When God saw fit to create a being of wants and of faculties with which to satisfy them, he at the same time decreed that that being should be subject to pain and suffering; for without pain and suffering we can experience no wants, and without wants we cannot understand either the uses or the reasons for any of our faculties. Everything that makes for our greatness has its roots in everything that makes for our frailty.
I discovered later, and I'm still discovering it right up to this moment, that it is only by living completely in this world that one learns to have faith. . . By this-worldliness I mean living unreservedly in life's duties, problems, successes, and failures, experiences and perplexities. In so doing we throw ourselves completely into the arms of God, taking seriously, not our own sufferings but those of God in the world—watching with Christ in Gethsemane. That, I think, is faith. . .
