I heard pastor/theologian John Piper recently say something like (this is my paraphrase): "The only way I can possibly be totally satisfied for an eternity, is in the presence of the infinitely good God." One of the biggest influences on my imagination in this regard has been NT Wright's focus on 'the new heavens and the new earth' - the redemption and bringing together of both - I haven't read Alcorn on this but I imagine there's a shared focus on the Bodily reality of things.
