I had a word of knowledge that God was healing kidneys. The first person that came to me had only 30% use of his kidneys from kidney disease. I prayed for him. He felt some relief, but only a blood test would prove complete healing.
Then, there was a young man I prayed for who had severe pain on the left side of his head. On the first attempt praying, he felt 70% relieved. After praying a second and third time, he was 100% healed.
