Francis Spufford is a prize-winning author who returned to faith as an adult after years as an atheist. His latest book is “Unapologetic: Why despite everything Christianity can still make surprising emotional sense”.

He says he didn’t write it to try to give an objective argument for Christianity, but to show why its concepts, doctrines and beliefs help those who believe it make emotional sense of the world.

He chats with renowned author Philip Pullman who is an atheist. They talk about new atheism, the atheist bus campaign, the concept of sin, the person of Jesus and more.
