When God Talks Back: Understanding the American Evangelical Relationship with God
>A bold approach to understanding the American evangelical experience from an anthropological and psychological perspective by one of the country’s most prominent anthropologists.
>Through a series of intimate, illuminating interviews with various members of the Vineyard, an evangelical church with hundreds of congregations across the country, Tanya Luhrmann leaps into the heart of evangelical faith. Combined with scientific research that studies the effect that intensely practiced prayer can have on the mind, When God Talks Back examines how normal, sensible people — from college students to accountants to housewives, all functioning perfectly well within our society — can attest to having the signs and wonders of the supernatural become as quotidian and as ordinary as laundry. Astute, sensitive, and extraordinarily measured in its approach to the interface between science and religion, Luhrmann’s book is sure to generate as much conversation as it will praise.
You may have heard of it already, but there's a book about that (sorta).
