Harry Ironside, a well-known preacher of yesteryear, was once challenged to a public debate by Arthur Morrow Lewis, a well-known unbeliever. The subject was to be “Agnosticism versus Christianity.” Ironside accepted the challenge with one condition: and that was that Lewis should bring with him one person who had been addicted to alcohol and one person who had been enslaved in depravity, and who were now freed from their past because their lives had been turned around by unbelief. And if he did produce two such persons, Ironside promised to bring one hundred people who were once just such lost souls and had found new life and joy in Christ Jesus. Well, it was the agnostic who pulled out of the debate.
