Q. “Don’t tell me about your religion. I don’t believe in God.” How would you answer that?
A. There are many ways to approach this. Let’s start by defining what, or who, we mean. The Oxford Dictionary defines god as “the creator and ruler of the universe and source of all moral authority; the supreme being”:
• Creator means “a person or thing that brings something into existence”;
• Ruler and source of all moral authority implies, as a minimum, intelligence and goodness; and
• Supreme being means the highest person.
For people who don’t believe in God, even though they may not say it, essentially they are denying:
• A creator or First Cause. The Law of Cause and Effect states that every material effect must have an adequate antecedent or simultaneous cause. If you trace our physical universe to its beginning, it must be caused by something or someone outside of itself. It cannot cause itself into existence, otherwise it would violate the law of non-contradiction. This is because the universe must exist in order for it to create anything, and it must not exist such that it has to be created. But self-creation requires both to be true simultaneously, and it simply can’t be, otherwise logic breaks down and there is no basis for reasoning. So a transcendent First Cause must pre-exist our universe, whom we call the Creator.
• A designer. If you examine our universe, you will observe order (e.g. planetary orbits), symmetry (e.g. structure in organisms), and intricate design such that things work together. Just as a building requires an architect and a painting requires a painter, so this careful design requires a highly intelligent Designer who planned and executed everything.
• A person. Not only is the First Cause all-powerful in order to create the universe, and all-knowing to design all living and inorganic matters, He must have personality as we have intellect, emotions, an innate sense of right and wrong (morals), and a will to decide, as that which is created, namely us, cannot be greater than the creator.
So simple logic tells us that an omnipotent (all-powerful), omniscient (all-knowing), moral being (person) exists, and we call this First Cause Designer God. To say that you don’t believe in God simply tells us that you do not want to accept the evidence, which are plenty. It does not change the fact that God exists, who you can know if you care to find out.
