Editor’s note: Adam Johnson has graciously allowed us to republish lecture, “The Moral Argument for God’s Existence.” Find the original post here.

The moral argument for God’s existence says that God exists because He is the best explanation for the fact that there are objective moral truths. Unlike the first-cause and design arguments, the moral argument is not based primarily on scientific evidence. Rather, it is based on the premise that objective morality is self-evident – we intuitively know that some things are right and others are wrong. Objective morality means that there are moral truths that exist beyond anybody’s own individual preferences, beliefs, or opinions. So, if morality is objectively real, what’s the best explanation for it? Where does it come from? Morality seems to be of a personal nature, and so it would make sense that morality comes from a personal source, but some atheist philosophers like Erik Wielenberg now argue that even though morality is objective, it doesn’t need a personal source. However, Adam believes that the description of God as a trinity in loving relationships provides the best explanation for the existence of objective morality.
