This is an in-depth study guide into the Holy Spirit, who is not a mere force. He is not energy. The Holy Spirit is a person and part of the Trinity along with the Father and the Son. God is Sovereign, and just so God wills and moves according to His will. Just so, the Spirit of the Lord moves and acts never out of His own accord, but always follows the leading of the Father. So the Spirit is interdependent, as there is a mutual dependency within the Trinity. The work of the Spirit is far greater in scope than merely the spiritual gifts, for the Spirit of the Lord leads us in our calling on the narrow path to the glory of the Lord. It is of utmost necessity for the Church to be one that is utterly and completely Spirit-filled, and not led by the flesh. For only in the Spirit can we fulfil the Great Commission, be true disciples and walk in His truth, way and life.
