It’s no secret that theologians can be fairly bad, if not horrible writers. One of the exceptions to that rule is Tony Jones of “Theoblogy.” Jones lists his writing habits in a recent post. I think every writer can benefit by incorporating these basic rules of writing.
For a more thorough treatment of these practices, I recommend: On Writing Well by Zinsser and of course the Elements of Style: two must-reads for every writer. Check that. They are must not only be read but practiced.
