Christian Apologist: The Truth About Christianity (And Why Atheism Is Fading)
"If the computer that you use every day, if you knew it was the end product of a random process, would you trust it? Every single scientist that I've asked that question to have said, no, I would not. So I say, you've got a problem, haven't you? Your atheism goes too far. It undermines the very rationality we need to do science."
Lennox presented a philosophical argument against atheism, contending that if human brains are merely the product of mindless, unguided evolutionary processes, there is no logical reason to trust them for rational thought or scientific inquiry. He argued this internal contradiction fatally undermines atheism's claim to rationality, as scientists would never trust a computer known to be randomly generated.

About this episode

In this wide-ranging conversation, host Steven Bartlett interviewed John Lennox, an 82-year-old Oxford mathematician who has published over 70 peer-reviewed papers and emerged as one of Christianity's leading apologists in debates against figures like Richard Dawkins and Peter Singer. The discussion centered on artificial intelligence, transhumanism, and the intersection of faith and rationality in an increasingly technological age. Lennox warned that the race toward artificial general intelligence represents a dangerous power grab that threatens human dignity and could enable unprecedented totalitarianism, pointing to China's social credit system as a preview. He argued that transhumanist figures like Yuval Noah Harari are reviving humanity's ancient impulse toward self-deification by attempting to solve death and engineer superhuman beings, and revealed that worship groups dedicated to AI already exist. Throughout, Lennox made the case that Christianity offers the only coherent foundation for human meaning and rationality, claiming atheism paradoxically undermines the very rationality it claims to champion. Bartlett, who identified as agnostic, pressed Lennox on difficult theological questions—why God allows suffering, whether non-Christians can reach heaven, and how to verify religious truth claims—leading to an unusually vulnerable exchange about doubt, evidence, and the nature of faith. Lennox recounted visiting Russian death row and meeting a murderer of 12 women who claimed Jesus forgave him, using this as evidence of Christianity's transformative power. The conversation explored consciousness, creativity, the limitations of AI compared to human experience, and whether technological unemployment might paradoxically return humanity to more meaningful, relational ways of living. Lennox emphasized that he views Christianity as evidence-based rather than blind faith, comparing it to trusting his wife of 58 years, and urged Bartlett to continue his open exploration of truth.
