Peter Mead, at Biblical Preaching.Net, gives two options for turning a text into a half hour sermon in this article. Mead provides two options. The first is to carefully plan how to drive the main point into your people. This would include tactically deciding how you will present the idea. Mead succinctly summarizes this option as follows:
In the Winter 2003 edition of the African American Pulpit there is the sermon The Worms Got Him by Dr. Caesar Clark who is one of the great African American preachers.
We will look at this sermon at another time in that there is much in it to learn about the genius of the Black pulpit. What I want to look at here is the interesting device that Clark uses in his first move of the sermon. Here Clark summarizes a lot of information and background data for the hearers.
When you have a main question or a thesis, you need to translate that thesis into a sermon outline. There are Seven Interrogatives that you can ask of your thesis to help you flesh out an outline.
The final source of Biblical Preaching is imagination. Charles Koller notes that imagination alone can turn a dull sermon into one that comes alive. Imagination helps you create connections between the past and the present in interesting ways.
Charles Koller in the book How To Preach Without Notes writes: “Preaching at its best is the sharing of profound personal experience.” He backs up this claim by appealing to the apostles who simply told the story of their interaction with Jesus Christ (Acts 4:20).
