If the Christian faith is true, it is true even if no one believes it, and if it is not true, it is false even if everyone believes it. The truth of the faith does not stand and fall with our defense of it.

The Christian faith is not true because it works. It works because it is true.

What is the difference between God disguising himself and deceiving us? That is where the principle of suspended judgment operates. Face to face with mystery, and especially the mystery of evil, the faith that understands why it has come to trust must trust where it has not come to understand. Faith does not know why in terms of the immediate, but it knows why it trusts God who knows why in terms of the ultimate.

If ours is an examined faith, we should be unafraid to doubt. If doubt is eventually justified, we were believing what clearly was not worth believing. But if doubt is answered, our faith has grown stronger. It knows God more certainly and it can enjoy God more deeply.

Not only do Christians believe, they are those who "think in believing and believe in thinking," as Augustine expressed it. The world of Christian faith is not a fairy-tale, make-believe world, question-free and problem-proof, but a world where doubt is never far from faith's shoulder.

If we truly know why we trust God—and that crucial if must be answered with full intellectual and spiritual assurance—if we truly know why we trust God, then God is greater than all, and God may be trusted in all situations, despite everyone and everything.

Whether or not the Christian faith is true is now irrelevant. All that matters is that to more and more people in the modern world it no longer seems true.

To come to faith on the basis of experience alone is unwise, though not so foolish as to reject faith altogether because of lack of experience ... the quality of a Christian's experience depends on the quality of his faith, just as the quality of his faith depends in turn on the quality of his understanding of God's truth.

Man can believe the impossible, but man can never believe the improbable.

Naturally, we are inclined to be so mathematical and calculating that we look upon uncertainty as a bad thing...Certainty is the mark of the common-sense life. To be certain of God means that we are uncertain in all our ways, we do not know what a day may bring forth. This is generally said with a sigh of sadness; it should rather be an expression of breathless expectation.

Faith is not intelligent understanding, faith is deliberate commitment to a Person where I see no way.

The test of mountain-top experiences, of mysticism, of visions of God and of solitariness is when you are "in the soup" of actual circumstances.
