This short book, magnificently researched, brings a wealth of insight into one of the most important figures in modern church history, Charles Simeon (1759-1836), a contemporary and friend of William Wilberforce, who was vicar of Holy Trinity Church, Cambridge, for over fifty years. He left an indelible mark on the Church of England, and on world mission, and his legacy stretches down to us today. Intervarsity/USA, Inter-Varsity Canada, and the American and Canadian Bible Societies trace their roots back to him. More than 150 years later, John Stott would say that Simeon taught him to preach.
