The Gospel of the Kingdom: A Popular Exposition of the Gospel of Matthew is Charles Haddon Spurgeon's only complete commentary of a New Testament book; with his only other commentary being The Treasury of David. He devoted two winters spent in the South of France to the production of this exposition. It was nearly finished when Spurgeon died. It was completed from his own spoken and written words (previously transcribed), by Mrs. Spurgeon and Mr. J. W. Harrald, his secretary; together they finalized several more of his works posthumously.

Charles Haddon Spurgeon (1834-1892) converted to Christianity at the age of fifteen. By the age of twenty-two, he was the most popular preacher in England, and remained so for the latter half of the 1800s. He frequently spoke to crowds over 10,000 in the days before electronic amplification. Known as the "Prince of Preachers," he delivered nearly thirty-six hundred sermons throughout his life. A prolific writer as well, many of Spurgeon's works remain in print to this day.
