In this deeply spiritual and warmly evangelical book, Dr. Torrey first carefully describes who the Holy Spirit is and how one can come to know Him as a person, just as real as Jesus Christ Himself, an ever-present, loving friend and mighty helper, who is always with us. Then he goes on to describe the work of the Spirit -- in the world and in the lives of Christians. His extensive study of the baptism with the Spirit is especially timely. Few people who read this book will come away without a new understanding of the Holy Spirit and a desire for the rich blessings one can realize through Him.
