Do not give the people more than they can remember—Let the message for this time be presented, not in long, labored discourses, but in short talks, right to the point. Lengthy sermons tax the strength of the speaker and the patience of his hearers. If the speaker is one who feels the importance of his message, he will need to be especially careful lest he overtax his physical powers, and give the people more than they can remember.—Gospel Workers, 167, 168. PaM 199.3
When the discourse is too long, the last part detracts from that which preceded it—Speak short. Your discourses are generally double the length they should be. It is possible to handle a good thing in such a manner that it loses its flavor. When a discourse is too long, the last part of the preaching detracts from the force and interest of that which has preceded it. Do not wander, but come right to the point.—Testimonies to Ministers and Gospel Workers, 311. PaM 199.4
That which is spoken in the first hour is of far more value if the sermon closes then—Those who shall be mouthpieces for God should know that their lips have been touched with a live coal from off the altar, and present the truth in the demonstration of the Spirit. But lengthy discourses are a taxation to the speaker and a taxation to the hearers who have to sit so long. One half the matter presented would be of more benefit to the hearer than the large mass poured forth by the speaker. That which is spoken in the first hour is of far more value if the sermon closes then than the words that are spoken in an added half hour. There is a burying up of the matter that has been presented.—Testimonies to Ministers and Gospel Workers, 256. PaM 199.5
