“And yet when I wish to explore how faith works, I usually sneak in by the back door of doubt, for I best learn about my own need for faith during its absence. God's invisibility guarantees I will experience times of doubt. Everyone dangles on a pendulum that swings from belief to unbelief, back to belief, and ends - where?”

“Faith isn't absence of doubt. It's belief without proof, not without question.”

“If faith never encounters doubt, if truth never struggles with error, if good never battles evil, how can faith know its own power? In my own pilgrimage, if I had to choose between a faith that has stared doubt in the eye and made it blink, or a naive faith that has never known the firing line of doubt, I will choose the former every time.”

“The road to hell isn't paved with gold, it's paved with faith. Faith in a dollar that's backed by a belief that people have faith in other people's belief in it.”

“How could anyone understand the pain of a faith betrayed? He had believed. And yet, when he had needed hope the most, he had found only emptiness... Belief isn’t simply a thing for fair times and bright days, I think. What is belief—what is faith—if you don’t continue in it after failure. . . .”

“It's strange how the human mind swings back and forth, from one extreme to another. Does truth lie at some point of the pendulum's swing, at a point where it never rests, not in the dull perpendicular mean where it dangles in the end like a windless flag, but at an angle, nearer one extreme than another? If only a miracle could stop the pendulum at an angle of sixty degrees, one would believe the truth was there.”
