Most Christians know John Newton as a man who once captained a slave ship, was dramatically converted to Christ on the high seas, and later penned one of the greatest hymns of the faith, "Amazing Grace." But he also had a huge impact on his times as an icon of the evangelical movement, as a great preacher and theologian, and as a seminal influence on abolitionist William Wilberforce. Newton's friendship with Wilberforce is portrayed in the major motion picture Amazing Grace. Jonathan Aitken's new biography John Newton explores all these facets of Newton's life and character. It is the first biography to draw on Newton's unpublished diaries and correspondence, providing fresh insight into the life of this complex and memorable Christian. The result is a fascinating, colorful, and historically significant portrait of John Newton, a self-described "great sinner" redeemed by a great Savior through amazing grace.
