1 Thessalonians 4:11-14

and to make it your ambition to lead a quiet life: You should mind your own business and work with your hands, just as we told you, so that your daily life may win the respect of outsiders and so that you will not be dependent on anybody. Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest of mankind, who have no hope. For we believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him.
