Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
2 Corinthians 5:17
"In San Francisco, a man once challenged Dr. Harry Ironside to a 
debate on ‘Agnosticism19 versus Christianity’.
Dr Ironside agreed, on one condition: that the agnostic first provide evidence that agnosticism was beneficial enough to defend.
Dr. Ironside challenged the agnostic to bring one man who had been a ‘down-and-outer’ (a drunkard, criminal, or such) and one woman who had been trapped in a degraded life (such as prostitution), and show that both of these people had been rescued from their lives of degradation through embracing the philosophy of agnosticism.
Dr. Ironside undertook to bring 100 men and women to the debate who had been gloriously rescued through believing the Gospel the agnostic ridiculed. The skeptic withdrew his challenge to debate Dr. Ironside." CMI
