Concept of God

What does “God” mean?  Is God a concrete thing like a chair or a human; or is it an abstract thing, like love or goodness?  Is there something that all concepts of God have in common, some feature that all cultures attribute to God?  Richard Swinburne, Emeritus Nolloth Professor of the Philosophy of the Christian Religion at the University of Oxford, joins John and Ken to explore the many ways in which people across the world conceive of the divine.
