what I found quite interesting about what I have read about the Book of Enoch, aside from the fact that he doesn't die, is that the Nephilim/giants are now the demons of today.

Energetically, one thing that occurs to me is: lucifer was created by God as perfect, we are told. Reminds me of HAL in Kubrick's 2001. Something goes wrong.

God saw that and chose to use it to make more perfect spirits for His Kingdom: ones with learned humility.

So now lucifer serves a useful purpose: helping him choose the weeds from the wheat.

The Book of Enoch echos this in the sense that rather than destroy the mutated spirit energy of the Giants, he chose to keep them in the other dimension w lucifer and minions, again, to separate those who would follow Him with learned humility and wisdom, from those who choose a more self-oriented path.
