This is the final inaugural address delivered by Charles Haddon Spurgeon at the College Conference in April 1891. This book is an encouragement to every modern warrior engaged in the crusade against error and sin. It was published after Spurgeon's death as The Greatest Fight in the World. Later the subtitle Final Manifesto was added.

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.
