Friedrich Nietzsche often insisted on the necessity of the existence of God for the existence of morality (though he then argued that neither truly existed). Nietzsche said,
“When one gives up the Christian faith, one pulls the right to Christian morality out from under one’s feet.”
Sartre, a philosopher born just a few years after Nietzsche’s death, agreed with Nietzsche’s assessment, but in contrast to Nietzsche’s relative optimism about the implications of a Godless society, Sartre found them disturbing and distressing. Sartre explains,
“The existentialist thinks it very distressing that God does not exist, because all possibility of finding values in a heaven of ideas disappears along with Him; there can no longer be a priori Good, since there is no infinite and perfect consciousness to think it. Nowhere is it written that the Good exists, that we must be honest, that we must not lie; because the fact is that we are on a plane where there are only men.”
Sartre believed with Nietzsche that if we take the God of the Bible out of the equation, then someone else must have formulated morality; and who is left but humans? The dilemma that Nietzsche, Sartre and others have continually arrived at is that if there is no God who has given us moral commands, there really is no morality at all.
The argument from morality asks, since we do see an objective moral law, what conclusion are we then left to make? The existence of a moral law points strongly toward the existence of a moral law giver. And, to use Humian language – this being, we call God. The specific identity of that God is up for further debate, but the moral argument credibly illustrates that the existence of a supreme moral being certainly is evident.
The moral argument provides strong support for the existence of an author of morality, of a being that has authority over and actively rules over all creation. Taken with the cosmological argument and the argument from design, this case for a Creator provides us with strong evidence that there is a perfect, necessary, and eternal being that created the universe with life in mind and has the authority to tell us how then we should live. This being, we call God.
Now the next step, is to find who that God is, and worship Him…
