How many of you have heard of John of God and if you have what do you think about him?

When I went home yesterday Oprah Winfrey was on and I watched a program about John of God. He is a farmer and people are coming to him from all over the world to be healed. She had a Medical Doctor on the program that went and watched John help people and the Doctor’s life what changed. If you believe that John is healing people where do you think that comes from?
