Against great obstacles William Wilberforce, an evangelical member of Parliament, fought for the abolition of the African slave trade and against slavery itself until they were both illegal in the British Empire. In this concise volume, John Piper tells the story of Wilberforce's transformation from an unbelieving young politician into a radically God-centered Christian and how his deep spirituality helped to change the moral outlook of a nation. Audio Book is read by Wayne Shepherd.
