In ordinary times we get along surprisingly well, on the whole, without ever discovering what our faith really is. If, now and again, this remote and academic problem is so unmannerly as to thrust its way into our minds, there are plenty of things we can do to drive the intruder away…But to us in wartime, cut off from mental distractions by restrictions and blackouts, and cowering in a cellar with a gas mask under threat of imminent death, comes in the stronger fear and sits down beside us. “What,” he demands rather disagreeably, “do you make of all this? What do you believe? Is your faith a comfort to you under the present circumstances?”
