i found this idea intriguing and incredibly inspiring! i have been in church leadership now for a good number of years and have always been taught and operated under the premise that to be effective, you have to have a single, succinct "vision statement." i've often wrestled with this,though, without being able to describe it in such a way, because it seems so difficult to convey all that needs to be conveyed in a single statement.
reising goes on to say, this is no way alleviates the need to communicate the vision or to write it out in detail... in fact, in many ways, it enhances that need. people need to see the elaborate picture you see in order to get excited about it, buy in and be a part of fulfilling that vision. if the picture is fuzzy, unclear and unfocused, people will be fuzzy, unclear, unfocused and both they and you, will likely become frustrated.
as God said to the prophet habakkuk, "write the vision and make it plain..."
