50 Core Truths of the Christian Faith: A Guide to Understanding and Teaching Theology by Gregg R. Allison is a book that examines fifty church doctrines, guiding the reader on how to teach them. Some of my favorite lessons were the ones that focused on human nature, common grace, and baptism with the Holy Spirit. The text would be easy to use in a classroom setting; the end of each chapter even includes a teaching outline. The content is well-written, and I appreciate the book’s thoroughness and depth.  I like how each chapter talks about understanding the doctrine, enacting the doctrine, and teaching the doctrine.
