I like the following definition…adding it to this running commentary about the topic on the blog.
“‘Missional’ is not an event we tack onto our already busy lives. It IS our life. Mission should be the way we live, not something we add onto life: “As you go, make disciples.”; “Walk wisely towards outsiders”; “Let your speech always be seasoned with salt”; “be prepared to give a defense for your hope.” – Jonathan Dodson
