The Logical Outcome of Materialism
If there is no God, what follows? This is not a rhetorical question but a philosophical one with profound implications. Atheism is not merely a denial of God's existence but the beginning of a worldview that, followed to its logical conclusions, leads to nihilism—the denial of objective meaning, purpose, and value in existence.
Many atheists resist this conclusion. They insist that life can be meaningful without God, that we can create our own purpose, that morality needs no divine foundation. But the most intellectually honest atheists—philosophers like Friedrich Nietzsche, Jean-Paul Sartre, and Albert Camus—have recognized that removing God removes the foundation for much that humans hold dear.
This lesson examines the logical implications of atheism, not the personal character of atheists. Many atheists are kind, moral, thoughtful people. The question is not whether atheists can be good people but whether their worldview provides a coherent foundation for the goodness they practice and the meaning they experience.
The Logic of Atheism
If Materialism Is True
Atheism typically entails materialism (or physicalism)—the view that only matter and energy exist. There is no soul, no spirit, no transcendent reality—only physical stuff governed by natural laws. Let us trace the implications:
The universe is accidental. If there is no Creator, the universe exists by chance—a cosmic accident with no intention behind it. It was not designed, planned, or purposed. It simply is.
Human beings are accidental. We are unplanned byproducts of blind evolutionary processes—"mud that got up and looked at itself," as someone put it. There was no intention for us to exist; we are fortunate arrangements of atoms that happened to become conscious.
Consciousness is merely chemistry. Our thoughts, feelings, loves, and hopes are nothing more than electrochemical processes in our brains. The experience of meaning is an illusion generated by neurons firing.
The universe doesn't care. An impersonal universe has no concern for human beings. It is indifferent to our suffering, our joys, our aspirations. We are alone in an uncaring cosmos.
Death is the end. When we die, we cease to exist—permanently. There is no afterlife, no judgment, no reunion. Everything we have done and loved disappears into nothingness.
The Nihilistic Conclusion
If these premises are true, what follows?
No objective meaning. If the universe has no purpose, and humans are accidents, then there is no inherent meaning to existence. Any "meaning" we perceive is a useful fiction we create to cope—but it has no reality outside our own heads.
No objective morality. If there is no God, there is no transcendent source of moral truth. Morality becomes merely human convention— useful social agreements that have no binding authority beyond what we choose to give them.
No ultimate justice. If death is the end, the wicked often prosper and the righteous often suffer—with no final reckoning. Hitler and his victims share the same fate: non-existence.
No ultimate hope. Eventually the sun will die, the universe will suffer heat death, and everything that ever existed will be gone as if it never was. Nothing we do ultimately matters.
"If the dead are not raised, 'Let us eat and drink, for tomorrow we die.'"
— 1 Corinthians 15:32Nietzsche's Honest Atheism
Friedrich Nietzsche (1844-1900) was perhaps the most honest atheist in Western history. Unlike many contemporary atheists who want to have atheism without its consequences, Nietzsche understood what the "death of God" truly meant:
"God is dead. God remains dead. And we have killed him. How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives: who will wipe this blood off us? What water is there for us to clean ourselves? What festivals of atonement, what sacred games shall we have to invent? Is not the greatness of this deed too great for us? Must we ourselves not become gods simply to appear worthy of it?"
Nietzsche did not celebrate the death of God with naive optimism. He recognized it as catastrophic—the removal of the foundation for Western civilization's values. Without God:
- Traditional morality loses its foundation and must be abandoned
- The "herd values" of Christianity (humility, compassion, equality) are exposed as weakness
- Humans must create their own values through sheer will
- Only the strong "Übermensch" can bear the weight of godlessness
Nietzsche predicted that the 20th century would be the bloodiest in history as humanity worked out the implications of God's death. He was right.
Nietzsche was not advocating nihilism but warning about it. He saw the coming crisis and tried to find a way through it with his concept of the Übermensch—the "superman" who creates meaning through will. But his solution was available only to the exceptional few. For ordinary humans, the death of God leads to despair.
Atheist Attempts to Escape Nihilism
Most contemporary atheists do not embrace nihilism. They try to maintain meaning, morality, and purpose while denying God. But do these attempts succeed?
