It is not necessary for a preacher to express all his thoughts in one sermon. A preacher should have three principles: first, to make a good beginning, and not spend time with many words before coming to the point; secondly, to say that which belongs to the subject in chief, and avoid strange and foreign thoughts; thirdly, to stop at the proper time.
Martin LutherWe come to the New Testament, where again a host of imperative verbs is mustered in support of that miserable bondage of free-choice, and the aid of carnal Reason with her inferences and similes is called in, just as in a picture or a dream you might see the King of the flies with his lances of straw and shields of hay arrayed against a real and regular army of seasoned human troops. That is how the human dreams of Diatribe go to war with the battalions of divine words.
