In simple language, with touching earnestness, present the truth as it is in Jesus—Ministers need to have a more clear, simple manner in presenting the truth as it is in Jesus.... Those who neglect this part of the work need to be converted themselves before venturing to give a discourse. Those whose hearts are filled with the love of Jesus, with the precious truths of His Word, will be able to draw from the treasure house of God things new and old. They will not find time to relate anecdotes; they will not strain to become orators, soaring so high that they cannot carry the people with them; but in simple language, with touching earnestness, they will present the truth as it is in Jesus.—Selected Messages 1:157. PaM 197.4
Ministers’ words should be select, their speech sound—The deportment of a minister while in the desk should be circumspect, not careless. He should not be negligent in regard to his attitude. He should possess order and refinement in the highest sense. God requires this of those who accept so responsible a work, that of receiving the words from His mouth and speaking them to the people, warning and reproving, correcting and comforting, as the case may require. God's representatives upon earth should be in daily communion with Him. Their words should be select, their speech sound. The haphazard words frequently used by ministers who preach not the gospel in sincerity should be forever discarded.—Testimonies for the Church 2:706. PaM 198.1
