A couple of days ago, I provided an extended quote from
William Bruinsma's recent article entitled, "The Minister's Development of His Preaching after Seminary." Here is another quote worth considering.
"There are a few practical methods that ministers can use to develop in their preaching. The first means is one that is pounded into the head of every seminary student: read! Obviously, when a pastor reads, he is exposed in his reading to different ideas and different styles of conveying the Word. Depending on what books we are reading—and we need to read a wide variety of books—we can learn how to improve both the delivery and content of sermons. Doctrinal books will help improve our understanding of the doctrinal issues afloat in our present church world. Books of a practical nature will help us develop in our ministry at large, but also in our ability to feed the sheep. There are pastoral books, books on missions, books on church history, church polity, doctrine, social issues, and so the list can go on. We need to read. That is a must in our development as preachers.
"The ability to read varies from one pastor to another. Some can zip through a book swiftly and effortlessly, while others take more time to read a book. The retention of some is beyond that of others. Even in this area talents vary. Some can read a book in hours; for others it may take a few days. But that ought never deter the pastor from reading. Reading is the chief means of development in our preaching."
