1 Thessalonians 4:11-14

and that you make it your ambition to lead a quiet life, and to do your own business, and to work with your own hands, even as we instructed you, that you may walk properly towards those who are outside, and may have need of nothing. But we don’t want you to be ignorant, brothers, concerning those who have fallen asleep, so that you don’t grieve like the rest, who have no hope. For if we believe that Jesus died and rose again, even so God will bring with him those who have fallen asleep in Jesus.
