Charles Haddon Spurgeon (1834 – 1892) has proven to be one of the greatest preachers, if not the greatest preacher, since the days of the apostles. The appeal of Spurgeon’s preaching was almost immediate, and his Metropolitan Tabernacle was regularly filled with 5000-6000 people.
Steven Lawson summarizes the massive scope of Spurgeon’s ministry as seen in the volume of his published sermons and written works:
By 1863, Spurgeon’s sermons had already sold more than eight million copies. At the time of his death in 1892, fifty million copies had been sold. By the end of the nineteenth century, more than a hundred million sermons had been sold in twenty-three languages, a figure unmatched by any preacher before or since.
Today, this number has reached well over three hundred million copies. A century after his death, there were more works in print by Spurgeon than by any other English-speaking author. Spurgeon is history’s most widely read preacher. 
The incredible reach of Spurgeon’s preaching was by no means attained by peddling a shallow Gospel. Instead, one is struck by the theological richness of Spurgeon’s sermons. He did not waste time on trifles, and he did not neglect difficult doctrines. In Spurgeon we find an example of the pastor-theologian that has yet to be matched.
