How would God have us respond to the brave new world of genetic engineering? In Changing Human Nature James Peterson offers an informed Christian defense of genetic intervention. Given that the material world and human beings are constantly changing, says Peterson, the question is not if there will be change but whether we will be conscious and conscientious about its direction. Part of our God-given calling, he maintains, is to positively shape our environment and ourselves, including our genes. While carefully addressing legitimate religious concerns, Petersons theologically grounded yet jargon-free discussion puts forth clear and specific guidelines for proper genetic intervention. Distinctive for its integrated, nuanced approach, Changing Human Nature will fill the need for a thoughtful, positive Christian perspective on this timely topic.
