" I belong to the Reformed tradition, and may have had perhaps a little to do in Britain with the restoration of this emphasis during the last forty years or so. I am disturbed therefore when I am often told by members of churches that many of the younger Reformed men are very good men, who have no doubt read a great deal, and are very learned men, but that they are very dull and boring preachers; and I am told this by people who themselves hold the Reformed position. This is to me a very serious matter; there is something radically wrong with dull and boring preachers. How can a man be dull when he is handling such themes? I would say that a ‘dull preacher’ is a contradiction in terms; if he is dull he is not a preacher. He may stand in a pulpit and talk, but he is certainly not a preacher. With the grand theme and message of the Bible dullness is impossible. This is the most interesting, the most thrilling, the most absorbing subject in the universe; and the idea that this can be presented in a dull manner makes me seriously doubt whether the men who are guilty of this dullness have ever really understood the doctrine they claim to believe, and which they advocate. We often betray ourselves by our manner. "
