The Unexpected Light is a book which seeks to inspire through the experience of science, history, and art, rather than theological rhetoric - reaching out to people not necessarily committed to the Christian faith but perhaps interested in it. The aim is to show how mercy is not just a doctrine, not just a teaching - although these are important things - but rather, a force integral to the future of human life on earth. Peter Fleming examines science, history, art - unified in faith. In a world which is imperfect by its very nature, mercy is a logical response to its people and to human behaviour.
