I also know that it just happens to be true

"Sometimes when we lose ourselves in fear and despair, in routine and constancy, in hopelessness and tragedy, we can thank God for Bavarian sugar cookies. And, fortunately, when there aren't any cookies we can still find reassurance in a familiar hand on our skin or a kind and loving gesture or a subtle encouragement or a loving embrace or an offer of a comfort. Not to mention hospital gurneys, nose plugs, an uneaten Danish, and soft spoken secrets, and Fender Stratocasters, and maybe the occasional piece of fiction.

"And we must remember that all these things, the nuances, the anomalies, the subtleties, which we assume only accessorize our days, are, in fact, here for a much larger, nobler cause. They are here to save our lives. I know the idea seems strange but I also know that it just happens to be true."

Name that movie, folks, and the corresponding Gospel principle in these words.
