This book is a fantastic sequel to Experiencing God. It is very God centered in how to relate to the Holy Spirit through the model of Jesus. With every discipleship class, every member is convicted and personally brought back to God. It's very practical in it's pneumatology. For exegetical basis see Ken Berding's book "What are Spiritual Gifts?"
I now have in my library 5 "Blackaby books." This volume is a thoughtful, insightful work on usually the most neglected member of the Trinity--The Holy Spirit. I enthusiastically recommend this to all Christians seeking a deeper understanding of The Spirit.
