Book excerpt: How you spend your time and money controls what happens on this planet . . . Planet Earth and its people are in danger. We face ongoing economic and ecological crises. These will deepen unless all of God's people begin to act as one global community. Natural resources are diminishing and the economic world order is changing. We cannot go on living as though we can call up another planet. Change is needed now and this book addresses that. The biblical vision of the world as oikos, meaning household, is God's challenge to all people about the way we live now--and in the future. Oikos affirms the need for reconciliation and peace between faiths and nations and should determine our economic practices and how we care for the planet. In this timely and challenging book is a renewed call to follow the Maker's instructions. Whether it is 9/11, Chernobyl, or the 2008 financial crash, that call for change is repeating itself. This book not only explains why we need to change but also provides practical advocacy of how you can help to achieve it.
