The Holy Ghost is the third part of the Trinity. He is God’s agent of action. “And the earth was without form and void; and darkness was upon the face of the deep, and the Spirit of God moved upon the face of the waters.” (Gen. 1:2) The Holy Spirit is Eternal, he was in the beginning and he is here now. In the beginning God worked through his Spirit in Creation. Today, his Holy Spirit creates hope and conviction in the hearts of would be Christians. (John 6:44)
