Mrs. Spurgeon was fervantly praying for some opportunity to serve Christ, she was directed by the Lord to the establishment of what became a very central and important aspect of the Metropolitan Tabernacle ministry: the Book Fund.
The Book Fund had a providential beginning, as did most of Spurgeon’s benevolent enterprises. In the summer of 1875, Spurgeon completed his first volume of Lectures to my Students. He handed a proof copy to his wife and asked what she thought of the book. After reading it carefully, Mrs. Spurgeon declared that she wished she could place a copy in the hands of every minister in England. Quite casually Spurgeon said, “Then why not do so?” Without a moment’s hesitation she replied, “How much will you give?” It sparked an idea, and she prayed much about it to see if God might lead in the matter. Suddenly it dawned upon her that the money needed to launch such a project was already at hand. Susannah had a little habit of putting away in a drawer every crown piece that came into her hands. She counted the coins and found the amount would exactly cover the cost of sending out 100 copies of the Lectures. “In that moment,” she tells us, “though I knew it not, the Book Fund was inaugurated.”
