being quiet and doing your business, working with your hands as we gave you orders;

12 That you may be respected by those who are outside, and may have need of nothing.

13 But it is our desire, brothers, that you may be certain about those who are sleeping; so that you may have no need for sorrow, as others have who are without hope.

14 For if we have faith that Jesus underwent death and came back again, even so those who are sleeping will come again with him by God's power.

15 For this we say to you by the word of the Lord, that we who are still living at the coming of the Lord, will not go before those who are sleeping.

16 Because the Lord himself will come down from heaven with a word of authority, with the voice of the chief angel, with the sound of a horn: and the dead in Christ will come to life first;

17 Then we who are still living will be taken up together with them into the clouds to see the Lord in the air: and so will we be for ever with the Lord.
