One of the dirtiest little secrets about preaching is that many preachers are using what we used to call in radio “a service.” There are, or at least there used to be, businesses that sell jokes and one liners and gags and the like to “radio personalities.” We referred to these business as “a service” as in, “Wow, his show is terrible.” “Well, I’m not surprised, he uses a service.” If a “personality” needs a service he isn’t really much of a personality is he?
