“Skeptics believe that any exclusive claims to a superior knowledge of spiritual reality cannot be true. But this objection is itself a religious belief. It assumes God is unknowable, or that God is loving but not wrathful, or that God is an impersonal force rather than a person who speaks in Scripture. All of these are unprovable faith assumptions.” Keller, Timothy. The Reason for God: Belief in an Age of Skepticism (p. 12). Penguin Publishing Group. Kindle Edition.
Even atheists assume based essentially on faith that there is no higher power.
