Book excerpt: Editors and authors James Estep and Jonathan Kim have pulled together something often talked about but seldom seen, namely, a thoroughgoing attempt to integrate theology and science, in this case, social science. Their organization, interpretation, and evaluation of mountains of information from both sides has resulted in an expert, yet easily understandable guide to Christian spiritual formation and development. Both academics and practitioners will find help in this volume, one that is certain to be a standard work for years to come.
