Paula Kirby argues that heaven, as it is often imagined, would be horrid:
In the state of permanent, perfect bliss that is the very definition of heaven, ‘making a difference’ is ruled out. If the difference made an improvement, the previous state could not have been perfect. If it made things worse, the result would not be perfect. In heaven, neither is possible. Even being reunited with loved ones could not add one jot to their bliss or yours, for heaven would be, by definition, a state that could not be improved on. Just consider for a moment the hellish pointlessness of heaven. At least in our real existence our actions have an effect, for better or worse, and it is therefore worth trying to get them right. In an eternal life where we can have no effect whatsoever, we might as well be dead.
