9:1-12 Seeing Is Believing Jesus demonstrated his power over sickness and disease. We are familiar with the healing power of Jesus, but this was something special. This was not healing a small cut. Rather, this was giving sight to one who had never seen before. Today, we know that this would involve restoring neural pathways in the brain. In Jesus’ day, such healings were unheard of (9:32). This was an amazing miracle, but it also resulted in spiritual vision—faith.
