Gospel-Centered Preaching

Dan Cruver has written a three-part series on "The Functional Centrality of the Gospel" that is well-worth reading. A couple of his comments should give a succinct summary:

One of my main concerns for preachers and teachers of the Word is that the gospel would not merely have the stated centrality (i.e. “The gospel is central in all that we say and do here.”) but also the functional centrality in the life of the church.
. . .
I have become convinced that true gospel-centered preaching recognizes the necessity of demonstrating how every text finds its ultimate reference point in what God has accomplished in the Messiah.
