Preachers determine the meaning of scripture so that they can convey that meaning to the congregation in the preaching moment. Preachers go to considerable lengths to make sure that they preach the truth and not error. They study the passage within the context of the chapter, book, and even the whole cannon of scripture. In many cases, the preacher derives valid and truthful points from the text and then present those vital truths to the people. This is good, but often when you take the points from the story, you remove the ability of the people to fully experience the truth that you are presenting. But before the people can experience the text, we have to both understand and experience the text ourselves.
But how do you experience the text? Well you should do a full exegesis as you have done in the past, but I would also suggest that you might allow all of your senses to guide your understanding of the text. Yes, allow all five senses of touch, sight, sound, smell, and taste to help you ask questions of the text that you are presenting.
