Book excerpt: He was the most influential man of his day. The movement that began with his posting of the Ninety-five Theses reshaped Europe, redirected Christian history, and recovered the truth of Gods word. Five hundred years later, what is Luthers legacy? In this volume, R.C. Sproul, Stephen J. Nichols, and thirteen other scholars and pastors examine his life, teaching and enduring influence. Meet Martin Luther, the mercurial Reformer who, out of love for the truth and the desire to bring it to light, set the world ablaze.
