God is a creative force, And so are we. He told Adam, 'Increase and
multiply.' That's what the first organic cells did, Not merely changed shape but replicated themselves. God is a creative force. He made the whole universe out of Himself through cell division. That's why the devils are so full
of envy-the bad angels, I mean. They are not creative creatures; they have no bodies, no cells, they're spirit. And I suspect it wasn't envy so much as a form of suspicion that God was making a mistake in making another engine of creativity in Adam, so like Himself. I mean the angels probably felt the physical universe was bad enough, with all the replicating cells, but thinking, talking beings who could increase and multiply? They were probably outraged by the whole experiment. That was their sin.
The entire flaw in the Bible is the notion that God is perfect. It represents a failure of imagination on the part of the early scholars. It's responsible for every impossible theological question as to good and evil with which we've been wrestling through the centuries. God is good, however, wondrously good. Yes, God is love. But no creative force is perfect. That's clear.
So this makes a perfectly evil Devil make even less sense than a perfect God. Imagine, the Devil never learning anything during all this time, never changing his mind about being the Devil. It's an insult to our intellect, such an idea. Also, He's not purely unredeemable. He's merely part of God's plan. He's a spirit allowed to tempt and try humans. He disapproves of humans, of the entire experiment. See, that was the nature of the Devil's Fall, as I see it. The Devil didn't think the idea would work. But the key is understanding that God is matter! God is physical, God is the Lord of Cell Division, and the Devil abhors the excess of letting all this cell division run wild.
