The Holy Spirit is the third Person in the TRINITY. He has the same power, the same glory with God the Father and God the Son. He is one with Father and the Son who is to be worshiped and served. Three Persons that become one are the source of blessings to all the living creatures in Heaven and on earth. The Holy Spirit has a great work to perform. He Teaches, He Speaks to us, and bears witness in us.
John 14:16-17
16 And I will pray the Father, and He will give you another [a]Helper, that He may abide with you forever— 17 the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.
