The best way to write a sermon?
It means On Your Feet Out Loud.
It’s a term used by speaking coach Ken Davis. (kendavis.com)
Speaking the sermon out loud as you write helps you develop a sermon designed for the ear, rather than eye — a sermon better heard than read.
You may run-on the occasional sentence — something you’d never do in an academic paper or magazine article — but your listener will be able to follow you, because you’re writing with the spoken presentation in mind.
Besides, don’t we all think better on our feet?
