The desire for proof is not the same as the desire for truth. The desire for proof is actually the opposite of truth.
One’s desire for proof stems from knowing it pleases his intellect without the trouble of needing to believe. But belief is knowing the pleasure of God without needing intellectual proof. Strange as it seems, proof is actually cheating. In demanding truth prove itself true, one willfully cheats on the troublesome test of faith. Intellectually, one would happily prefer knowing the ruby slippers on his feet take him home right at the start rather than go through the trouble of the Wizard of Oz. But that’s a cheat because intellectually knowing how to go home isn’t the same as going home. There is only one way to go home. And the only way to prove it is to believe.
