1 Thessalonians 4:13
But we do not want you to be uninformed, brothers, about those who are asleep, that you may not grieve as others do who have no hope — 'asleep' (koimaomai) is the metaphor for death; the Thessalonians wrongly fear their deceased brothers are excluded from the parousia. Paul corrects the ignorance (agnoeo) with eschatological hope (elpis). Grief is not forbidden but is transformed by hope.
