Man is the crown of God’ s creation. Greater and more wonderful than the stars in the universe is the wonder of man himself. Look at our bodies first of all and see how wonderfully God has
created them.
Doctors tell us that the human brain has 30 billion nerve-cells, each operating at a potential of nearly one-tenth of a volt of electricity. Those over 35 years of age lose 1000 of these nerve cells every day - and these cells are never replaced. Yet the main functions of the brain carry on till the end of life - even though there is a slight loss in the sensitivity of the five senses.
Did you know, that each of our eyes has 130 million little rods for black and white vision and 7 million cones for colour vision? These are connected to the brain by 300,000 nerve fibres. The human eye can receive 1.5 million messages simultaneously! To duplicate the function of one eye, mechanically, it would require 250,000 television transmitters and receivers!
Consider the ear! The auditory nerve is only three-fourths of an inch long and has the diameter of an ordinary pencil-lead. But it has 30,000 electrical circuits within it. If we were to compare the human ear with a piano, whereas the piano key-board has 88 keys, the key-board of our inner ear has about 1100 within the same frequency range. In other words, it is so sensitive, that it can pick up 12 different tones between any two keys on the piano.
Now look at the heart and the blood-vessels. We don’ t usually think of them until they give us some trouble! But that heart which God has put within our bodies beats 40 million times every year, without any lubrication and without taking a vacation. Even though you didn’ t realize it, your heart beat within your body 100,000 times yesterday, pumping blood through 100,000 kilometers of blood-vessels from your head to your feet. Your body also produced more than 172 billion red blood-cells just yesterday to replace the damaged and worn out cells? Isn’ t it a miracle that you are alive today!
Consider the glands. The thyroid gland in our body requires only 1/5000th of a gram of iodine daily. Yet, if that microscopic amount had been lacking in you when you were a baby, you would certainly have been mentally retarded!
The pituitary gland is even more wonderful. Its daily output of hormones weighs only onemillionth of a gram. Yet even a slight increase of decrease in this output in a person, in his growing years, would make him physically and mentally abnormal! The reason we’ re healthy
today is because the intricate working of our body-mechanism has been so perfect.
