Charles Spurgeon preached to something like ten million people in his lifetime, sometimes speaking ten times a week at various locations. His sermons were transcribed as he spoke. In those days of telegraph, his messages became available across the Atlantic, in America, within days, and around the world within a week. Besides his amazing quantity of sermons, he wrote an autobiography, the massive The Treasury of David, 3 Volumes on the psalms, books on prayer, the classic devotional Morning and Evening, and produced a magazine, The Sword and the Trowel. Some argue that no author in history has more material in print than Charles Haddon Spurgeon.
