Translated to English from German, Justification as the Formative Power of Mission by Georg Vicedom tackles the question what is the point of mission work? Vicedom claims that the goal of missionary work is saving people—it's not just a perk but the entire goal of going out into the field. He points out bad motives for mission work throughout history before pointing you back to the foundational doctrine of justification as the framework for missionary work. Pastors and laypeople alike, especially those considering mission work, will find this volume useful to help understand justification and their call from God in the world.
