I believe in divine healing. The testimonies from credible witnesses are simply too numerous to dismiss all of them out of hand. (Consider the compilation of modern day miracle testimonials found in the two volume work, Miracles: The Credibility of the New Testament Accounts, by Dr. Craig Keener of Asbury Theological Seminary.)
My father, Larry McCallister, Sr., experienced one powerful case during the 1962 Church of God state campmeeting then held at Cross Lanes, West Virginia. In those days they held a daily divine healing service at 5 P.M. during the campmeeting. A man from Clendenin, West Virginia learned of the service; he suffered with a broken back. The man called and said that he wanted to attend if he could raise the money to rent an ambulance. He was told to rent the ambulance and the bill would be paid. A group of ministers pooled their money for the trip.
Dad remembers that the man wore brown pajamas as he came wheeled in on a stretcher. Some of the ministers present were J. Ross Taylor, George Oiler* and Gene Curtis. Preachers prayed for him. Nothing visibly happened and the ministers left his side. However, during the second verse of Amazing Grace his hands were raised. During the third verse the man was walking up and down the aisles. The man rode home in the ambulance; he sat up in the front with the driver.
I believe in divine healing. I'm sure that man did, too.
*George Oiler, himself, knew God's healing. He was pronounced dead in the emergency room. A nurse was walking into his room to prepare his body for the funeral home when he sat up. She screamed, dropped water on the ground and ran from the room. Oiler reported that he felt himself rise out of his body; God spoke to him, telling him that he wasn't ready to leave and that he had to preach the straight truth. He felt himself lower back into his body. It should be noted that the nurse who screamed and ran came back into his room, knelt at his bed and gave her heart to God.
