It is easy to make an argument for God's existence from a cosmological standpoint. As the years have gone by, a growing amount of scientific data has accumulated which negates atheistic assumptions about how matter and the cosmos came into existence and how it has arrived at its present condition. As a science teacher and public lecturer on the compatibility of belief in God and science, I have, been impressed with an increasing awareness on the part of many scientists and theologians that science and religion are symbiotic disciplines.
One question which inevitably comes up in a discussion of this nature is what is the origin of God? If God created matter/energy, and designed the systems that have propelled matter into its present arrangement, who or what accomplished that for God? Why is it any more reasonable to believe that God has always "been" than it is to say that matter has always "been"? As Carl Sagan has said, "If we say that God has always been, why not save a step and conclude that the universe has always been?" (Cosmos, p. 257).
From a purely scientific standpoint, it is easy to demonstrate that matter cannot be eternal in nature. The universe is expanding from what appears to be a beginning point in space/time, which appears to be a one time event. Hydrogen is the basic fuel of the cosmos, powering all stars and other energy sources in space. If the fuel of the universe has been used eternally, that fuel will eventually be depleted, but the evidence is that the cosmological gas gauge, while moving toward "empty," is yet a long way from being there'a condition incompatible with an eternal universe. The second law of thermodynamics insists that the cosmos is moving toward a condition of disorder, sometimes referred to as "heat death." Even in an oscillating universe, things ultimately run out of energy and "die." All of these evidences, and several others we have not made reference to, show that matter cannot be eternal, as Dr. Sagan and his associates would like to believe. However, this does not mean that we automatically accept the hypothesis that God is the Creator. Why is it not equally invalid to suggest that God has always been?
The problem here is that many people have a mistaken concept of God. If we conceive of God as physical, anthropomorphic (like man) being, the question of God's origin is valid. However, such a concept of God is alien to the Bible and to common sense. Consider the following descriptions of God from the Bible:
John 4: 24 - God is a Spirit:...
Matthew 16:17 - ...for flesh and blood hath not revealed it unto thee, but my father which is in heaven.
Numbers 23:19 - God is not a man, that He should...
Obviously, the descriptions and concepts of God given in these passages are that God is a spiritual entity. He exists outside of the three-dimensional, physical world in which we live.
The Bible further supports this concept of God in the following passages:
