I once shared this story with Dr. Warren Wiersbe, who was a great admirer of Charles Haddon Spurgeon, considered by many to be the 19th century’s greatest preacher. Even though Wiersbe had written of Spurgeon and probably knew as much about the man as anyone, he was unfamiliar with the story.
The source is an 1898 book, The Unexpected Christ, by Louis Albert Banks.
The chapter in which the story is located is headed, “Christ Cleansing the Temple of the Soul,” based from Luke 19:45-46.
“Mr. Spurgeon said that in his young ministry he received a tremendous spiritual uplift which was felt through all his later life by a strange revelation which came to him in a dream.
“He was sitting in an armchair, wearied with his work. He had fallen asleep in a very self-complacent sort of mood, as his work at the time was unusually successful. As he slept he thought a stranger entered the room, and though his face was benign, he carried suspended about his person measures and chemical agents and implements, which gave him a very strange appearance.
“The stranger came toward him, and extending his hand, said, ‘How is your zeal?’
“Mr. Spurgeon supposed when he began his question that the query was to be for his health, but was pleased to hear his final word; for he was quite well pleased with his zeal, and doubted not that the stranger would smile when he should know its proportions. Instantly he conceived of it as physical quantity, and putting his hand into his bosom brought it forth and presented it to the stranger for inspection.
“He took it and placed it in his scales, weighing it carefully. Mr. Spurgeon heard him say, ‘One hundred pounds!’
“He could scarcely suppress an audible note of satisfaction; but he caught the visitor’s earnest look as he noted down the weight, and he saw at once that the man with the scales had drawn no final conclusion, but was intent on pushing his investigation.
