Here are a couple of good quotes from a book I am reading entitled Doctrine that Dances: Bringing Doctrinal Preaching and Teaching to Life. It is written by Dr. Robert Smith, professor of preaching at Beeson Divinity School (a couple of years ago I mentioned Dr. Smith here). The quotes are seeking to define what doctrinal preaching is:
As Jesus admonished that the Scriptures be searched because they testify of Him (John 5:39), preachers of Christian doctrine make Christ the heart of their preaching. If the Bible is read backwards, one will see that Jesus Christ, the Lamb of God, was slain from the foundation of the world (Rev. 13:8). This means that in the mind of God, Calvary was a forethought and not an afterthought. God did not react to the fall of Adam and Eve, but rather He pre-acted before the the fall of Adam and Eve. The Old Testament proclaimed that Christ is coming. The New Testament announced that Christ has come and will come again (p. 23) Doctrinal preaching must have an object. We cannot have faith in faith; we do not worship worship; and doctrine does not exist fro doctrine's sake. Doctrinal preaching carries out the mission of magnifying Jesus Christ (p. 25).
The book is so far so good. I am enjoying the read. You may want to consider the investment.
