Book excerpt: The third volume of Frame's Theology of Lordship series, this book focuses on biblical ethics. In an age of ethical relativism and suspicion of authority, how can we know what is good, virtuous, or just? Frame surveys non-Christian ethical traditions before setting forth a solidly Christian ethical method. By clarifying biblical norms, life situations, and personal dimensions, he presents a model for decision making that honors God in all aspects of life. Discussions range from natural law and conflict of duties to detailed explorations of the Ten Commandments in connection with questions surrounding worship, the Sabbath, church and state, respect for life and truth, sexuality, and the relation of Christ to culture.
