Here are a couple of blurbs:
"Dr. Beeke is well-known for his landmark work setting the record straight on the Puritan doctrine of assurance. Now he comes to our aid again with a superb treatment of the Puritans on adoption. I welcome his expert entry into this important field, and commend his keen insights and careful analysis to all who are interested in knowing 'what the Puritans really said' about adoption."
- Ligon Duncan
"In this short but spiritually substantive book, Dr. Beeke - a wise and careful 'pastor theologian' in the best sense of both words - introduces us to the Puritans' comforting and transforming work on spiritual adoption. More than just historically informative, this volume should be warmly welcomed by all Christians who want to learn more about this crucial aspect of our identity as sons of God and joint-heirs with Christ."
- Justin Taylor
As you can see, I warmly recommend the book.
