Book excerpt: Preaching – described here in Johan Cilliers’s groundbreaking new book as the heart and soul of the church – requires both constant revision and fidelity to principles. Hence this book’s subtitle: “Revisiting the basic principles of preaching”. From various theoretical and practical viewpoints, Cilliers critically examines the state and future of preaching and deals boldly with contentious issues such as the validity of legalistic and moralistic preaching.
