There are few marvels of the universe that even begin to compare with the human body. The wizardry of man, the gimmicks, the gadgets, the glitter of it all fades away when contrasted to the functions of the body. The framework itself is, with over 200 bones, more durable than steel and every joint tightly enclosed, moving in a constant bath of oil at the same time, producing its own oil.
The average person develops 2,500 calories a day, which is enough to heat and boil 25 pots of coffee. Within the brain, there is a thermostat with its own nervous system. If part of the body gets too hot or too cold, signals are sent to the control center and blood vessels of the skin contract or are more enlarged to give off more or less heat. No air-conditioning system man has ever developed even comes close to the one God gave you.
The electrical system of the body is beyond imagination. The brain contains 10 millions nerve cells. Your eyes are connected to your brain by 300,000 separate and private 'telephone lines.'
The best mechanical hand ever developed is but a clumsy feeble effort compared to the hand God gave man. What mechanical hand paints a picture or plays the organ or performs a delicate surgical operation?
Your eye is the most expensive camera known to man. It comes with built-in adjustment and with an automatic system no other camera has ever known. Each eye contains a hundred million nerve cells, which work together perfectly to allow you to see close up and at a great distance in living color.
Your ears have a keyboard of 1,500 keys. The average piano has 88. The human ear is so sensitive, that in a completely sound-proof room, you can actually hear the blood flowing through your vessels.
The average heart pumps blood through a system of thousands of miles of blood vessels, while resting a sixteenth of every second. That totals up to about six hours a day or about 20 years during the normal lifespan that the heart rests.
The mind of man defies comparison. With ability to reason, to remember, to plan - with intellect and conscience, and emotions - it is where God himself can dwell. Consider God's masterpiece, the human body.
