Pastors: "What Is the End of What You Are Doing?"

That's the question William Still asks in his excellent little book The Work of the Pastor :

To save the sheep from wild beasts and all other dangers is not to feed them; and if they are not fed, what matters whether they are safe or not? What is the good of being saved to starve? We must be saved in health and strength, unto maturity and power to reign with Christ in His Kingdom. And for that we must be fed. Every temptation to be sidetracked from the task of eternity which is the task of the hour--your hour--must be seen in relation to the finished product. What is the end of what you are doing? The God-appointed end?
