This was a very different talk than that of John Piper. Although Piper’s talk has received much of the attention due, I suspect, to his focus on the style of preaching that is required, and also to the evident passion in his sermon, I am convinced that this talk by Duncan is every bit as important!
In fact, this sermon probably challenges our practice as much as Piper’s. For if John Piper’s talk makes us realise that we need to radically address our style, and more than that, our heart attitude towards preaching, this talk challenges us to address the very content of our sermons.
Duncan began by highlighting just how few of those present were at that time preaching through a book of the Old Testament. Indeed, as is often the case, most of the participants who were systematically preaching through a book were in an epistle. Duncan challenged us to remember that it is ALL of scripture that is inspired for our instruction. It is important to note that whilst there is evidence that New Testament books were beginning to be recognised as scripture even in apostolic times, when Paul and others commend the scriptures to us they are, of course, primarily referring to the Old Testament.
One of the things that struck me about Duncan’s sermon was the masterful way he demonstrated that the messages of the Old and New Testaments are entwined. A specific example stood out for me as a preacher: I loved the way he read the list of David’s mighty men, and pausing for effect, included Uriah the Hittite in a way that made you realise how shameful David had been to him even before Lig explained that. This moment reminded me of the way people said Dr. Martyn Lloyd-Jones could expound scripture just by reading it aloud! Lig pointed out that where the mighty men are listed their devotion for David is made clear, and then asked, “Did David show such devotion for Uriah?
