" Like most ministers, Peter was not the best judge of his own sermons. Almost invariably when he thought he had written one of his best, the rest of us did not rate it so highly. And, when on Saturday night he was bemoaning a "terrible sermon," he could be pretty sure his congregation would think it terrific. How other people rated his sermons was a constant source of astonishment to him. "That's what keeps me humble," he often said. "
