1 Thessalonians 4:13-15

Beloved brothers and sisters, we want you to be quite certain about the truth concerning those who have passed away, so that you won’t be overwhelmed with grief like many others who have no hope. For if we believe that Jesus died and rose again, we also believe that God will bring with Jesus those who died while believing in him. This is the word of the Lord: we who are alive in him and remain until the Lord appears will by no means have an advantage over those who have already died, for both will rise together.
