That's an earth-shattering verse, Albion, because it goes against all the "lovey-dovey God" talk of the last 3 or 4 generations. But what we read is that God MAKES THEM DELUDED. Why? In order to condemn them!
I grew up being taught that God doesn't condemn anyone, but people's stubornness to believe SELF-condemns them. That's not what I read.
