Jedediah M. Grant — Devils Yielded Only to Consecrated Oil

The speaker recounts observing instances where Elders were unable to cast out evil spirits or heal the sick through fasting, prayer, and the laying on of hands alone, but when they subsequently used consecrated oil as commanded, the healings and deliverances occurred immediately.

Fuller account of this event (in the witness’s own words):

I have seen the Elders try to cast out devils, and to accomplish it they have fasted, and prayed, and laid on hands, and rebuked the devil, but he would not go out. I have then seen them bring consecrated oil, and anoint the person possessed of the devil, and the devil went out forthwith. That taught me a good lesson—that God Almighty, when He speaks, means what He says; and if a man's works are right, his faith will be right; and if his faith is wrong, his works are wrong. When a man whose faith is right goes forth to administer to the sick, he will anoint with oil, as well as lay on his hands and pray.
