Early in his ministry the great evangelist and Bible teacher, Harry A. Ironside, was living in the area of San Francisco working with a group of believers there called "Brethren."  On Sunday as he was walking thru the city he came upon a group of Salvation Army workers who were holding a meeting on the corner of Market and Grant Avenues.  There were probably about 60 of them. When they recognized Dr. Ironside, they immediately asked him if he would like to give his testimony.  He did. 

As he was speaking, Ironside noticed that on the edge of the crowd there was a well-dressed man who had taken a card from his pocket and had written something on it.  As Ironside finished his talk this man came forward, lifted his hat, and very politely handed him the card.  On one side was his name which was immediately recongnizable.  The man was one of the early socialists who had made a name for himself lecturing, not only for socialism but also against Christianity.  As Ironisde turned the card over, he read, "Sir, I challeng you to debate with me the question, 'Agnosticism versus Christianity' in the Academy of Science Hall next Sunday afternoon at four o'clock.  I will pay all expenses." 

Ironside reread the card aloud and then replied somewhat like this...."I will be glad to agree to this debate on the following conditions; namely, that in order to prove that Mr._____ (will call him Ock)  has something worth fighting for and worth debating about, he will promise to bring with him to the hall next Sunday two people, whose qualifications I will give in a moment, as proof that agnosticism is of real value in changing human lives and building true character.

"First, he must promise to bring with him one man who was for years what we commonly call a 'down and outer.'  I am not particular as to the exact nature of the sins that had wrecked his life and made him an outcast from society-whether a drunkard, or a criminal of some kind, or a victim of his sensual appetite-but a man who for years was under the power of evil habits from which he could not deliver himself, but who on some occasion entered one of Mr. Ock's meetings and heard his glorification of agnosticism and his denunciations of the Bible and Christianity, and whose heart and minds as he listened to such an address were so deeply stirred that he went away from that meeting saying, 'Hence-forth, I too am an agnostic!' and as a result of imbibing that particular philosophy found that a new power had come into his life.  The sins he once loved, he now hates, and righteousness and goodness are now the ideals of his life.  He is entirely a new man, a credit to himself and an asset to society-all because he is an agnostic.

"Secondly, I would like Mr. Ock to promise to bring with him one woman-and I think he may have more difficulty in finding the woman than the man-who was once a poor-wrecked, characterless outcast, the slave of evil passions, and the victim of man's corrupt living...perhaps one who had lived for years in some evil resort....utterly lost, ruined, and wretched because of her life of sin.  But this woman also entered a hall where Mr. Ock was loudly proclaiming his agnosticism and ridiculing the message of the Holy Scriptures.  As she listened, hope was born in her heart and she said, 'This is just what I need to deliver me from the slavery of sin!' She followed the teaching and became an intelligent agnostic or infidel.  As a result her whole being revolted against the degradation of the life she had been living.  She fled from the den of iniquity where she had been held captive so long; and today, rehabilitated, she has won her way back to an honored position in society and is living a clean, virtuous, happy life-all because she is an agnostic.

"Now," he said addressing the gentleman who had presented him with his card and the challenge, "if you will promise to bring these two people with you as examples of what agnosticism can do, I will promise to meet you at the Hall at the hour appointed next Sunday, and I will bring with me at the very least 100 men and women who for years lived in just such sinful degradation as I have tried to depict, but who have been gloriously saved through believing the gospel which you ridicule.  I will have thse men and women with me on the platform as witnesses to the miraculous saving power of Jesus Christ and as present-day proof of the truth of the Bible." 

Ironside then turned to the Salvation Army captain, a girl, and said, "Captain, have you any who could go with me to such a meeting?" 

She exclaimed with enthusiam, "We can give you forty at least just from this corps, and we will give you a brass band to lead the procession!"

"Fine.  Now, Mr. Ock, I will have no difficulty in picking up sixty others from the various missions, gospel halls, and evangelical churches of the city; and if you will promise faithfully to bring two such exhibits as I have described, I will come marching in at the head of such a procession, with the band playing 'Onward, Christian Soldiers,' and I will be ready for the debate." 

Apparently the man who had made the challenge must have had some sense of humor, for he smiled wryly and waved his hand in a deprecating kind of way as if to say, "Nothing doing!" and then edged out of the crowd while the bystanders clapped for Dr. Ironside and the others." 

Christ changes lives. 

Can you honestly say that you have never observed any examples of the genuine transformation that can come about in a person as a result of his hearing and responding to the Christian gospel?  I doubt it.
