Book excerpt: As the major motion picture hits theaters this spring, the best-selling coauthors of the Finding God series explore the true story of how God'TMs amazing grace ended the British slave trade. With profound reflections drawn from the lives of two men, William Wilberforce and John Newton, who wrote the beloved hymn, the authors reveal God'TMs grace in our everyday struggles and show how he uses even the smallest of events and weakest of individuals to implement his grander plan in this world.
