Person and Work of the Holy Spirit, as Revealed in the Scriptures and in Personal Experience [PDF ebook] 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It is of the highest importance from the standpoint of worship that we decide whether the Holy Spirit is a Divine Person, worthy to receive our adoration, our faith, our love, and our entire surrender to Himself, or whether it is simply an influence emanating from God or a power or an illumination that God imparts to us. If the Holy Spirit is a person, and a Divine Person, and we do not know Him as such, then we are robbing a Divine Being of the worship and the faith and the love and the surrender to Himself which are His due.
