There may not be a better example in the New Testament of what pastoral preaching is meant to be than the book of Hebrews. People have long recognized that the book of Hebrews is rhetorically powerful. There is something about this book, the way that the words are arranged and delivered, that lets us know that it was meant to be heard. It was meant to be expressed audibly.
I say it is a great example of pastoral preaching because it is theologically rich and yet intentionally purposeful and personal. It is a reminder that people are shepherded through the most practical issues of life by the teaching of deep and sound doctrine. In fact, the argument that drives the purpose of the letter is that Jesus is better than everything. It is the absolute preeminence of Jesus Christ.
