To preach the Gospel requires that the preacher should believe that he is sent to those whom he is addressing at the moment, because God has among them those whom He is at the moment calling; it requires that the speaker should expect a response.

“I don't want people poking around in my private stuff. They've no business in it. My work is what I give to people, that's my job, and that's where it stops.”
