In my humble opinion, everybody who dares call themselves evangelical, and this term is used widely today, should read this book and take its warnings and suggestions to heart. So many churches would call themselves evangelical today, but would not be able to give a proper definition for the term, or the history behind it. Read this book and you will get to see what it means to be evangelical!
Horton and others clearly delineate the dangers which face the Church of Jesus Christ, and if you're looking for fluff or easy reading, here, find another book like Max Lucado. This is meaty reading and worthy of the purchase. Highly recommended.
