It shouldn't be possible to talk about the Reformation without talking about the gospel. Martin Luther's discovery has fascinated artists, inspired reformers, envisioned abolitionists, and given beautiful hope to millions. It has changed the world -- and continues to do so. Michael Reeves serves the church in this 500th-anniversary year by writing an evangelistic resource that tells the story of that discovery, draws out its effectiveness and beauty, and speaks of its consequences for the history of the world. On this 500th year since the beginning of the Reformation, this small but powerful resource enables you to capture the historical moment effectively to carry on the work of Reformation: to get the story of the gospel to world.
