AI & Christianity Expert: The Truth About Christianity (And Why Atheism Is Fading)

Why does it matter? Because the mathematician who debated Dawkins makes atheism look like the irrational leap

John Lennox has spent 70 years doing to his own faith what most believers never attempt — subjecting it to rigorous, public, adversarial scrutiny. Eighty-two years old, 70+ peer-reviewed mathematics papers, two celebrated debates with Richard Dawkins. His argument today is not that God feels right. It's that atheism, followed to its logical conclusion, eats itself alive.

• If your brain evolved from a mindless, unguided process, you have no rational grounds to trust any conclusion it produces — including the conclusion that atheism is true.
• AI worship groups exist right now. The human drive to bow before something omniscient didn't vanish in a secular age; it found a new object.
• The Christianity most skeptics reject — earn your way to heaven through good behavior — is the exact position Christianity itself calls its opposite.
• Hell, Lennox says, is not cruelty imposed on the unbelieving. It is God permanently honoring the preference of people who consistently refused Him.

Atheism claiming rationality destroys it

If your brain evolved from a mindless, unguided process, you cannot coherently trust its reasoning — including the reasoning that concludes atheism is true. Lennox puts the question to scientists directly: "If the computer you use every day — if you knew it was the end product of a random process — would you trust it?" Every single one he's asked has said no.

The argument isn't that atheists are bad people. It's that they're standing on a foundation that collapses the moment you examine it. "Atheism claiming rationality destroys it." This is his central objection to Richard Dawkins and the new atheist movement — not their conclusions, but the self-undermining logic beneath them.

He made the same point in a famous exchange with Peter Singer, the Princeton philosopher. Singer opened a debate by noting that people rarely leave the religion they were raised in — a standard strike against Christian apologists. When Lennox got the floor, he asked Singer: "Were your parents atheists?" They were. "Then you remained in the faith in which you were brought up." The audience erupted. One of the world's top philosophers, Lennox notes dryly, apparently hadn't registered that atheism is a belief system.

He watches the new atheist movement fading. Not because the questions have gone away, but because the incoherence has grown harder to ignore.

AI has acquired the attributes of God and people are already worshipping it

Worship groups for AI exist today. Not as a hypothetical trend to watch — as a present fact Lennox states without drama.

The mechanism is structural: "You have a system even now that has got some of the qualities we normally associate with God — it appears to be omniscient, you can ask it any question, it is omnipresent through the internet." When something simulates divine attributes closely enough, the human impulse to worship finds a new object.

The danger Lennox identifies isn't the impulse itself. It's what gets confused in the redirect. AI has no consciousness. It simulates intelligence without understanding anything in the way that word actually means. It doesn't experience, doesn't know, doesn't mean. "You are bowing down to something that in the end is idolatrous because it is less than God."

Steven observes that people already confide in AI the way they once confided in priests. Lennox doesn't dispute it. What he calls for is precision about what the object of that confession actually is — a machine made in the image of humans, carrying all the limitations that implies, simulating omniscience it does not possess. The temptation, he says, is entirely real. The object is entirely hollow.

The race to engineer superhuman intelligence is 5,000 years old — and has always ended the same way

Solving death. Merging humanity with machines. Engineering gods with a small G. Yuval Noah Harari calls these the 21st century's two agenda items. Lennox calls them humanity's oldest recorded catastrophe, now dressed in silicon.

"The drive for humans toward self-deification — you see it all through history. The ancient Babylonian emperors were regarded as gods. The Roman emperors started calling themselves gods." The technical apparatus changes. The refusal to accept human limits doesn't.

When people arrive with the transhumanist pitch, Lennox smiles. "I say, you're too late." Physical death, he argues, was already solved 20 centuries ago when God raised Christ from the dead. The biggest upload in human history has already been scheduled. What Silicon Valley is proposing is a pale imitation of a promise already made, and a repetition of what empires have always tried.

The inversion he savors most: transhumanism consists in humans reaching upward to become gods. Christianity is the exact opposite — a God who reached downward, became human, and offered the relationship that transhumanism can only simulate. One direction has always ended in collapse. The other, Lennox says, already happened.

The Christianity most people rejected has never existed

"Well, I do my best and I hope that God will be kind." Lennox hears this constantly. His verdict is swift: "That isn't Christianity. It's the exact opposite of Christianity. That's a merit-based religion."

