Many of those who come to a belief in the God of classical theism do so solely as a result of having had an experience which they believe it is reasonable for them to interpret as a revelation of His existence directly and graciously given to them by God Himself. I shall argue that – at least in the first instance – such people should probably not think of themselves as knowing that there is a God if they are also traditional libertarians and believe in Robert Nozick's theory of knowledge.
