John Piper's short eBook biography of the most famous figure of the Reformation, Martin Luther, gleans important lessons from Luther's life and work. Piper points out that Luther had a true love for the Bible as a book and as the final repository of God's Word, over and above the claims of any council or leader. Luther cultivated a love for the Bible by constant and regular study. This love for the Bible drove Luther to break with the Catholic Church and begin the Protestant Reformation. Piper makes Luther's life relevant to our own lives by making connections between what Luther did and how we live our lives.
