Holy Scripture’s Holy Spirit! – Testing What Some Claim to be God’s Spirit Against What He Himself Says in His Written Word

Especially Hebrews 9:14 establishes the Spirit’s essence from all eternity past and unto all eternity future.   As the Westminster Confession of Faith observes:8 "The Lord Jesus, by His perfect obedience and sacrifice of Himself, which He through the eternal Spirit once [and for all] offered up unto God — hath fully satisfied the justice of His Father.   Hebrews 9:14."

2.   The Holy Spirit’s Personality     

Being God Himself, the Holy Ghost is not just a thing or an influence or a power.   To the contrary, He is a living Person.   Consequently, the Bible often uses personal pronouns and possessive adjectives (like "He" and "His") to refers to the Spirit.
