The strongest argument for the Gospel of Christ is the personal testimony of someone whose life has been changed by it. Charles Bradlaugh, an avowed infidel, once challenged the Rev. H.P. Hughes to a debate. The preacher, who was head of a rescue mission in London, England, accepted the challenge with the condition that he could bring with him 100 men and women who would tell what had happened in their lives since trusting Christ as their Savior. They would be people who once lived in deep sin, some having come from poverty-stricken homes caused by the vices of their parents. Hughes said they would not only tell of their conversion, but would submit to cross-examination by any who doubted their stories. Furthermore, the minister invited his opponent to bring a group of non-believers who could tell how they were helped by their lack of faith. When the appointed day arrived, the preacher came, accompanied by 100 transformed persons. But Bradlaugh never showed up. The result? The meeting turned into a testimony time and many sinners who had gathered to hear the scheduled debate were converted.
