1 Thessalonians 4:13-14

Now we do not want you to be uninformed, believers, about those who are asleep [in death], so that you will not grieve [for them] as the others do who have no hope [beyond this present life]. For if we believe that Jesus died and rose again [as in fact He did], even so God [in this same way—by raising them from the dead] will bring with Him those [believers] who have fallen asleep in Jesus.
