Preaching familiar stories, provide a benefit to both the preacher and the people. The people already know the story that you are seeking to proclaim. In addition, the preacher does not have to go looking in obscure sections of the Bible for something to preach. In addition as Bishop Rudolh Mckissick wrotes: it will "increase [the people's] comfort as they listen to you."
But if we are to preach familiar stories, we must listen to Mckissick and attempt to "give the 'old text' a 'new spin.'" That is not to say, make up something, but find something dormant in the text that needs unearthing.
Eugene Lowry, in the book The Homiletical Plot writes about how to find this "new spin." Lowry suggests that preachers "Attend to every 'insignificant' line." He is telling preachers that when they preach the familiar stories, don't immediately jump towards the features of the text that you have heard preached repeatedly. Instead, go to those aspects that might otherwise be considered "insignificant." Look at the text very closely. Look at every word. Often the preacher can discover an important sermon from looking more closely at the text.
I must repeat that I am not talking about pulling words out of context and building a sermon based on that misunderstanding of the text. I am talking about looking deeply at the text and finding aspects of the text that have not been explored as much.
Lowry gives the example of Nicodemus coming to Jesus "by night." I admit that I have heard preachers build sermons on this feature of the text, but it does serve to demonstrate that small features of the text that might otherwise be considered insignificant can be very important and even guide a sermon.
Great preaching is not merely reading for surface, but it includes looking deeply at even those aspects that seem insignificant. If the Bible writer chose to put it in the narrative, then it is truly worthy of exploration.
My fellow preachers. It is in the details where we find very important features that can strengthen our sermons immensely. Look at these details in your attempt to give that "new spin" to an "old text."
