And yet, obvious as these principles are, the art of the sermon maker needs learning, and even the study of methods of delivery is of immense importance to success. We have spoken of "the born preacher"; even _he_ must cultivate his gifts in order to realise his highest possibilities. We speak sometimes of "diamonds in the rough"; the value of these precious stones increases as the art of the lapidary is carefully exercised upon them. If it be only to prevent the formation of false methods and bad habits of thought and utterance, a preacher should give attention to the study of Homiletics. He may, as the end of all his studies, feel led deliberately to reject much of what he has been taught in favour of original methods of his own. As the years go on he may forget many of the rules laboriously learned. Neither of these circumstances should be held to prove that time spent in the sermonising class has been wasted. It is a fact that most of us have forgotten the greater part of what we learned at school. The dates which made up so large a part of our historical lessons, the rules we slavishly committed as we struggled to master the difficulties of syntax and prosody, our latinity, our grounding in the tongue of ancient Greece so hardly won--who amongst us, having grey hairs in abundance, could face to-day the examination room where once we triumphed in these things? Yet in a sense they are all still with us. We reproduce them in effectiveness in the daily battle; in the thousand and one duties forming the work of life. It may be much the same in the case of homiletics. We may reject; we may forget; but we cannot altogether fail to profit richly in many ways from studies the object of which is to make the student more skilful in the use of the powers bestowed upon him. Had these pages been written for young men only, they would have contained more than one chapter devoted to an effort to enforce the absolute necessity of bending the mind, and with the mind the heart, to the earnest pursuit of all that can be learned about the actual building-up of discourses from the foundation of exegesis to the topstone of application. We do not refrain from emphasising this necessity because of any thought that even the elder brethren will find such studies without profit. To read once more some of the homiletic manuals of our far-off days, would not be for many of us a foolish method of spending a quiet hour "between the mount and multitude!"
