At my church, my pastor is quite adamant about a particular type of preaching. I'm well aware of alternative methods of preaching. It seems to me these methods are quite important; to the lay person as well as the pastor.
Can I ask a question about the biblical basis for a method of preaching?
E.g, "What is the biblical basis for the topical sermon series?" or "What is the biblical basis for a lectio continua systematic expository sermon method?"
Obviously, as with all questions, I'd be asking an objective question (what is the biblical basis) not a subjective one (which is better).
