My long road to become a doctor of medicine was only the beginning. After that came years of hospital work, research, specialty training, and certifying examinations. Then followed many years of teaching, service, and the challenges of the newly emerging field of open-heart surgery, all of which brought me to a profound reverence for the structure and function of the human body. I was convinced that its creation was divine
The Remarkable Human Body
Think of the genesis of a human body. It begins with the union of two reproductive cells—one from the mother and one from the father. Together, these cells contain all of the new individual’s hereditary information, stored in a space so small it cannot be seen by the naked eye. Twenty-three chromosomes from each parent unite in one new cell. These chromosomes contain thousands of genes which determine the physical characteristics of the unborn person. Approximately 22 days after these cells unite, a tiny heart begins to beat. At 26 days, blood begins to circulate. Cells multiply and divide. Some become eyes that see; others become ears that hear or fingers that feel the wondrous things about us.
Each organ is an amazing creation. The eye has a self-focusing lens. Nerves and muscles allow two eyes to make a single three-dimensional image. The ear converts sound waves into audible tones perceived in the brain.
The heart has four delicate valves that control the direction of blood flow. They open and close more than 100,000 times a day—36 million times a year. Unless altered by disease, they are able to withstand this stress almost indefinitely. No man-made material can be flexed so frequently and so long without breaking. Each day, the adult heart pumps enough fluid to fill a 2,000-gallon (7,570-L) tank. At the crest of the heart is a source of electricity that transmits energy down special lines, causing myriads of muscle fibers to work together.
Think of the body’s backup systems. Each paired organ has instant backup available from the other of the pair. Single organs, such as the brain, the heart, and the liver, are nourished by two routes of blood supply. This protects the organ if blood flow should be impeded through one of those routes.
Think of the body’s capacity to defend itself. To protect it from harm, the body perceives pain. In response to infection, it generates antibodies. They not only help to combat an immediate problem, but they persist to bolster resistance to any future infection.
Think how the body repairs itself. Broken bones mend and become strong again. Skin lacerations heal themselves. A leak in the circulation can seal itself. The body renews its own outdated cells.
The body regulates its own vital ingredients. Levels of essential elements and constituents are adjusted continuously. And regardless of wide fluctuations in temperature of the environment, the temperature of the body is carefully controlled within narrow bounds.
Through years of experience, I have learned that healing occurs only when all of the laws relevant to that blessing are obeyed.1 The structure and function of the body are governed by law. A verse of scripture so states: “Unto every kingdom is given a law; and unto every law there are certain bounds also and conditions
