OK, so? They're absolutely blocking out God's love, and that's what produces this effect on them ... despite the fact that physical metaphors fall short of describing it.
[ . . . ]
Another metaphor that I use is that some find bliss in listening to classical music. Others, however, if they're asked to listen to classical music, say, in music class in school, find it abhorrent, are crawling out of their skin with boredom and disgust, can't wait to get out of there, etc. It's the same music, but it causes one happiness and another unhappiness and pain. It's the same music, but different listeners.
That's precisely my point.
People that don't like classical music are not blocking it out when they hear it, truly they hear it.
Likewise, if souls don't want God's love, and the fire is supposed to be God's love, then they're not blocking it out, they're experiencing it in anguish.
