We are not indispensable
It is a good test to the rise and fall of egotism to notice how you listen to the praises of other men of your own standing. Until you can listen to the praises of a rival without any desire to indulge in detraction or any attempt to belittle his work, you may be sure there is an unmortified prairie of egotistic impulse in your nature yet to be brought under the grace of God.
Success exposes a man to the pressure of people and thus tempts him to hold on to his gains by means of fleshly methods and practices, and to let himself be ruled wholly by the dictatorial demands of incessant expansion. Success can go to my head, and will unless I remember that it is God who accomplished the work, that He can continue to do so without any help, and that He will be able to make out with other means whenever He cuts me down to size.
The missionary who has raised a church to believe that he is indispensable has done the church an injustice. From the earliest days of the work, the missionary should be planning on working out of a job. National leadership needs to learn how to depend on the Lord, how to train its own spiritual leaders, and how to take responsibility for the work.
Every preacher ought to be primarily a prophet of God who preaches as God bids him, without regard to results. When he becomes conscious of the fact that he is a leader in his own church or denomination, he has reached a crisis in his ministry. He must now choose one of two courses, that of prophet of God or a leader of men. If he seeks to be a prophet and a leader, he is apt to make a failure of both. If he decides to be a prophet only insofar as he can do without losing his leadership, he becomes a diplomat and ceases to be a prophet at all. If he decides to maintain leadership at all costs, he may easily fall to the level of a politician who pulls the wires in order to gain or hold a position.
