This Bible Study Manual is the result of my notes. It is what I have taught every time a group wants to know more and be filled with the Holy Spirit. My goal is to present the serious student of the Bible to the Holy Spirit, the Third Person of the Trinity, the Comforter, and the Spirit of Truth, He who cries within us "Abba (Father )". We will answer questions like: Who is He? What is His work? How He does it? What is the baptism of the Holy Spirit? And what happens when it happens? I have added an appendix that describes the outpouring of the Holy Spirit in Guatemala, Central America.
