Before Adam was cast out of the Garden of Eden (into the world in which death would enter, and Adam would be obligated to succumb to that death), there was an anointing oil prepared in Eden itself that was designed to be used in order to help the Descendant of Adam who would come to crush the head of the serpent—that, once He was anointed, would equip Him to come back from the grave and be resurrected. And that was entrusted into Adam’s care before he was cast out of the Garden, as something to be preserved and handed down until the time that the Messiah comes. And as circumstances would have it,
that got passed from those that had the responsibility, down through the generations— until finally, Melchizedek turned it over to father Abraham, who, in turn, handed it down through his lineage. And subsequently, there was a line—entrusted not only with possession of the anointing oil that came from Eden but also knowledge about the signs that would be given when the moment came for the oil to be delivered.
And so it was that the sign was given. They recognized and interpreted it correctly. They went to the place where it had been stored by their ancestors. They retrieved it, and then they traveled to find Him who was born the King of the Jews. And upon finding the family (with a sign that signified—from above, according to their understanding and interpretation of the signs—that this was the child, this was the family), they delivered the gifts, which were, in turn, used.
But the oil for anointing was kept. And that oil was handed down, until finally, the moment came when the Savior intended to go up and to provoke His crucifixion. And preliminary to that moment, Mary (the mother) instructed Mary (the consort of Christ) in the manner by which this was to be done. And so, He was anointed—in preparation for His death and His burial and His rising again—with what had been set out and kept (originating in Eden), to be used in order to complete the process of qualifying Him to return again, to have strength in the loins and in the sinews, and the power to rise again from the dead and to lay hold upon all of the faculties of the immortal, physical body.
And so, He was anointed—at the end—with the oil that had been entrusted, originally, to Adam and handed down with an obscure and small body of believers (who were dying out and who were older—and the last of their tradition, it seemed). But the Messiah came, and they discharged the obligation; and the blessing was able to be given, and the Savior was able to rise from the dead. And so, He opened the way, then, for the return from the grave of everyone who has faith on His name and accepts (on condition of repentance) the terms to have His atonement applied to us.
