Your questions need to help the guest preacher warm up and introduce themselves and they need to help the congregation warm up and get to know the speaker.
People bring up rollerblading when interviewing me at events and it rarely ever works. It’s a hospital pass. Because they rarely give contact for WHY they have suddenly brought up rollerblading. And they haven’t really thought of an actual interesting question. As a result I’m left having to do all this work to save an awkward out of context in-joke.
Worse still, it makes me look somehow as if I’m the weird one… as if I asked to be asked about rollerblading or something!
Actually, I’d rather not get interviewed before I preach, but instead just get a brief introduction (again without any odd, unexplained references to rollerblading).
But if you’re going to ask questions, make sure you actually think through what will be good questions!
