The following is a quote from “Leading With A Limp” by Dan Allender
The difference between a manager and a leader is the internal urge to alter the status quo to create a different world. In that sense leaders are prophets. They see the present as incomplete and inadequate and are willing to risk the comfort of the present for the promise of a better tomorrow. A manager, on the other hand, is content to keep the organization running as smoothly and efficiently as it can function. A manager serves to keep the plane in the air, whereas a leader wants to put a new engine on the plane midair.
A manager wants to approach the inevitable chaos with the tried and true methods that have worked in the past. In contrast, a leader knows that as difficult as it is to bring about change, not to do so will destroy the community. There can be no freedom from the bondage of the daily rut without the chaos that comes from leading people out of the status quo.
A leader who desires nothing more than the status quo becomes an ostrich with its head in the sand. A leader must be troubled and discontent, and he must ask the question, How can tomorrow be better than today? He must be a visionary, living in the tension between how to honor what is good and true today and yet be discontent with today in light of what could transpire tomorrow. He is torn between what is and what could be, yet he speaks the future into the present due due to his compelling desire for change. P. 58
