John Lennox 2026: 'The New Testament Knows Nothing of Silent Christians'

At 81 years old, the Oxford mathematician who once debated Richard Dawkins on live television says the biggest obstacle to sharing your faith is not a lack of arguments. It is fear. In a wide-ranging interview with the Christian apologetics organisation Solas, Professor John Lennox told believers to stop waiting until they feel qualified — because, he said, "the New Testament knows nothing of silent Christians."

Lennox has been publicly defending Christianity since his student days at Cambridge in the 1960s. He has now spent six decades answering the hardest questions sceptics can throw at him, and his conclusion is disarmingly simple: evangelism is not reserved for preachers, theologians, or people with extensive biblical knowledge. It is for everyone.

"It was his conviction that Christianity is true that has motivated him to share the gospel" since those Cambridge days, the Solas interview with assistant director Dr Simon Wenham revealed. For Lennox, the Greek word "apologia" — from which we get "apologetics" — simply means "defence." And a defence, he insisted, is not about being erudite or answering philosophical questions. It is about "defending the truth of the Christian faith and clearing up objections and difficulties that people have with believing it."

Lennox knows the feeling that keeps most Christians quiet. He described believers who assume defending the faith is not their place — "a slightly distorted view," he called it — because they think apologetics belongs to intellectuals. His answer: nobody can take your experience away from you. "What we all can do is to share what Christ has done for us."

He recalled people coming to faith after watching his famous exchanges with prominent atheists like Richard Dawkins. But his point was not that everyone needs a debate stage. His point was that testimony — a lived story — does what arguments alone cannot. As he put it: "Winning an argument is one thing but winning the hearts of someone with whom you're speaking is an entirely different thing."

The professor's most practical advice may be his most freeing. "If you can't answer something people ask you, admit it immediately," he said. Rather than dodging a hard question, offer to look into it and meet again. He argued the effect "can be quite dramatic" — the other person learns that Christians are not know-it-alls, that their question is taken seriously enough to chase down an answer, "and that can be the beginning of a much deeper friendship and lead to people coming to faith in Christ."

John Lennox Interview: Faith Is a Person, Not a Theory

Lennox pointed to the workplace as a mission field hiding in plain sight — a place where Christians can model the faith and, he hopes, prompt people to start asking questions. He encouraged belivers to approach disagreements calmly, remembering that every person is made in God's image and deserves dignity regardless of their beliefs. "I think people can learn to respect you in that way," he said. "Take their questions seriously, take them seriously and see what happens."

He was clear that faith must arise from "personal conviction" rather than pressure or persuasion. There is no use browbeating anyone, he said — many people simply need more information before they can believe.

And at the heart of it all, Lennox drew a line he has drawn for sixty years: "We're communicating trust in a person, not in a theory. It's the idea that Christ is not only the truth, but the way and the life. And that He is the bridge between us and God and can bring us salvation."

Oxford Mathematician Christian: Why Lennox Still Speaks at 81

Reflecting on his life's work, Lennox said his two principle aims have been to make a reasoned explanation of Christianity accessible to the wider public — and to equip ordinary Christians to share their beliefs with greater confidence. He believes the mathematical order of nature itself "points towards God," and he has never separated his science from his faith.

His message lands at a moment when fear of speaking up is not abstract. A UK church is fighting in court for the right to preach on British streets after a council banned its amplified preaching — and church leaders warn that British churches invest almost nothing in evangelism. Lennox's answer to both is the same: ordinary believers, speaking honestly about what Christ has done for them, are the Church's real evangelism strategy.

The power of that simple testimony is written all over stories like the Saudi evangelist who lost 13 teeth for Jesus and never stopped speaking — and a 2026 study found two in three UK Christians are now evangelicals in a Church that is young, diverse, and growing. The raw material for a new wave of witness is already in the pews. It just needs to find its voice.

Lennox has spent a lifetime proving that faith and reason are not enemies. His final word to the fearful believer is almost a benediction: take their questions seriously, take them seriously, share what Christ has done for you — and watch what happens. The professor is 81. He is still speaking. The question he leaves behind is whether the rest of us, so much younger and so much more afraid, will finally open our mouths too.

But the most surprising part of this story is yet to come — keep reading.
