One reason many folks are clueless writers is that they don't think about definitions (frankly, many do not appear to think at all). If we cannot define what we are talking about, then what are we really saying?
Keeping this in mind, let's have a small group exercise. Let's define "church." It's helpful to do this in ten words or less. The word limit forces us to be precise in our thinking. So, can you do it? I think you can. Define "church" in ten words or less. Please leave your definition in the comments.
Here's my definition:
"A supernatural community on mission with Father, Son, and Spirit."
