Each week when I preach, I write out a whole text, but I don't bring it with me into the pulpit. I have found that, if I know well the biblical texts and the sermon that I have written, a few bullet points are enough to keep me on task. That way, I can connect with the congregation, react to them, listen for the Holy Spirit, and adapt the sermon as I go along.

Sure, it's risky. Occasionally, I'll get to a point where I cannot remember what I intended to say next—a sign that I'm slavishly tied to the text—but eventually I find my way back. Worse, every once in a while I will say something I did not intend—something that, if given the chance to take it back, I would. Several months ago, when rattling off a list of empty, idolatrous practices, "going to church" popped out of my mouth, and I wanted to say, "Wait, I didn't mean that!" but it was too late. Sure enough, one person told me that was her favorite part of the sermon. (Sigh. Of course it was.)

Going off script can be dangerous. Preachers say things that they regret. Candidates make promises that they can't keep. Parents use words that they hope their children won't remember even though they know that they always do. And, in Sunday's Gospel lesson (Luke 9:51–62), Jesus makes a comparison that he surely did not intend. A would-be disciple approaches Jesus and says, "I will follow you, Lord; but let me first say farewell to those at my home," and Jesus responds, "No one who puts a hand to the plow and looks back is fit for the kingdom of God."
