Hello Dancing Red Feather,
This question seems to have been hanging around for a bit, so here goes:
Sleep = death that's all. Here in Thessalonians Paul states it like this:
1 Thess 4:13 (KJV) But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
All people sorrow over departed loved ones and yet Paul says here we are not to mourn in the same way over those who are Born Again and yet die, for theirs is the resurrection.
