Summary: This sermon sets forth simple proofs that God is!
It is not unusual to be challenged today by someone who has either been brought up to disbelieve or has had bad experiences in life. They may ask the Christian to "prove to me there is a God!" Of course, "No one has seen God at any time" (John 1:18). Neither has anyone tasted, touched or smelled Him. Some in the Old Testament heard Him, but none of us has. We cannot isolate God in a test tube or examine Him under a microscope. We must use some other means to show God is.
The greatest evidence of God’s existence is found in His creation. "The heavens declare the glory of God; And the firmament shows His handiwork" (Psalm 19:1). Creation exhibits a design that must be the work of a designer. Most have no trouble understanding that any house, or other structure, had a designer, or architect, who drew up a plan for its construction. In the same way, the world around us displays a design that denies an origin of mere chance. Bert Thompson and Wayne Jackson, in their book A Study Course in Christian Evidences, on page 25, wrote,
Did you realize, for example, that the human body is composed of multiplied trillions of cells? In the nucelus [sic] of each cell, hundreds of thousands of genes are present. Each gene consists of a complex chemical called deoxyribonucleic acid (DNA). DNA has a complicated code for the mapping out of the entire development of the individual. If the coded instructions of a single human cell were put into English, "they would fill a 1,000 volume encyclopedia" (R. Platt, Reader’s Digest, October, 1962, p. 148).
One writer observed, "For every house is built by someone, but He who built all things is God" (Hebrews 3:4). The form and function of all the things God created teaches us there is a God (Job 12:7-10).
The cosmological argument seems to go hand in hand with the argument from design. This argument says the cosmos, including the world in which we live, obviously exists. It goes further to say that nothing comes from nothing. Therefore, there is a prime cause behind the cosmos, or God. The second law of thermodynamics, also known as entropy, says there is an ongoing flow from heat to cold, or what we might describe as a winding down process. Such an obvious process lets us know the universe is not eternal. Something had to be behind its existence.
Man’s moral nature tells us there must be a Moral Governor. People the world over condemned Adolph Hitler’s attempt to destroy the Jews. Why? Because man’s innate "sense of right" told them genocide was wrong. The animals do not display such a sense. Anyone who has ever seen a documentary on any of a number of animals has likely been impressed with their total lack of conscience. They can kill and eat another innocent creature without any pangs of conscience. For that reason, we do not bring an ox who gores a man up on charges of murder. Instead, we place the ox inside a fence and post warnings of the danger. In contrast, a man who kills is considered a criminal and will be tried for murder because he ought to know better. Thompson and Jackson ask, "If one does not acknowledge an eternal Mind with which intrinsic goodness is coexistent, how is ’morality’ to be explained?" (p. 28).
