Preachers are expected to “tell the story” in the African American tradition. Often this is a call to preach the familiar stories that we all have heard multiple times. Preaching familiar stories helps both the preacher and the people. The people know the story that you are seeking to interpret and the preacher does not have to go looking in obscure sections of the Bible for something to preach.
Peter Mead over at Biblical Preaching has a series going on Preaching without notes that I referred to in this post. In his first post he described why preaching without notes is a valuable method.
In the second post which can be found here, Mead emphasizes the HOW. Mead’s method can be summed up in one word, “internalization.”
