As John Broadus once wrote, “Preaching is characteristic of Christianity. No other religion has made the regular and frequent assembling of groups of people, to hear religious instruction and exhortation, an integral part of divine worship.” This is fine, as far as it goes, but I would suggest this quote alone does not go far enough.
Why might we suggest that Christianity is almost preaching-centric? Not because preaching is somehow an end in itself, but rather because Christianity is Theo- and Christo-centric. And what is the critical feature of our God that enables us to come to Him in relationship and worship? It is that He communicates. God speaks. God’s speech is action. He has acted through His Word written and He has acted through His Word incarnate. God’s saving work has been fully accomplished in the person of His Son, His final revelation and message. Consequently we gather together in worship and response to a communicating God. Preaching is not mere instruction and exhortation, on a par with a guided tour of a museum, or a journalist’s report of an incident, or a teacher explaining a theory, or a lecturer sharing their insight, or a coach rallying a sports team, or a motivational speaker stirring salespersons to do better, or an actor reciting a poem, or a judge reviewing the facts of a case, or a politician restating a promise, or a comedian drawing a laugh.
Preaching is unlike any other speech, either instructional or exhortational. When we preach, our goal is to preach the Word, so that the Word of God itself speaks. When the Bible speaks, God speaks. When God speaks, He is at work. Preaching is not just talking about God at work. Biblical preaching is God at work. Perhaps we need to rethink our view of preaching, for too often and too easily, our view of preaching is much too small.
