Perhaps the most important contribution of this book is Peterson's retrieval of a strand of Christian theology that focuses on the human task to sustain, restore, and improve the conditions of our incomplete and damaged creation including humans as part of creation rather than to accept as God-given the state of the creation as we find it today. . . . Opens new terrain in bioethics for evangelical Christians. . . . One doesn't have to agree with every move Peterson makes here to recognize the great significance of this book for the current debate.
