When the one thing you want is a complete shadowless grasp of every aspect of even just one simple thing in this life, when you have dug down to the deepest stratum of your understanding and are confronted by mystery—deep impenetrable mystery—and come to realize that you do not understand, cynicism will be calling to you like a siren. If you accept the call, that cynicism will treat the darkness (which is the mystery at the core of your existence) as if comically inconsequential. It will detach itself from all meaningful possibilities, and perpetuate its fundamental drive to preserve itself and itself only.
Real faith, on the other hand, acknowledges this mystery and allows doubt to do its work—to scrutinize, interrogate, and rail against the parameters of understanding. It will employ doubt to bring future possibilities to the foreground, and use wisdom to press toward those possibilities and displace the undesirable ones to the background. In other words, “faith digs down to the deepest stratum and finds trust. Practical trust.” [Nicholas Wolterstorff, Thomas Reid and the Story of Epistemology] Hope is that trust directed toward the future.
