1 Thessalonians 4:13-15

13Brothers 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. 14For 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. 15According to the Lord’s word, we tell you that we who are still alive, who are left until the coming of the Lord, will certainly not precede those who have fallen asleep.
