I realize that by Are book recomendations considered on topic? , this question will likely be closed. I only ask that you wait a few days to allow people to answer before closing (good information on the Holy Spirit tends to be classical rather than fad-ish.)
John 14:25 These things have I spoken unto you, being yet present with you. 26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. 27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
According to the trinity, God consists of: God the Father, God the Son, and God the Holy Spirit. Much has been written about the Father and the Son -- yet, there seems to be surprisingly little about the Holy Spirit. This seems somewhat unfortunate given that the Holy Spirit is sent to help and guide us.
We are told to pray to the Father, to study and be conformed to the image of Christ. What are we to do with the Holy Spirit? How do we interact with the Holy Spirit? What are classical resources written by well respected theologians on the dynamics + interaction with the Holy Spirit?
