Divine Hiddenness and Divine Humility

If God exists, and if our ultimate well-being depends on having a positive relationship with Him (which requires as a first step that we believe He exists), why doesn't He make sure that we all believe in Him? Why doesn't He make His existence obvious? This traditional theological question is today much-used as an argument for atheism. In this paper I argue that the answer may have something to do with God's character, specifically God's humility.
