is almost always my first thought when someone mentions the(a) choosen[sic].
for me the biblical prophecy is partly a specific reference to the group of ancients that brought the Christ resurrection working online. So after the societal change with the death of Caesarion, during their slumber of the last age, their souls wouldn't disintegrate during reincarnation due to lack of divine awareness while incarnate. Astronomical precession predictably breaks the mechanics of it as the ancient astral working falls out of alignment.
During its operation everyone could take advantage of it by only having to accept Christ, a path to sleepwalk. But only the ancients and those that reached initiation in the meantime will survive resurrection without it.
It's operation has led to many souls retaining coherence and reincarnating that wouldn't have otherwise. Those that cannot adapt to taking responsibility for their own resurrections by way of aligning with heavenly virtue through earthly deed will not survive reincarnation as the Angels clean house(s). This cleansing is part of the reason for the desperation of so many currently incarnate souls trying to get back to that fallen age to continue exploiting without the consequences of vice.
