The growth of the Pentecostal churches since the early 1900's and the rapid rise of the charismatic movement since the 1960's have called the world's attention to the Holy Spirit. Exactly who, or what, is the Holy Spirit?

Some believe that the Spirit is a force, not a person. Others teach that the Spirit is a form in which God the Father deals with men.

Gordon H. Clark, one of the most respected and renowned Christian philosophers and theologians of the twentieth century, discusses the Holy Spirit in detail, collecting the Biblical information and arranging it into a logical and systematic presentation. He relies entirely on Scripture and not at all on experience in his presentation. The result is a clear, concise, and accurate statement of the nature of the Holy Spirit and his work in the world today.
