Answer
The moral argument commences with the observation that all individuals acknowledge a moral code (recognizing that certain actions are right while others are wrong). Whenever debates arise regarding right and wrong, we refer to a higher law that we presume everyone acknowledges, adheres to, and cannot capriciously alter. Right and wrong suggest a superior standard or law, and a law necessitates a lawgiver. Since the Moral Law surpasses human nature, this universal law demands a universal lawgiver. Consequently, it is contended that this lawgiver is God.
In substantiating the moral argument, we notice that even the most secluded tribes, isolated from the rest of society, uphold a moral code akin to that of others. Although variations may exist in civil affairs, virtues such as courage and loyalty, as well as vices like greed and cowardice, are universally recognized. If humans were accountable for this code, it would vary as much as any other human invention. Moreover, it is not merely a reflection of human behavior—rarely do individuals fully adhere to their own moral standards. So, where do these notions of proper conduct originate? Romans 2:14-15 asserts that the moral law (or conscience) emanates from a supreme lawgiver beyond humanity. If this holds true, then we should anticipate the exact observations we have made. This lawgiver is God.
Conversely, atheism fails to offer a foundation for morality, hope, or purpose in life. While this alone does not disprove atheism, if the logical implications of a belief system do not justify what we inherently recognize as true, it should be dismissed. Without God, there would be no objective groundwork for morality, no life, and no rationale for living it. Nevertheless, all these elements do exist, as does God. Hence, the moral argument supporting the existence of God.
