Another quote from Stott —

“Christian preaching is not the proud ventilation of human opinions: it is the humble exposition of God’s Word. Biblical expositors bring out of Scripture what is there; they refuse to thrust into the text what is not there. They pry open what appears closed, make plain what seems obscure, unravel what is knotted, and unfold what is tightly packed. In expository preaching the biblical text is neither a conventional introduction to a sermon on a largely different topic, nor a convenient peg on which to hang a ragbag of miscellaneous thoughts, but a master which dictates and controls what is said.”

— John Stott, from ‘Paralyzed Speakers and Hearers’, “Christianity Today” (13 March 1981).
