For my adult Catholic trying to lead the Christ-life, it is useful to recall the reasons for believing. It is helpful to review why we know that God is exists. Is there a God? Is there a God above and beyond us all? Above our life and death, above our joys and sorrows, above our world and space program? For thinking people, this is really the important question. Is there a God? People have been asking this questions for as long as people have been thinking, but now so much more is known about this world and about us. There are answers and ideas never known before. The great think, Thomas Aquinas, lived in the 13th century. Not until the 17th century did man discover the microscope, cell structure, the circulation of the blood, etc. Much of what is known about the world has been learned in recent scientific studies. For me, the strongest reasons for believing in God are shown by the human body. Modern medical science says much about the remarkable design of that body – a design that in many thousands of ways advertises that the most careful, amazingly intelligent planning. In asking yourself whether there is a God, think about that design—for cleverer than the design of any automobile, a watch, and any piece of machinery. You own a body. Think – really think --- about it. Here are some reasons why your body is a product made by a most Intelligent Designer:
Your skull and brain
The human brain is the control center for the senses and nerves. It is the place for reasoning, memory, and decision-making. The skull protecting this brain is made of tough, hard bone. Light but strong, it is shaped into a design that makes architects and engineers admire its strength, scientists do not yet understand how a person remembers or thinks or feels. But they know the brain is an unbelievably complicated center of communications. The brain has 10 billion cells that never sleep, and these cells are linked with billions of inter-connectors. It is an electro-chemical network that runs the body. In some brain areas a hundred million cells fit into a cubic inch, and every one is connected to at least 60,000 others. It is an awesome mass, sophisticated, untiring, elaborately protected.
The way in which you see things-see the printed material—is because of incredible design. The back of the eye, or retina, is part of the brain itself. Your eyes are a camera, with the size of the pupil adjusting to light and the eyeball adjusting to distance, so that light rays focus on your retina. The retina has 125 million tiny rods and several million cones, so that your brain gets the picture, and in Technicolor. There are even chemical adjustments for night vision. The eye sees at one time several hundred million visual fragments, and the brain pieces them together and interprets them to see the important things.
The eyeball is bathed, behind and in front, by salt water that cleans it. The water is constantly being manufactured. The tear system is the admiration of any designer. There are glands to product tears, two drainpipes to carry excess water down to the nose, grease glands to protect the lower lids, and even a special chemical in the water to destroy bacteria. And all this is fitted into such a compact space.
Hear the sound waves enter the ear, and bitter wax inside the ear keeps insects away from the ear canal. The eardrum vibrates, and three tiny bones in the middle ear magnify this wave motion 22 times. A tube is to keep are pressure equal. The inner ear is a jewel of design, with an arrangement to soften the overly harsh sounds. The sound wave then travels to the great auditory never that has 25,000 fibers.
Whittaker Chambers regained his faith in God one day when watching his daughter at her breakfast. “My eye came to rest on the delicate convolutions of her ear—those intricate, perfect ears. The thought passed through my mind: … they could have been created only by immense...
