I was privileged to grow up under the ministry of probably the greatest visionary I have ever personally known.  His name was Dr. Bradley Price, and he came to Northside Baptist in Charlotte in 1990.  The Charlotte Observer reported on our big days at Northside, where 8,000 people would gather for the Spirit of Christmas service and receive a hot-cooked free meal.  Through my experiences with Dr. Price as a child, a youth, one called to ministry, and then a ministry intern, glory to God, I caught from him the passion for and ability to dream, to crystallize a vision, and to inspire others to see the dream also.
I just sort of thought everyone had that same passion and ability.  One day, I was sitting in a circle of pastors, and we were picking each other's brains for ideas and supporting one another in prayer.  One of my pastoral brothers asked, "Can anyone help me develop a vision for my church?  I've never been taught how to do that."  If a pink elephant had jumped up on the desk, I may not have been more surprised.  I just thought everyone knew this.  
Over the years, I have come to learn that the ability to "see" a vision for an organization, for a church, for a people, for a community and region, is something that is caught.  Sure, you can go out and buy Andy Stanley's book and others, but translating principles into practice is easier said than done.  Therefore, when it comes to recruiting and identifying leaders, and also hiring staff, look for those who demonstrate the ability to dream, to cast vision, and to build consensus around the dream.  I'm blessed that my Assistant Pastor has this ability, and, Lord willing, the successful candidate for the next pastoral position we fill will have it also.
Not long ago, I was speaking with a minister whose organization is thinking about buying our church property which is for sale.  As we talked together, it struck me.  This man has the ability to develop a vision.  It had been a long while since I had talked with someone in ministry with that ability, and it was so refreshing.  Such people are cut out of a little bit different cloth, it seems.  And if you have this ability, mentor others, so that they can catch it also.

This post goes a bit deeper than the basic reminder that, as leaders, we need to communicate our expectations and communicate them clearly.  You probably have that part down.  I find, though, that it is easy to stop there -- and that's not enough.  Not only must we communicate what we do want; we must communicate what we don't want.  
With the diverse backgrounds of our followers along with different educational attainment, hearing ability, predisposition toward cooperation or not, and so much more, twenty people can hear the exact same presentation and draw at least twenty different conclusions.  In fairness, we cannot anticipate every ditch people may stumble into, but investing a few moments to consider this can save you time and headaches down the road.  
Consider an example.  Our church recently added a staff member.  We wanted to give that staff member purchasing power, so we asked the bank to generate a credit card for him with "the same information" as the card that I carry as pastor - same billing address, same credit limit, same fact pattern.  Months later, we learned that the bank had generated a credit card sharing the credit limit with the card I carry (which is typical procedure we now know).  We thought we had clearly communicated that we wanted an additional amount, raising the overall organizational credit limit to accommodate, but the term "same" led all of us into a ditch.  
Trust me - I could share dozens of other examples, but for a variety of professional reasons, it would be unethical for me to do so.  Bottom line: Think through a couple of possible corruptions of your message, and kindly communicate that those corruptions are not what you are after.

An angle that few if any seem to take is to examine the issue from the perspective of overall church unity.  It just so happens that I am guiding my church through 1 Corinthians in this modern situational context; so church unity is obviously on the brain.  Two questions emerge: (1) Can you have spiritual unity without political unity? and (2) What does preserving spiritual unity look like in such a politically divisive age?
