SourceThe importance of preaching is God's chosen instrument for doing good to souls. By it sinners are converted, inquirers led on, and saints built up. A preaching ministry is absolutely essential to the health and prosperity of a visible church. The pulpit is the place where the chief victories of the Gospel have always been won, and no Church has ever done much for the advancement of true religion in which the pulpit has been neglected. Would we know whether a minister is a truly apostolical man? If he is, he will give the best of his attention to his sermons. He will labor and pray to make his preaching effective, and he will tell his congregation that he looks to preaching for the chief results on souls.
