This is a wonderful book. I am somewhat biased in my appreciation for Dr. Horton since I had him as a professor in seminary. In spite of this, however, I think that this is one of the most helpeful books in regards to the New Perspective on Paul and Protestant, Reformed soteriology. His distinction between the Abrahamic and Sinaitic covenants is invaluable to contemporary exegesis. I also appreciate Horton's charitable tone which allows him to see certain valuable insights in New Perspective theologians while pointing out the extreme flaws in their assumptions and thinking. ( )
