This book offers a compelling examination of the problem of evil and the doctrine of sin. It engages with and advances extant discussions on the topic by drawing together philosophical arguments, theological reflections, scientific evidence, Biblical exegesis, and real-life stories. The chapters provide a comprehensive evaluation of objections by anti-theodicists and atheists, and bring recent philosophical work concerning the arguments for Christian theism and advances in science and religion to bear on the discussion. The author defends the Cosmic Conflict Theodicy against philosophical and theological objections, and uses it together with the Connection Building Theodicy, Adamic Fall Theodicy, arguments for divine hiddenness, and Afterlife Theodicy to address the vexing problem of horrendous evil.
