Preacher: butcher or cook?

Jay Adams puts it well, I think:-
Whitehead said, “A merely well-informed man is the most useless bore on God’s earth.” All of us know how desperately dull preachers can become at imes when they try to teach. But the transmission of information certainly doesn’t need to be dull. Rather, it can be exciting and interesting. Preachers must not become Bible butchers, chopping out great chunks of scriptural meat and throwing them raw and bloody to their congregations as if they were feeding tigers. There is nothing wrong with the meat. There is nothing wrong with the butchering process. But preachers must also learn to become cooks as well as butchers. They must learn to serve the meat well cooked, warm, well-seasoned, garnished, with an appetizer and dessert, by candlelight. Most congregations choke and gag on a slab of raw doctrine, even if it is a prime cut. The preacher as butcher does research; the preacher as cook and host presents his materials in palatable, digestible, and inviting form.
