Dr. Sproul's commentary on the Gospel of Matthew, published by Crossway Books, is a hefty hardback of over 800 pages and 129 chapters. It consists of expository sermons that Sproul preached over Matthew's Gospel. It is part of a series by Sproul called St. Andrew's Expositional Commentary. Other commentaries in the series include studies through Acts, Romans, and 1 & 2 Peter.
Sproul is an extremely gifted communicator. Sometimes, Reformed preachers have dug so deeply in the mines of theology that they cannot speak to normal audiences, including both churched and un-churched people. Sproul is no backwoods fundamentalist. He got his doctorate at the Free University of Amsterdam, which was the center of academic Reformed scholarship in the 20th century. Sproul taught theology at various seminaries, but he is best known for his work at Ligonier Ministries. But in spite of his degrees, his years inside the classrooms of seminaries, and his studies, he is an effective and popular communicator.
After decades of writing, publishing, presenting recorded lectures and teaching, Dr. Sproul turned his ministry labors toward pastoring a church. Along with his many books on theology, practical Christian living, introductory philosophy, and cultural engagement, he is publishing his sermons on books of the Bible.
Sproul does not do in-depth explications or studies in the texts of Matthew. The person wanting more of the theological detail would need to look elsewhere. (I find William Hendriksen's commentary on Matthew very helpful, and I just acquired Leon Morris' work, and Charles Spurgeon did a commentary on Matthew.) Anyone wanting to read more extensive sermons would do well to read Daniel Doriani's 2 volumes or John MacArthur's 4 volumes.
What Sproul does best is to give a short, thought provoking, convicting sound look at the text. His book is excellent for a morning reading. It would work for family time. It is great for the person who is not theologically well grounded, but does not want fluff. It works for the man in a hurry or the woman with too many kids and not enough time. It is good for beginners; it is a good refresher for long-time Bible students.
Sproul presents good morning theology. You will pick up on a number of key figures in history--both church and secular history. You will better understand the texts. You will see applications of the Gospel to everyday life and to the broader culture. You will find doctrine, correction, reproof, and instruction (2 Timothy 3:16).
Since December (2012), I have been preaching through Matthew. Now (June 2013, 26 sermons into the series, I am working slowly through the Sermon on the Mount. Now, just beginning chapter 6, I will be working even more slowly through the Lord's Prayer (or the Model Prayer). Sproul has nine sermons on the Lord's Prayer. I usually read Sproul early in the week, just to help bring the coming week's text into focus. And often, later in the week, after I have plowed through some other fine books, I go back to Sproul again.
I really enjoy and heartily recommend this book and any others from the series.
