God as Nothing challenges the underlying assumption of both believers and atheists that their arguments depend on proof that God either exists or that God doesn’t exist. Gilbert Márkus demonstrates a long tradition in Jewish and Christian writings of viewing ‘God’ not as a particular entity, but as the mystery which underlies all that exists. This may develop into a way of talking about God which allows fruitful dialogue and – perhaps above all – a shared engagement in seeking ‘the things of God’: justice, peace and compassion.
