After the Lord Jesus Christ left for Heaven, He sent the Holy Spirit to us to help, empower, protect, and guide us in the work that the Lord has committed into our hands the preaching of the Gospel to every creature, and the making of Disciples of all nations, teaching them to observe His Commandments. You will learn Who the Holy Spirit is, His Character, Ability, and Purpose, His Work in the lives of Believers and unbelievers, and His Ministry in this earth."
