Omnipotence Dean Zimmerman, Negative Nelly, and the Divine Delegates

Should an omnipotent being be able to limit its own power? Along with Swinburne, Dean Zimmerman answers in the affirmative. My intuitions push in the opposite direction. The ability to limit one's own power constitutes a vulnerability. In this paper, I argue that a great deal hangs on this issue. If God cannot revoke His own omnipotence, then only a necessarily existent being can ever create anything truly ex nihilo. Moreover, if God cannot revoke His own omnipotence, then it turns out that theism entails idealism. No wonder that Zimmerman resists.
