Between Two Worlds

I remember being moved by this meditation the first time I heard it years ago. Now it's featured on the DG blog page:

Why do adult bookstores and strip clubs cover their windows? The obvious answer is so you can't see in. But is there more to it than that?

Listen to John Piper suggest why they really don't want windows--and then offer a way to defeat lust that you may not have thought of.
