“Unbelief cannot sustain itself; it is unable to make sense of the facts, many of which are the most obvious facts of the world; it assumes, rather than shows, that there is no God, that the world is not created by him, that his character is not obvious in creation, and so on. Then it proceeds to argue its case not by attempting to support those assumptions, but simply by assuming them and then arguing as if the assumptions themselves are, or must be, universal if one is to be “rational.”
