Before God granted me faith I was out of town in Prescott for a wedding. At this time I had 4 herniations in my spine that caused pain 24/7. I was in tears while walking aorund town with my wife so we got an uber to go back to our airbnb. Our driver had the Christian radio on at the time. I identified as a Christian, yet my faith was willed by myself. It was fake, with self righteous works to assure me. Anyways, I asked the man who was driving us if he was a Christian and he said yes. I went on to explain about the pain I was in, because he could tell something was wrong. He asked if he could pray over me, put some annoiting oil on me and then heal me. I was desperate for any kind of help so I said yes. He said he had the gift of healing. Well he put the oil on my face and some other areas(I forget) and prayed, and then asked me how I felt. I told him I felt the same. He asked if he could try again, so I was like ok. He did the same exact thing again and asked, how do you feel? Same.
I do not doubt that God can use his creation in order to bring about what He wants, I just have not ever seen it happen or hear about it.
