I have sympathy for the view that sin is the absence of God, but I'm not sure I'm following you here. How do you explain all the specific physical actions God has taken in the Bible that we associate with His wrath, such as the flood, etc.?
Slightly longer answer: Okay, my thought is incomplete. But the Flood (or Osama, or whatever) isn't what I'm afraid of. Another 30 some years and I'm outta here anyway. What I'm afraid of is what happens THEN. And that's what I'm talking about in my the wrath on the sin is included in the sin.
If my make a cartoon of Hugh Hefner, just for argument's sake: he could die of syphilis or AIDS or being shot by a jealous lover or something. But when he dies, unless God works a miracle in him, what will be there is a person who thinks everything on earth or at least everything in skirts is for his pleasure - for his service only in a barnyard sense, not in the sense which the Lord had in mind, and who may have lost the capacity to love. That's the eternal fire, I think.
Sketchy answer given in haste.
