As Dr. Harry A. Ironside preached one day, he noticed a man in the crowd writing on a card, which he presently handed to the speaker. The man was Arthur Lewis, an agnostic lecturer, and he proposed a challenge to the speaker to debate the subject, “Agnosticism versus Christianity,” and offered to pay all expenses involved.
Dr. Ironside read the card aloud to his audience and then said: “I accept on these conditions:
“First, that you promise to bring with you on the platform one man who was once an outcast, a slave to sinful habits, but who heard you or some other infidel lecture on agnosticism, was helped by it and cast away his sins and became a new man and is today a respected member of society, all because of your unbelief.
“Second, that you agree to bring with you one woman who was once lost to all purity and goodness, but who can now testify that agnosticism came to her while deep in sin and implanted in her poor heart a hatred of impurity and a love of holiness, causing her to become chaste and upright, all through a disbelief in the Bible.”
“Now, sir,” he continued, “if you will agree, I promise to be there with one hundred such men and women, once just such lost souls, who heard the gospel of the grace of God, believed it and have found new life and joy in Jesus Christ our Saviour. Will you accept my terms?”
As might be expected, the atheist could only walk away silently.
