A good friend of mine dropped out of seminary, entered the business world, became a successful executive recruiter and migrated finally to management consulting, at which he is an expert. Big corporations retain him to help them think imaginatively about their businesses. One of his activities is assisting business leaders in writing mission statements that enable everyone, from CEO to maintenance worker, to understand the primary purpose of the enterprise.
In other words, he is in a very real ministry. One of his rules is that whatever the size and nature of the enterprise, the mission statement must never exceed 75 words. (Preachers throw away 75 words clearing their throats or moving from one paragraph to the next.)
