A Catholic friend of mine once said "If Calvin's God exists, I would insist on being damned. But it would do me no good."
This of course presupposes that if God determines your fate before the foundation of the world, your actions then do not determine it, since if your actions had been different in 2009, it would have changed something that occurred before the foundation of the world, which would be changing the past and therefore impossible.
Let us set that aside for a moment, however. And let's not make this exclusively about Calvinism. Someone could say "If Wesley's God exists, I would insist on being damned" or even "If Talbott's God exist, I would insist on being damned" since you could argue that even in Talbott's universalist world, there is gratuitous evil that God should not have permitted. And let us assume further that refusing to worship an all-powerful being is the supreme sin against prudence.
The question I have, for any theology, has to do whether we have a moral obligation, as opposed to a merely prudential obligation, to worship an infinite being. If so, where does that moral obligation come from?
