Thank you for making me so wonderfully complex! Your workmanship is marvelous—how well I know it.
~Psalm 139:14, NLT
“The world will not be destroyed by those who do evil, but by those who watch them without doing anything to stop them.”
I am not a doctor and so I am very limited in my understanding or ability to communicate the complexity of the human body. The human body is a chemical plant, more intricate and complex than any plant built by man. This plant changes the food we eat into living tissue. It causes the growth of flesh, blood, bones and teeth. It even repairs the body when parts are damaged by accident or disease. Power, for work and play, comes from the food we eat. Our body operates like a machine with some marvelous exceptions: the human body oils itself. It produces its own lubricants. There is no plant, no machine on earth that can be compared to the human body when it comes to complexity.
Your brain is the center of a complex computer system more wonderful than the greatest one ever built by man. The body’s computer system computes and sends throughout the body billions of bits of information, information that controls every action, right down to the flicker of an eyelid. In most computer systems, the information is carried by wires and electronic parts. In the body, nerves are the wires that carry the information back and forth from the central nervous system. I heard recently, that we have billions of nerves. In one human brain there is probably more wiring, more electrical circuitry, than in all the computer systems of the world put together. Yes, it is a marvelous thing—this brain of ours.
The human eye is also a truly amazing phenomenon. Although accounting for just one fourth-thousandth of an adult’s weight, it is the medium which processes some 80% of the information received by its owner from the outside world. The tiny retina contains about 130 million rod-shaped cells, which detect light intensity and transmit impulses to the visual cortex of the brain by means of some one million nerve fibers, while nearly six million cone-shaped cells do the same job, but respond specifically to color variation. The eyes can handle 500 messages simultaneously, and are kept clear by ducts producing just the right amount of fluid with which the lids clean both eyes simultaneously in one five-thousandth of a second.
Folks, I just gave you a couple of examples. Every system in our body is just as complex as the brain or the eye. Even the skeletal is complex. Charles Darwin was not totally convinced that his theory was correct. The thing that disturbed him most was the complexity of the human eye. What if he were living today with all the information we have. What would Darwin think about the DNA molecule or the atom.
