Study not to be a fine preacher. Jericho’s are blown down with rams’ horns. Look simply unto Jesus for preaching food, and what is ranted will be given, and what is given will be blest, whether it be a barley or a wheaten loaf, a crust or a crumb. Your mouth will be a flowing stream or a fountain sealed, according as your heart is. Avoid all controversy in preaching, talking, or writing. Preach down nothing but the devil, and nothing up but Jesus Christ.
John Berridge to Rowland Hill, Sept. 3 1773.
