The saying goes that those who don't know history are doomed to repeat it. Make sure you learn the lessons of church history with these books that take you deep into the history of Christianity. You'll meet the great heroes of the faith who were shepherding the church long before the present day—the ancients, the medievals, the Reformation leaders, and all the celebrated figures like Jonathan Edwards, C.H. Spurgeon, and D.L. Moody, who will never be forgotten in church history.
