As far as I can tell, of all the BBC talks that C.S. Lewis has given only one has survived: Beyond Personality, from 1944. It is one of Lewis’ thoughts about God and time, in this case about the idea of prayer.
“The point I want to drive home is that God has infinite attention, infinite leisure to spare for each one of us. He doesn’t have to take us in the line. You’re as much alone with Him as if you were the only thing He’d ever created”
The piece ends with a class Lewis conversation about whether we lose our personalty in Christ. What does it mean to be a “true person?”
His voice is startling to me–I think I still feel Anthony Hopkin’s voice is Lewis’. In any case, it is worth a listen.
