How to Hear a Sermon
I have another good audio series to recommend. PCA pastor Robert Rayburn gave these lectures on the ministry of the pulpit to the students of Covenant Theological Seminary about 10 years ago.
He covers a lot of ground, including some topics that are seldom discussed like the benefits of having the same pastor for many years. Similarly, he corrects the common view that "the priesthood of all believers" negates the special office of the pastor.
In a lecture on "Preaching as Mystical Event" he explains the reformation understanding that it is through faithful preaching (not "quiet time", etc) that we most often and most powerfully hear the voice of God. New to me was the idea of "preaching the poles", where he exhorts pastors to preach the tensions of Scripture. For instance if the text for that week includes Christ's statement that He will judge us based on the good or bad that we have done, do not give into the temptation to work justification by faith alone into the sermon. If that confuses you, listen to the lecture to get a whole idea.
What struck me the most was a survey he mentioned where several hundred PCA pastors were asked what Books of the Bible they had preached from in the last three years. Something like 95% had preached from the Gospel of John, and only a small portion had been in the Old Testament at all. Pastor Rayburn powerfully pointed out that the Canon of the PCA has gotten much smaller. This is largely due to pastors who switch pulpits frequently and the loss of the second service on the Lord's Day.
Thanks to Pastor Mark Horne for the link.
