This was probably the most incredible healing that I witnessed during our YPI trip. It was one of the first nights we were with Global (forget which night, I am writing my testimonies post-trip), and we were in healing prayer.
I saw a blind man from the stage that the Lord was ministering to. He had a walking stick and was clearly blind. Randy was explaining that just watching the testimonies of the healing of others can cause healing in us if we just attempt to see we are healed by Christ. You could tell this man's faith in what Randy was saying, because he was standing and his eyes were fluttering. It almost seemed as if we were going to watch the Lord heal the man without anyone praying for him.
I prayed for a man at the evening meeting who was blind in both eyes and deaf in one ear. His sight had been getting gradually worse over the last year or two until he could barely see. I tested his eyesight by holding up fingers. He could not see.
