Devil Out of Newel Knight

“The meetings were well attended, and many began to pray vocally to Almighty God, that he would give them wisdom to understand the truth. Among those who attended our meetings regularly, was Newel Knight, son of Joseph Knight. He and I had many serious conversations on the important subject of man's eternal salvation; we had got into the habit of praying much at our meetings and Newel had said he would try and take up his cross, and pray vocally during meeting; but when we again met together he rather excused himself. I said, it is your duty; you must do it. He replied, I will tomorrow. He afterwards came to me and begged me to pray for him, saying he was greatly troubled in his mind, and could not pray; he wanted me to pray for him. I told him I would, but he must not neglect to pray for himself. He went into the woods, where he prayed vocally; for it was considered improper to pray vocally in the family circle, as there were those present who did not believe, and were opposed to it. After he had been away some time, he returned in a state of great distress of mind, and his body was acted upon in a very strange and unnatural manner. His visage and limbs were distorted and twisted in every shape possible, and finally he was caught up off the floor of the apartment, and tossed about most fearfully. His situation was soon made known to his neighbors and relatives. We called on the Lord in mighty prayer, and through our faith in the name of Jesus Christ, I cast the devil out of him, and he was immediately relieved of his pain, and was restored to his usual state of health and happiness. Many people witnessed this scene, and were convinced that the power of God was manifested, and that the devil had been cast out of him. He was immediately baptized by me, and became a member of the church.”
