This idea is not original to me. I heard Anthony Mangun speak of his strategy in this regard; later I read of something similar in one of Warren Wiersbe’s books. This was developed into a chart that I kept in the front of my Bible that I used to record the name of the sermon and the date I preached it. My list included the following topics I wanted to preach about. This was helpful because there are certain topics that do naturally flow from so
Communion Overcoming the Flesh
Exalting Jesus Revival
There are also special days that have the potential for specific preparation. Such events: Easter, Christmas, Pentecost Sunday, Baby Dedications, Mother=s Day and Father=s Day
You can use something similar in preparing evangelistic sermons. (Such a list is available in Masterful Preaching by the author; Truth Publications, Inc.) This sort of planning gives structure to the process of study.
