Faith in God as Creator is reasonable because creation requires a creator. If one sees a lovely, well built house, he does not say, "I wonder how that house came into existence." He knows that the existence of the house means that someone built it. This is also true of our world. The fact that it exists requires that there must be one who built it. "For every house is builded by someone, but he that built all things is God" (Hebrews 3:4).
Faith in God as the Creator of all things is reasonable because life can only come from life! Everyone understands that that which is dead can not produce that which is alive. In Europe during the Middle Ages, people were very ignorant. They believed in "spontaneous generation," that is, that non-living things could give birth to living things. Louis Pasteur, a great French scientist in the 19th century, proved that spontaneous generation is false. Only life can produce life!
Let us make application to the world and the people in it. How did it come to be? There are only two possibilities. Either the world and all living things in it came from dead, non-living, non-thinking matter, or it came from mind, intelligence, life, therefore God. What do you think? Does a nest create a bird to sit in it, or does the bird, a living being, create the nest? Does a car make a man to drive it, or does the man who is living and intelligent create the car? It is totally unreasonable to believe that the earth which is filled with living plants, animals and persons was brought into being by dead matter. However, it is very reasonable to believe that a supreme, intelligent being, God, brought into existence the universe and the wonderful varieties of life which live in it.
It is also reasonable to believe in God as Creator because of the plan and purpose in the universe. The universe operates according to law. Scientists are busy discovering these laws which they use for man's benefit. The order and design of the laws point to a mastermind who originated them. It is not possible that our orderly universe happened by chance. For example, the earth is 93,000,000 miles from the sun. If the earth were closer, it would burn up. If it were farther away, the earth would freeze. Did this just happen by chance? Or, did a living Mind, God, design this?
Did the complex universe which operates in such orderly fashion, according to definite laws, just happen by chance? Or, is it the result of an intelligent God who created it? It would be more reasonable to assume that the telephone directory of Sydney, Australia, a city of 4,000,000 people, just happened by chance than to assume that the orderly universe came into existence by chance!
It is reasonable to believe that "in the beginning, God created the heavens and the earth" (Genesis 1:1). Only a powerful, highly intelligent God could have created the wonderful, complex world in which we live. Truly, "The fool hath said in his heart, there is no God" (Psalms 14:1).
