That fact is, says Andy Stanley, people can leave whenever they desire. We have no way of forcing them to do what we want. Our only real power is the influence they grant us in their lives. And that influence will be destroyed if we live without integrity. That is why "moral authority" is so central to spiritual leadership. When people see a gap between what we say and what we do, it erodes our moral authority and ability to influence their lives. And once it's gone, there isn't a leadership principle in the world that is going to fill the void.
