The moral argument for God centers around the idea of objective morality. Objective morality is the idea that there are moral truths that exist independently of human opinion or cultural norms. These truths would be universally right or wrong, regardless of who or where you are. This objective morality necessitates the existence of God. There is a universal moral law, similar to physical laws, that governs right and wrong. This law needs a lawgiver, Who could be God. The following is the breakdown of the core reasoning of “moral argument”:

Premise 1: We have a widespread human experience of objective morality. Most people believe there are good and bad actions, and that some moral truths are held universally, for example, helping others in need is good, and cruelty or injustice towards anyone is wrong.

Premise 2: Objective morality requires a foundation or source for these moral truths. Morality would not exist if it were just based on personal opinions or cultural norms.

Conclusion: Therefore, there must be an objective source that grounds morality, and this source is the perfect Supreme God Who defines the rights and wrongs.

The moral argument for God is a complex debate with strong points on both sides. Here, I would like to quote the following passage from Chapter 4 of the book that I wrote under the heading of “Knowledge of right and wrong” for human beings:

There are certain mechanisms in place through which a human being can know what is good and what is bad. Firstly, the knowledge about the basic good and bad is programmed inside every human being by Allah SWT. According to the Holy Quran, “and by the soul, and the One who made it well, then inspired it with its (instincts of) evil and piety, success is really attained by him who purifies it, and failure is really suffered by him who pollutes it.” (Surah Shams, Ayats 7 to 10). Thus, we know that all people, from any part of the world belonging to any religion (including atheism), provided their nature is not perverted, know that certain deeds like speaking truth, helping the poor, respecting parents, feeding the hungry, and saving life are virtuous deeds. And deeds like speaking lies, killing innocent people, stealing, and cruelty are bad deeds. Despite having this knowledge, many people choose bad over good due to various reasons like seeking short-term gains, fulfilling personal desires, and gaining unlawful wealth. This inbuilt mechanism to know the basic good or bad is very powerful in human beings. Allah SWT has programmed a moral law inside every one of us to know the basic morals and ethics.  

Immanuel Kant, renowned German philosopher, and Enlightenment thinker, in his book “Critique of Practical Reason” wrote, “There are two things which fill the mind with ever new and increasing wonder and awe, the more often and the more intensely we contemplate them: the starry heavens above and the moral law within.”
