"Preaching about the Gospel isn't preaching the Gospel"

The following is a repost of an episode aired on "Christendom and the World". See the link below. In this episode, the Rev. Schlies sit down with Rev. Andrew Preus to discuss the cliche that "preaching about the Gospel isn't preaching the Gospel". What is the role of teaching in the sermon? And, why is it necessary to instruct in God's word as well as apply it?