Most religious systems operate on a scales-of-justice model — good deeds accumulate, bad deeds subtract, you present your record at judgment and hope the math works out. Christianity, Lennox argues, is a completely different structure. The relationship begins with acceptance before any performance, not conditional on it. He illustrates with an analogy: imagine meeting the woman you want to marry, handing her a cookbook, and explaining that if she follows those recipes faithfully enough for 40 years, you will accept her. Every audience he's told this to has laughed. Then he tells them: that is exactly how most people have been taught to think about God.

His own faith rests on something he didn't earn and couldn't. "The trust is based on what someone else has done — what Christ has done — not what I have done, and that's what's given me the power."

If that account is accurate, the intellectual case against Christianity — that it's an unfair cosmic scoreboard — has been aimed for centuries at a target that Christianity itself explicitly repudiates. The straw man burned a long time ago.

Five hundred years of left-brain reductionism left a civilization that understands how everything works and knows the meaning of nothing

"We now find ourselves in a world where we understand how almost everything works — but we know the meaning of nothing."

Lennox borrows this diagnosis from psychiatrist Iain McGilchrist, whose research on the brain's hemispheres anchors his reading of why the spiritual revival is happening now. The left hemisphere narrows and focuses — it masters mechanism, measurement, procedure. The right hemisphere contextualizes — it grasps meaning, beauty, relationship. McGilchrist's argument, which Lennox finds persuasive, is that Western civilization spent roughly five centuries over-investing in the left side, reducing everything to "nothing but physics and chemistry," and is now paying the cognitive bill. "People rightly feel it's too small a world to live in. They're looking to break out."

The result: a generation — and a growing number of intellectuals — taking religious questions seriously again. Not because they've abandoned reason, but because reductionism reached a dead end. "Step by step, he appears to be creating more room for God, because God makes sense of the space he feels is very necessary to fulfill."

The spiritual revival isn't regression. The right brain is reclaiming function it should never have surrendered, and what looks like a return to religion is actually a civilization rebalancing after centuries of lopsided development.

Hell is God permanently honoring the preference you kept choosing

A loving God condemning kind, unbelieving people to eternal torment — this is the objection that ends most conversations about Christianity. Lennox says it rests on a portrait of hell that Scripture doesn't draw.

Start with who Jesus actually warned about hell: religious bigots. Not struggling seekers, not honest doubters, not people who simply couldn't find their way. The distribution is telling.

Then there's the nature of the destination itself. Drawing on C.S. Lewis, Lennox defines it plainly: "Hell is absence of God, and it's chosen. If a person doesn't want God in their life, God will give them what they chose." Throughout the Gospels, Jesus healed, taught, offered — and when people told him to leave them alone, he left. He did not force his way in.

In a Russian security prison death row where Lennox once visited, he met a man who had killed 12 women and was awaiting execution. The man said, "I deserve to be here." Then his face broke into what Lennox describes as a ghastly smile. "I met Jesus here, and he forgave me." No merit. No accumulated virtue. A relationship offered at the last possible moment and received.

Hell is the same freedom exercised in the opposite direction — permanently. "You can choose not to have God, and God will honor that choice. And that is hell."

Faith works exactly like trusting a spouse — evidence accumulates, certainty follows commitment

Demanding certainty before you commit to anything is an epistemological standard that would prevent you from ever marrying, hiring, or trusting a colleague. Lennox says it's also the wrong framework for Christianity.

"I trust my wife. I've been married to her for 58 years this year. It's evidence-based trust. I don't trust her for no reason." That's the model. Evidence accumulates. You make a commitment on the basis of what you already know and take the next step forward. "I do not believe this is a process of taking a leap into the dark, but it's making a commitment on the basis of what you know already and taking a step further forward."

He also reclaims the word skeptic. In Greek, skeptomai means to observe from a distance — fine as a starting position, but fatal as a permanent one. "If you are ever going to get to know a person, you've got to begin to give up your distance."

Lennox has spent 70 years at close range: entering debates, making himself vulnerable to the counterarguments, reading the opposition at its strongest. The certainty that characterizes him now — the peace Steven notices as the conversation closes — is the product of that accumulation, not the precondition for it.

What you choose to worship will shape what you become

What runs beneath every argument Lennox makes is a single, unresolved civilizational question: will the society racing toward AGI be honest about its own anthropology? The arms race, the worship groups, the transhumanist agenda — all of them require an implicit answer to what humans actually are. A machine made in the image of humans offers a very different answer than a God who became one.

As Steven closes the conversation, he notes what he's observed across hundreds of interviews: the Christians carry a peace most of his guests are still searching for. The argument isn't only in the books.

The question being asked in every lab racing toward AGI — whether or not anyone in it has framed it this way — is the oldest question there is.
