Preaching with One Idea

Rule 1: Tell them one thing, and one thing only
Though in the business of public speaking, Nick Morgan admits that the oral genre is highly inefficient:
We audience members simply don't remember much of what we hear. We're easily sidetracked, confused, and tricked. We get distracted by everything from the color of the presenter's tie to the person sitting in the next row to our own internal monologues.


So you've got to keep it simple. Many studies show that we only remember a small percentage of what we hear — somewhere between 10 – 30 percent.
Unfortunately, we can only hold 4 or 5 ideas in our heads at one time, so as soon as you give me a list of more than 5 items, I'm going to start forgetting as much as I hear.

Morgan's solution?

Against this dismal human truth there is only one defense: focus your presentation on a single idea. Be ruthless. Write that one idea down in one declarative sentence and paste it up on your computer. Then eliminate everything, no matter how beautiful a slide it's on, that doesn't support that idea.

John Stott argues for something similar to this in Between Two Worlds. He says the preacher should isolate the dominant thought of a passage and organize his whole sermon to support that one thought. Jay Adams has the same idea in Preaching with a purpose.

Challies on Idol of Communication

Idols are typically good things that seek to become ultimate things. Communication is just the kind of good thing, the kind of very good thing, that can so easily become an ultimate thing. How would we know that there is an idol in our lives? It may be the kind of thing we look at right before we go to sleep and the first thing we give attention to when we wake up. It may be the kind of thing that keeps us awake even in the middle of the night. A 2010 study by Oxygen Media and Lightspeed Research sampled the the habits of 1,605 young adults. The researchers found that one third of women between the ages of 18 and 34 check Facebook when they first wake up, before they even head to the bathroom; 21% check it in the middle of the night; 39% of them declare that they are addicted to Facebook.

We might also know we serve an idol when it is something we carry around with us at all times. A Pew Research study found, not surprisingly, that cell phone use is nearly ubiquitous today. Three-quarters of teens and 93% of adults between ages 18 and 29 now have a cell phone. Cell phone use has grown substantially among pre-teens so that 58% of 12-year-olds now own one. Lisa Merlo is a University of Florida psychiatrist who studies digital addictions—addictions to the Internet and other technologies. She finds that for a growing number of people the need to be in constant communication is so powerful that they cannot even turn off their cell phones in order to sit through a two-hour movie. Their obsession with their phones resembles any other form of addiction. “As with traditional addictions, excessive cell phone use is associated with certain hallmark patterns of behavior, including using something to feel good, building up a tolerance and needing more of it over time to get the same feeling, and going through withdrawal if deprived of it.” Meanwhile a recent Japanese study found that children with cell phones tend not to make friendships with children who do not have them. And all of this is really just the tip of the iceberg. Communication is just what we do today.

By all appearances we have made communication into a kind of cultural idol. In most cases it is not Facebook or the cell phone that is the idol. Instead, they serve as enablers, as enhancers, of the greater idol of communication. Christians have proven to be far from immune to this idol, from following along as the culture around us becomes obsessed with communication and dedicates vast amounts of time and resources to it. Christians will do well to remember that in God’s economy communication is but a means to the far greater, far more noble end of enjoying God so we can bring glory to him. Communication can detract from this purpose just as easily as it can serve this purpose.

When words serve God, they draw hearts to what is of greatest importance. Such words are full of meaning, full of life. When words serve an idol, they distract, they damage, they focus on quantity over quality. Thus words call us not just to use them sinlessly, but to use them to share what is substantial, to say what is best, to encourage, to bless. In an age that can be almost unbearably light, frustratingly anti-intellectual, woefully unspiritual, words have the ability to draw people to what matters most.

Martyn Lloyd-Jones on Preaching

The preacher must be a serious man; he must never give the impression that preaching is something light or superficial or trivial?.What is happing [in the act of preaching] is that he is speaking to them from God, he is speaking to them about God, he is speaking about their condition, the state of their souls. He is telling them that they are, by nature, under the wrath of God??the children of wrath even as others??that the character of the life they?re living is offensive to God and under the judgment of God, and warning them of the dread eternal possibility that lies ahead of them. In any case the preacher, of all men, should realize the fleeting nature of life in this world. The men of the world are so immersed in its business and affairs, its pleasures and all is vain show, that the one thing they never stop to consider is the fleeting nature of life. All this means that the preacher should create and convey the impression of the seriousness of what is happening the moment he even appears in the pulpit. You remember the famous lines of Richard Baxter: ?I preached as never sure to preach again, and as a dying man to dying men.??You remember what was said of the saintly Robert Murray McCheyne of Scotland in the last century. It is said that when he appeared in the pulpit, even before he had uttered a single word, people would begin to weep silently. Why? Because of this very element of seriousness. The very sight of the man gave the impression that he had come from the presence of God and that he was to deliver a message from God to them. That is what had such an effect upon the people even before he had opened his mouth. We forget this at our peril, and at great cost to our listeners.
