My sister wrote this essay a few years ago, and shared it with me. A conversation brought it to mind recently, and I asked if she would permit me to post it here, which she did. Lisa is a practicing neuropsychologist, who specializes in helping people recover from brain trauma.
“But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people: that ye should shew forth the praises of him who hath called you out of darkness into his marvelous light” (1 Peter 2:9).
I love the story of Jesus healing the man who was blind from birth (John 9), because of its wonderful insights into the Savior’s perfect ability to love and heal us. John wrote, “Since the world began was it not heard that any man opened the eyes of one that was born blind” (John 9:32). John was trying to call our attention to the distinctiveness of this particular miracle. While wondering about why this event was different from Jesus’ other healings, I realized the reason stemmed from basic principles of neuroanatomy and brain function. We don’t really see with our eyes, we see with our brain. Our eyes are sensory organs that take in variations in light, and details from the world around us, then transform that information into electrical impulses. These electrical impulses are sent to some very specific areas in the back of the brain (the visual cortex & surrounding areas) that allow us to see and make sense of what we are seeing. While our eyes and the visual cortex of the brain are formed from birth for the very particular task of seeing, our vision and understanding of what we see develop as we interact with our environment. Vision is acquired in much the same way language is, in infancy and early childhood. For example, a young child learns names for visual details like colors and shapes, and eventually that a red, round shaped object might be an apple, or a pomegranate, or even a ball. But if a person is blind from birth, those parts of the brain which are supposed to do the work of “seeing” don’t develop in the same way, and can be encroached upon by other, working senses.
Applying this modern understanding of neuroanatomy, we can appreciate the complexity of Jesus’ miracle. It is more than just the man’s eyes that needed healing. If the Savior had only healed his eyes, the man would likely have been confused by the images he was “seeing” because his visual cortex wouldn’t have developed normally. He would have no frame of reference to understand depth or color or other visual details. In fact, there are modern examples of this very problem. But that is not what happened. The Savior anointed his eyes with clay and told him to “Go, wash in the pool of Siloam.” We are then told that the man went and washed “and came seeing” (John 9:7). The Savior did more than heal his eyes, he healed his brain. He made up for a lifetime’s lack of visual input – almost instantaneously. He restored, or completely repaired the man’s whole visual system.
Isn’t that a profound foreshadowing of later events? That through his atonement, Jesus can completely make up for our lifetimes of weakness and sin; and through his death and resurrection, he will restore our living physical bodies. He can and will make us whole again.
And yet another sweet bit of familiarity comes from this story… when the man was later asked by the Pharisees, repeatedly, about how this miracle could have occurred, the man defended Jesus and defended his works; “Why herein is a marvelous thing, that ye know not from whence he is, and yet he hath opened mine eyes…If this man were not of God, he could do nothing.” (John 9:30, 33). His genuine testimony resulted in him being cast out. But John was able to capture his words, “One thing I know, that, whereas I was blind, now I see.”
