What is preaching? Why is some preaching arresting and powerful, and some boring and fl at? How do you prepare sermons? The author states that God’s work in the world and preaching are intimately linked, ‘The kingdom of God and preaching are like conjoined twins who cannot be separated; they stand or fall together.’ This book is based on the author’s preaching seminars held over the years in Switzerland, England and Wales, while additional material is taken from lectures at the Evangelical Theological College of Wales, Bryntirion, Bridgend. The author insists that a sermon should be rooted in accurate exegesis, characterized by doctrinal substance, Christ-centredness and supernatural authority, as well as being clear, direct, vivid, helpful and moving. His book explains why.
