There are so many ways to summarize the moral argument for God’s existence that I have a hard time boiling it down to just one or two. The most concise summary of the deductive moral argument for God’s existence could be stated as follows: “If objective morality exists (and it does), then God exists.”

This summary is so concise, however, that it does little more than state the logic of the argument. Why think that only God can explain morality? Here is a concise summary that also attempts to explain the connection in a bit more detail: “If God didn’t exist, there would be no moral laws and no moral obligations. But all of us know that moral laws exist and that we have an obligation to obey those laws, so God must exist. Laws require law-givers and obligations require persons to be obligated to. God is the source of moral values and the One to whom we are obligated.”