"We Create Our Own Meaning"
The most common response is that we can create meaning for ourselves—choose what matters to us, pursue our own goals, find purpose in relationships and achievements.
The problem: Invented meaning is not real meaning. If I decide that collecting stamps gives my life meaning, that doesn't make stamp collecting objectively meaningful—it just means I've chosen to care about stamps. When I die, my stamp collection will matter to no one, and even my caring will cease to exist. "Creating meaning" is just a coping mechanism, not a solution to meaninglessness.
"Morality Is Evolutionary"
Some argue that morality evolved because cooperation benefited survival. Altruism, fairness, and empathy helped our ancestors pass on their genes, so we inherit these moral instincts.
The problem: Evolutionary explanations describe how moral feelings arose, not why we should follow them. If morality is just a survival instinct, why should I be moral when immorality benefits me? Evolution also gave us aggression, tribalism, and selfishness. Why privilege the "nice" instincts over the "nasty" ones?
"Secular Humanism Provides Values"
Secular humanism affirms human dignity, rights, and flourishing without appealing to God. It provides a moral framework based on reason and human welfare.
The problem: Why should I value humanity? If humans are just complex arrangements of atoms—cosmic accidents in an indifferent universe—why are they special? Secular humanism borrows its values (dignity, rights, equality) from the Christian tradition without the foundation that made those values coherent.
"This Life Is Enough"
Some argue that the brevity of life makes it more precious, not less. Since this is all we have, we should cherish it all the more.
The problem: This doesn't address the meaninglessness; it just reframes it positively. A brief life in a meaningless universe is still ultimately meaningless. "Cherishing" an existence that ends in nothingness and has no ultimate significance is a psychological strategy, not a philosophical answer.
Nihilism Is Unlivable
The strongest argument against nihilism is that no one actually lives as though it were true:
We Cannot Help Believing in Meaning
Even the most committed atheist lives as though their life matters, their choices have significance, and some things are genuinely good or evil. We cannot escape the sense that meaning is real—that love is more than chemistry, that justice matters, that cruelty is objectively wrong.
Nihilism Leads to Despair
Those who actually try to embrace nihilism—who truly internalize that nothing matters—tend toward depression, anxiety, and despair. The human soul was not made for meaninglessness. We wither without purpose.
Nihilism Removes Motivation
If nothing ultimately matters, why get out of bed? Why pursue goals? Why care about anything? Nihilism undermines the motivation for living. Those who remain active and engaged are not living consistently with their philosophy.
The inability to live consistently with nihilism suggests something is wrong with it. Our irrepressible sense of meaning might not be a delusion but a perception of reality—a clue that we were made for purpose by a purposeful Creator. The heart's protest against meaninglessness may be evidence of the truth.
The Gospel Response to Nihilism
Christianity offers what nihilism cannot: genuine meaning, purpose, and hope grounded in reality rather than wishful thinking.
Meaning Is Real
If God exists, meaning is not invented but discovered. We are not accidents but creations—made intentionally, with purpose, by a God who cares. Our sense that life matters is not a delusion but an accurate perception of reality.
Morality Has a Foundation
God's character provides the standard for moral truth. Good and evil are not human conventions but reflections of who God is. Our moral intuitions point to a moral Lawgiver.
Justice Will Be Done
The wrongs of this world will be addressed. Evil will not have the last word. There is a Judge who will set all things right. This hope sustains us when injustice seems to triumph.
Death Is Not the End
Resurrection changes everything. If Jesus rose from the dead, then death is not final, our choices have eternal significance, and hope is rational. "If Christ has not been raised... we are of all people most to be pitied" (1 Corinthians 15:17-19). But if He has been raised, we are of all people most blessed.
"For I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us."

- How would you explain to an atheist friend that their worldview logically leads to nihilism? What are the steps in this reasoning, and why do many atheists resist this conclusion?
- Nietzsche understood that the 'death of God' had catastrophic implications for meaning and morality. How has history borne out his predictions? What examples illustrate the consequences of practical atheism?
- The fact that no one can actually live as though nihilism is true suggests something is wrong with it. How might you use this 'existential argument' in conversations with skeptics? What does our irrepressible sense of meaning point to?
