I'm referring to all of the verses (mostly in the OT) that talk about sleeping. Daniel is told he will sleep, but then...that's before Christs resurrection and before the verse in one of the gospels that says: and they saw many of their dead walking around.
1. The OT did not give us the full picture of the afterlife, for the simple reason that that would have to be revealed after the death, burial, and resurrection of Christ. However the cults love to focus on the OT and promote their Soul-Sleep doctrine, because they really do not understand what Christ accomplished in His death burial and resurrection.
2. The word "sleep" was applied to BOTH the dead body in the grave as well as the soul and spirit silent in Sheol (which is Hades).
3. Until the resurrection of Christ, all the righteous dead were silent in the place called "Abraham's bosom" (in Sheol), so metaphoricially they were asleep. But we know from the narrative of the Rich Man and Lazarus, that they were not really asleep either in Sheol or in their graves.
4. There are times when the KJV translators translated the Hebrew word "sheol" as "grave", thus adding to the confusion. There were other times when they translated Sheol/Hades as "hell" further compounding the confusion.
5. At the time of the crucifixion and resurrection, some of the OT saints were indeed resurrected. However, the majority of them were taken to Heaven (more precisely the New Jerusalem) when Christ ascended and "took captivity captive". Meaning that they had been held captive in Sheol until the resurrection of Christ, at which time they were perfected and became "the spirits of just men made perfect". See Hebrews 12:22-24.
6. To confirm that after the resurrection of Christ all believers go directly to Heaven, study the martyrdom of Stephen, where his body went, and where his soul and spirit went.
