Doubt and Faith

Tony Award and Pulitzer Prize-winning playwright of "Doubt," John Patrick Shanley, wrote an OP-ED piece, "The Benefit of Doubt," in today's Boston Globe I found interesting. He concludes his article saying,

Doubt is not paralysis. Certainty is. Doubt keeps the doors and windows open. Belief is one room with no way out. Do not let others impose a polarity of response on you. You need not live a reactive life. Don't look to have life explained to you, presented to you. Live the life that emanates from your interior greatness. Be an overwhelming bounty of impressions, ideas, conflicting theories, and let the propellant behind all this be generosity. A giving...I invite you to passionately doubt everything you believe.

Are doubt and belief opposites? Is belief one room with no way out? Is there a place in discipleship for a healthy sense of doubt? Is doubt one room with no way out? What do you do with doubt in your own life?
