Summary Point
Why is God the best explanation for the existence of morality?
Subpoints
Since morality is objective (independent of human preference) and applicable to all humankind, the source must transcend humankind – God.
-
If morality exists independent of humankind, then God exists.
-
If there are good reasons to believe that morality (a moral standard or right and wrong behavior) exists independent of humankind, there must be a source to make it applicable to them (humans have a moral compass). A personal God interested in the actions of people is the best explanation.
-
If God does not exist then there is no source to justify morality being objective, in other words, separate from humankind.
-
William Lane Craig provides a good distinction between objective and subjective.
-
“Objective means independent of human opinion. For example, the laws of nature hold whether we acknowledge them or not, so they are objective. Subjective means dependent on human opinion. For example, matters of taste, like whether coffee tastes good, are person-relative and so are subjective.”1

-
A moral standard (rules and values) exists independent of humankind.
-
Moral Actions: One way we know that a morality exists separate from humankind, is that certain actions are right or wrong independent of the opinion's of peopole.2
-
When people say an action is good or evil, they are referring to the action itself (the object), not simply how they feel about the action (which would make it subjective). Consequently, moral actions are objective, independent of humankind. This is most evident with extreme examples of evil:
-
Killing an innocent human being for no reason is clearly wrong (objective), regardless of whether some person or society says or does otherwise.
-
Virtually everyone says the Nazis were morally wrong for killing millions of Jews (objective). They don’t say this is wrong becuase it is their opinion and the Nazis were entitled to their opinion (subjective).
-
-
Moral Progress: Another way we know that morality is independent of humankind, is that there is a moral standard independent of society by which we judge each society. In other words, each society does not truly determine what is right or wrong behavior. There is no way for a society to make moral progress unless there is an standard outside of mankind to strive toward.3
-
Unless you believe this standard exist separate from society, how can you say slavery and the unfair treatment of women in U.S. history were wrong? Other Christian apologists make this point:
-
“…when we say “society is getting better” or “society is getting worse,” we are comparing society to some moral standard beyond ourselves.”3
-
According to C.S. Lewis, “The moment you say that one set of moral ideas can be better than another, you are, in fact, measuring them both by a standard, saying one of them conforms to that standard more nearly than the other.”4
-
-
Moral Values: Intuitively we know that there is a hierarchy of value in nature (e.g. humans are more valuable than animals, animals more valuable than plants, etc.). The only way to justify this hierarchy is to have an ultimate independent source of the highest value (God) to compare the rest of nature.5
-
-
Therefore, God exists.
-
Since morality is objective and applicable to all humankind, the source must transcend humankind. God is the best explanation. The standard of goodness as well as moral values are based on God’s character.
-
Humankind has a moral compass
​
-
This compass exists separate from humankind
-
It comes from God's perfect goodness
-
God has wired this compass into our mind (conscience).

Context:
-
What is morality? Simply put, it is rules for right and wrong behavior (duties). Based on these rules, we know what is valuable in nature (people more valuable than insects). Christian apologist, William Lane Craig provides helpful definitions:
-
Moral Duties: “refers to our obligation to act in a certain way, whether that action is right or wrong.”6
-
Moral Values: “refers to the worth of a person or action, whether it is good or bad.”6
-
-
Aside from the socio-path who lacks a conscience, everyone believes in morality. The question on the page is what is the source of morality, NOT how we come to know it. An atheist may argue that we don’t need God to be a moral person, but this misunderstands the question. The question at hand is not how we become aware of morality (parents, schools, etc.) but rather what is the best explanation for the existence of morality.
-
Different worldviews provide the following possibilities regarding the source of morality:
-
Theism: The source of morality is divine. God provides the rules for right & wrong behavior. This would make morality objective (actions themselves are right or wrong), not subjective (actions are right or wrong based on how you feel).
-
Atheism: The source of morality is mankind. Morality evolved based on social rules that mankind has agreed upon and/or they are characteristics hard-wired into our DNA. Either way the moral standard is up to mankind and can change.

Below is the logical syllogism that Josh and Sean McDowell offer regarding this argument:7
-
If objective moral values exist, God must exist.
-
Objective moral values exist.
-
Therefore, God must exist.
-
-
This argument for God's existence is supported by the following Bible verses:
-
So, when Gentiles, who do not have the law, instinctively do what the law demands, they are a law to themselves even though they do not have the law They show that the work of the law is written on their hearts. Their consciences testify in support of this, and their competing thoughts either accuse or excuse them (Romans 2:14-15 CSB emphasis added)
