In this book At Home in a Strange Land: Using the Old Testament in Christian Ethics, Andrew Sloane seeks to address this need. He outlines some of the problems that ordinary Christians face in reading the Old Testament as part of Christian Scripture and provides a framework for interpreting the Old Testament and using it in Christian ethics. He identifies some of the key biblical texts of both the Old Testament and the New Testament that both inform Christian ethics and challenge us to live as God's people. Using the paradigm of learning to travel in unfamiliar places, Sloane seeks to equip the reader with tools for understanding many of the puzzling and difficult passages found in the Old Testament. In sum, the book aims to "rehabilitate" the Old Testament for ordinary, even skeptical, 21st century Christians.
While many of the issues have been covered elsewhere, there is very little that seeks to bring together questions of interpretation and "ethical application" in one book aimed at lay people. The book would also be valuable in a college course on Christian ethics.
