Probing yet joyful, this examination demonstrates the centrality of God’s beauty in both faiths, presents the sacred arts of both religions, and explores the diverse ways in which devotees honor God. Candid and comprehensive, this discussion argues that Christian and Muslim artworks are not merely adornments, but the essential means of motivating adherents to live beautiful lives—lives devoted to the service of God and humanity.
