In other words, the preacher must make sure his hearers are engaged with him, and he with them, in what he is saying â€“ engaged with the mind, in the first place; but not merely with the mind. Surely this is obvious, isnâ€™t it? But how few really engage with their hearers? I have already spoken of a slumbering congregation under a slumbering preacher. We shall never engage with people if we or they are semi- comatose. Preachers must know â€“ they must feel â€“ how their hearers are reacting, and respond accordingly.
