Tim, you ask a very God-honoring question when it comes to homiletical introduction. Creating or surfacing need is certainly part of what an introduction must do. In fact, as Peter states in his 5/11/2007 entry, an introduction must do four things. It must get attention, create rapport, establish authority and create or surface need. Yet, for these four components to be God-honoring and not man-honoring (which I believe gets at the heart of your question), David Buttrick, in Homiletic Moves and Structures makes a very important point. He states that an introduction must do two things. First, it must give focus to consciousness. Second, it must provide some sort of hermeneutical orientation.
Buttrick is not contradicting the points that Peter makes. In fact, within his chapter on introductions, he makes some of the very same points. Rather, Buttrick establishes an overarching principle that is to contour and influence the direction of the points that Peter makes. In other words, while doing all that Peter has encouraged us to do in an introduction, focus and orientation to the text must occur. This can be difficult. It is much easier get attention, create rapport, establish authority and surface need autonomous from the text that is supposed to be introduced. This happens all the time in preaching and it is a colossal error.
It is all too easy to imagine isn’t it? The preacher stands, opens his Bible, takes out his notes and begins. He starts by catching attention and building rapport through funny or shocking stories. The audience laughs or gasps – sometimes both simultaneously (it is a weird sort of convulsion). The room emits an ethos of warmth and openness and then, the preacher begins to preach. The problem is that the first five minutes had nothing to do with the sermon. The congregation is now enthralled with the preacher not the passage. So, after “warming-up” and “catching the attention” of the congregation, the preacher has to spend another five minutes on a second introduction – this time, focusing on the Word of God. This is a terrible waste of time.
To be clear, the four points that Peter makes need to happen in an introduction. However, they must happen in a way that focuses consciousness and provides some sort of hermeneutical orientation to the passage that is going to be preached. This will take more preparation time, and a lot more effort, but it is worth it. We must capture the attention of our audience while concurrently directing them toward God and His Word. Any other result is not an introduction.
