John Barnes's refutation of an heckler and preaching in Leeds

“I stepped forward to add my testimony, when immediately the Devil began to rage. One specimen of humanity with an ireful countenance, called loudly for a miracle, and said that Jesus performed cures without faith, and so did Peter. Finding an opportunity to speak, I replied that the Devil was the first individual who called for a sign, saying, “If thou be the Son of God, command that these stones be made bread.” The Scribes and Pharisees said, “Master, we would see a sign from thee. But he answered and said unto them, An evil and adulterous generation seeketh after a sign, and no sign shall be given them.” When Paul healed the cripple at Lystra, he perceived that the cripple had faith to be healed. I told them that we were sent to preach the Gospel, and not to perform miracles; that “these signs should follow them that believe;” that miracles were the effect of faith, and not faith the effect of miracles. The man was confounded, and had not a word to say. Shortly after, a young man came to me and requested baptism, saying he was convinced of the truth of what I had said.”
