Let’s assume for a moment that God doesn’t exist, but we do. If God doesn’t exist, then the only explanation for the existence of life is evolution. And if evolution is how we came to be, then we are logically no more than very organized rocks and minerals—the dust and minerals left after the body dies and decays. And if we are nothing more than highly organized rocks, could there be such a thing as right and wrong, good and evil, or morality? Let’s think about it.

Rocks and what they do are completely without morality, amoral. If a rock does nothing for a million years, it’s inaction is neither good nor bad—it’s just following the laws of physics. And if a rock, perched on a hillside, rolls or falls down that hill crushing smaller rocks to smithereens along the way, it’s neither right nor wrong—it’s just a rock obeying the law of gravity. Meteors crashing into a planet are only atoms and molecules doing what atoms and molecules naturally do.

And if we are only highly organized rocks, then morality doesn’t exist for us either. Murder, theft, rape, cheating, lying, injustice, and violence lose their meaning, becoming only like gravity, chemical reaction, or fusion—without moral value, the “rock standard”.

But we all know better—pagans, philosophers, agnostics, atheists, and even children. We know that there’s an objective, world-wide standard of good and evil behavior—a right and a wrong. The apostle Paul put it this way, “For when Gentiles who do not have the Law do instinctively the things of the Law…they show the work of the Law written in their hearts, their conscience bearing witness…” (Romans 2:14, 15).

And it is this certainty of the existence of an objective moral code, that evidences God. Without Him there is no moral standard—just the “rock standard”. He is the origin of this standard that men everywhere recognize and live by. And He will hold us accountable.

With God, murder is heinous; without God, it is “meh”. With God, kindness, loyalty, and courage are valuable and good; without God, they are as insignificant as a meteor falling helplessly into the sun (who knows and who cares?). With God, good and bad have great meaning and value; without God, good and bad do not even exist.

Bottom line, the existence of God and the existence of morality are irrevocably and logically linked. To say that there is no God is to recognize no right and wrong. But to say that there is such a thing as morality is to also recognize that there is a God. To confess one is to confess the other; to deny one is to deny the other, as well.

Of course, there are many more layers and questions related to this proof than this brief article can address, nevertheless, the moral argument for God’s existence is a strong one and should be carefully considered by the honest seeker.
