I didnt read the full post, but you are right, there is no soul sleep .. Sleep is just a euphemism in the bible for death. Its used often in the OT, for the good and wicked.
But, it can also be a figure of speech for spiritual deception. The Greek gives good clue in the NT for which is which ; for the most part .
If you use a strong concordance , there were two greek words often used ..One means to compose oneself for sleep, or rest, voluntarily .
The other is involuntary sleep; meaning death .
In Daniel, that verse you cited, is spiritual deception or in a poor spiritually mortal state ; is what is indicated .
... Its like passage is found in 1 Corinthians 15: 52- 53 For this corruptible must put on incorruption, and this mortal must put on immortality.
The subject matter is the same as
Dan 12:2 And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
When you sleep in the dust of the earth, you're said to be spiritually dead. Since the passage is talking about the return of Christ, you have to be cognoscente of what caused the spiritually dead state ( meaning to have a mortal soul in the context ) just prior, in the 6th Trump of Satans tribulation .. Apostasy ..
1 Corinthians 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Again ; ( spiritually dead , is taught with the figurative language ; for those that sleep in the dust of the earth ) .
No one sleeps literally in the earth at death.. Christ showed us the Truth of life and death when He resurrected immediately after death. Then three days later His physical body transfiguring along with Him.
Acts 7:60 This is the Greek koimaomai = to fall asleep (unintentionally). Hence is used of death, as it is involuntary while katheudo is voluntary. Except maybe 4 places in scripture.
1 Co 11:30 Even though i think this uses the Greek for koimaomai sleep, the passage is talking in a spiritual sense.
1 Co 15:51 Again koimaomai unintentionall and is speaking of literal death. Paul simply saying, if you're living at the return of the real Christ, then you'll not die a normal death, you'll be changed . Their physical resurrection is initiated instantly at that time . This is even mentioned again in 1Th 4:17 ( we which are alive and remain unto the return of Christ ) ..
1Th 4:13 Again literal death koimaomai .
Have a merry Christmas ..
