People are desperate for the word, for God's Word, just as we are.
Go ahead, admit it: you almost never ask this question. Except, perhaps, on the occasional Saturday night, when it’s late and you’re tired, frustrated, looking at a blank screen wondering when, maybe if, the Holy Spirit is ever going to show up and nudge you toward a sermon.
But even though the question of why we preach is rare–and, take my word for it, it is rare, hardly ever coming up even in a homiletics text book–it’s still an important one. Because the thing is, your basic sense of why you preach greatly, if often unconsciously, shapes each and every sermon you deliver. If, for instance, you think we preach in order to teach the faith, your sermons are going to be highly didactic. Whether you choose to print outlines in your bulletin, tell stories, or employ PowerPoint, your sermons will still be largely educational in nature. Similarly, if you think the primary purpose of preaching is moral exhortation, then no matter what form your sermon may take or what various means of communication you may employ, your sermons will consistently take aim at strengthening the moral life of your hearers.
Get the point? The “why” of preaching–that is, what we think preaching is primarily about–dramatically shapes both the “what” and the “how” of our preaching as well.
So, why preach? Truth is, of course, that there is no single answer. It depends on so many things, including our own theology, our life experience, and our sense of the nature of Christian worship; just to name a few. But while I can’t answer this question for you, I can at least share my own sense of the purpose and import of preaching. To get at this, though, I need to go back just a little further, beginning first not with why I preach, but why I listen; that is, why I want and need to hear a good sermon in the first place.
Okay, with this in mind, it’s time for me to come clean: for me, you see, listening to a good sermon is a matter of desperation. That’s right, desperation. Because, if I’m going to be honest, I have to confess that I sometimes find it hard to believe. In the face of the evening news, with all of its stories of human misery and suffering, the good news of the gospel can seem a little hard to believe. I mean, think about it: week in and week out we preachers proclaim not just that is there a God who created the vast cosmos and still sustains them, but that this God not only knows that we exist but actually cares, deeply and passionately about our ups and downs, our ins and out, our successes and failures, our aspirations and disappointments. See what I mean? This is a message that is just this close to being too good to be true.
