This is a quote from Russell M. Nelson, the heart surgeon who invented the Heart-Lung machine. I was the beneficiary of it twice.

“Each organ of your body is a wondrous gift from God. Each eye has an autofocusing lens. Nerves and muscles control two eyes to make a single three-dimensional image. The eyes are connected to the brain, which records the sights seen.

Your heart is an incredible pump. It has four delicate valves that control the direction of blood flow. These valves open and close more than 100,000 times a day—36 million times a year. Yet, unless altered by disease, they are able to withstand such stress almost indefinitely.

Think of the body’s defense system. To protect it from harm, it perceives pain. In response to infection, it generates antibodies. The skin provides protection. It warns against injury that excessive heat or cold might cause.

The body renews its own outdated cells and regulates the levels of its own vital ingredients. The body heals its cuts, bruises, and broken bones. Its capacity for reproduction is another sacred gift from God.

Be we reminded that a perfect body is not required to achieve one’s divine destiny. In fact, some of the sweetest spirits are housed in frail or imperfect bodies. Great spiritual strength is often developed by people with physical challenges, precisely because they are so challenged.

Anyone who studies the workings of the human body has surely “seen God moving in his majesty and power.” Because the body is governed by divine law, any healing comes by obedience to the law upon which that blessing is predicated.

Yet some people erroneously think that these marvelous physical attributes happened by chance or resulted from a big bang somewhere. Ask yourself, “Could an explosion in a printing shop produce a dictionary?” The likelihood is most remote. But if so, it could never heal its own torn pages or reproduce its own newer editions!”
