Dr. David Allen has a good post discussing text-driven preaching and pragmatic textual analysis here. Make sure to read the entire post but see the conclusion below to whet your appetite.
"In summary, text-driven preachers will do their exegetical homework to determine what the text means. Text-driven preachers will engage in creative exposition to explain the meaning of the text to a contemporary audience. Text-driven preachers will seek to become master communicators with an understanding of their audience and communication techniques that will make for the most effective preaching of Scripture with the goal of life transformation effected by the Holy Spirit."
