The passing of time is of no moment to sleeping mortals; they are wholly unconscious and oblivious to the length of their rest. On reassembly of personality at the "End of an Age", those who have slept five thousand years will react no differently than those who have rested five days. Aside from this time delay these survivors pass on through the ascension regime identically with those who avoid the longer or shorter sleep of death.
“But what is the significance of this teaching having to do with the coming of the Sons of God? Do you not perceive that, when each of you is called to lay down his life struggle and pass through the portal of death, you stand in the immediate presence of judgment, and that you are face to face with the facts of a new dispensation of service in the eternal plan of the infinite Father? What the whole world must face as a literal fact at the end of an age, you, as individuals, must each most certainly face as a personal experience when you reach the end of your natural life and thereby pass on to be confronted with the conditions and demands inherent in the next revelation of the eternal progression of the Father’s kingdom.” ~ Jesus
