From Lewis Allen’s The Preacher’s Catechism – Q&A 23: What does the second commandment teach us? – You shall not make a preaching idol of your image or anyone else’s.
Here are some warning signs that you could be in danger of preaching idolatry:
You can never read the Bible for your own soul’s profit. It just doesn’t seem important anymore. Now you’re consumed with studying the Bible for the sake of others. In fact, when you do sit down to read your Bible, you actually start noting how you could preach the passage, and you’re halfway through preparing an out- line before you realize it. Maybe your soul is starting to shrivel just as your work expands.
You can never say no to a sermon. You get restless when you’re not preaching on a Sunday. You struggle to listen to the truth of a sermon, because instead you’re critiquing the sermon. You’re always looking for more opportunities to preach. Called you may be, and compelled to preach — well, that’s a given; but are you a preaching obsessive?The Preacher’s Catechism, Lewis Allen, Crossway, 2018, pg 126.
