This book is a useful introduction to Dunn's research, along with many important fields of NT studies. Since Dunn has been one of the key players in NT studies over the last several decades, any student of the Bible would benefit from reading this book, if only to be caught up on the major conversations. Moreover, for students who are methodologically and theologically savvy, it could be a great help. While many of Dunn's emphases and method can be frustrating at times, one cannot deny the impact he has made on the field, and this short book is an excellent summary of his research to date.
