On 31 October 1517, Martin Luther posted his ninety-five theses on the castle church door in Wittenberg – the starting gun for the Reformation. Five hundred years later, the issues debated at the Reformation are still urgent.

In this clear, incisive and accessible survey, Michael Reeves and Tim Chester show how the Reformation helps us answer questions like: How do we know what’s true? Can we truly know God? How does God speak? What’s wrong with us? How can we be saved? Who am I?

At its heart, the Reformation was a dispute about how we know God and how we can be right with him. At stake was our eternal future – and it still is.
