I think that was Alinsky's coded way of saying that Lucifer is real!
Just as Yeshua doesn't want to be denied, neither does Lucifer. Both require an oath of allegiance.
That's how humans commit themselves and their spirits in just about everything they do.
“Lucifer is real!”
Having seen the evil in men’s eyes and the spirit of the snake crawling through a man, as well as Christ in someone’s eyes, I’d say yes.
Like the movie, “Constantine,” it’s really too bad that some people don’t believe in the Devil because he does believe in them. The 20th century, as in “The Devil’s Advocate,” was almost entirely his. The 21st is falling into the hell hole unless you are protected by The Most High. This is shaping up to be the whirlwind reaped by transgressors.
