Are there viable pathways from nature to God?Natural theology is making a comeback, stimulated as much by scientific advanceas by theological and philosophical reflection. Science is increasingly raising questionsthat transcend its capacity to answer-above all, the question of the existenceof God. So how can Christian theology relate to these new developments?In this landmark work, based on his 2009 Gifford lectures, Alister McGrathexamines the apparent "fine-tuning" of the universe and its significance fornatural theology. Exploring a wide range of physical and biological phenomenaand drawing on the latest research in biochemistry and evolutionary biology,McGrath outlines our twenty-first-century understanding of the natural worldand discusses this new understanding's implications for debates about the existenceof God.
