In the first part, I point out that before Jesus’ mission was finished, souls of the dead slept in the Limbo. Upon His ascension, they were given new bodies, and anyone who died or will die thereafter is also instantly embodied upon death.
An illustration of one part of this understanding is found in 1 Sam 28, an episode with the witch of Endor who brought up the spirit of prophet Samuel for king Saul. She summoned a “ghostly figure” who looked like an “old man wearing a robe.”
The old man was predictably cantankerous. But apparently for a reason; he says: “Why have you disturbed me by bringing me up?” Then Samuel predicts a vast amount of gloom and doom for Saul.
I admit, there isn’t much to go on with this exchange. From what was Samuel disturbed? From contemplating God while fully awake or from sleeping?
Well, a man who is perfectly happy would probably have enough self-esteem not to be as cruel to Saul as Samuel was. I say, therefore, that Samuel — or rather his ghost, a being with will and intellect but no power — was sleeping, and he did not appreciate being awakened, when it was not yet time for ghosts to come unto Jesus.
