Imagery without Images

I've been challenged this month. I'm preaching at the Maui Church of Christ, and they don't have a projector for me to use. I'm without PowerPoint for all of my sermons and classes. Because of that I've been reworking my sermons to provide imagery in the stories.

Brain Rule #4 tell us that: "You’ve got seconds to grab someone’s attention, and only 10 minutes to keep it. At 9 minutes and 59 seconds, something must be done quickly—something emotional and relevant." (from Brain Rules by John Medina - affiliate link)

So every ten minutes or so I try to make a strong, visual point in my sermon. Instead of saying: it's like buying a used car. I tell a story about walking into a car dealership and drinking the stale coffee and waiting while the salesperson "talks to their manager" somewhere. It's a relate-able, vivid, detailed story that allows the audience to build their own visual connection.

How can you build vivid imagery without images?
