I’ve often heard it said that hell is, in essence, eternal separation from God and everything good that we can experience, which is all bound up in him. The author of this blog post (http://against-heresies.blogspot.com/2007/12/separation-from-gods-presence.html) takes issue with that view of hell, concluding that it’s only half right:
“Hell is not spatial separation from God, it cannot be because God is omnipresent. No, Hell is separation from the comfortable presence of God. It is the unshielded experience of the presence of God in his holiness and just wrath, and the absence of his mercy and grace.”
In other words, hell is both the eternal separation from everything good and comforting about God and the eternal presence with God in the experience of the full force of his holy wrath against sin — yikes.
