Book excerpt: Theology matters! At last it can be understood easily, thanks to this “layman's language” approach to biblical belief. Authored by J. I. Packer, one of the premier theologians of Christianity, this summary of Christian teaching covers nearly 100 major Christian beliefs from a Reformed perspective. Brief, easy-to-understand chapters offer precise descriptions without sacrificing depth. Thoughtfully arranged and refreshingly readable, this is a book that belongs on the shelf of every Christian.
