I have read this book several times over the past 20 years. It is a wonderfully paced book that brings a person to see their need for the fullness of the Holy Spirit, and the obstacles that may obstruct a person from experiencing this fullness. It is refreshing and sound in doctrine, unlike many of the contemporary books on the same subject. This is not a "light read", this book is for those who are mature in the faith, have a good grasp of the Bible, and simply realize their need for more of Jesus Christ in their lives. It is not for the person who does not bother reading the Bible. The foundation needs to be solid first. I highly recommend this book to anyone who finds themselves in that category...full of the Word of God, and hungry for more of Him operating in their lives.
