I have read through parts of the works of Owen and it is hard work. Intellectually rigorous is the word that comes to mind. I love Owen for the thoughts that he makes me think and this book has been a pleasure to read. Some of the redundancy has been removed for sake of clarity. At first I thought a real man would read the original works, but after 100 pages of this book I disagree. This is very helpful as to the ease of reading, a great stepping stone to reading Owen. Now to the content of this particular topic, Owen has amazing insights into the person and work of God the Holy Spirit. Buy this book you will not regret it!
