How do you mean? I've read a fair bit of Christian doctrine and apologia, and I've never seen any substantial volume of material dealing with the actual mechanics of an immortal existence. Usually it's described in terms of an existence of perfect concordance with God's wishes, which implies perfect bliss by some theological sleight of hand but doesn't imply much detail as to what that actually involves, experientially speaking. Certainly nothing concrete on the cultural changes that we'd reasonably expect after defeating the last enemy that shall be destroyed.

The Muslim afterlife's much more detailed, incidentally, but it's just your standard feasts-and-gardens paradise, more or less equivalent to Valhalla but with different cultural foci of enjoyment. I don't find it much more eternity-term compelling than what little we can infer of the Christian version, although I'd probably be more inclined to visit it as a holiday destination.
