The holy spirit is not a person
By referring to God’s spirit as his “hands,” “fingers,” or “breath,” the Bible shows that the holy spirit is not a person. (Exodus 15:8, 10) A craftsman’s hands cannot function independent of his mind and body; likewise, God’s holy spirit operates only as he directs it. (Luke 11:13) The Bible also compares God’s spirit to water and associates it with such things as faith and knowledge. These comparisons all point to the impersonal nature of the holy spirit.—Isaiah 44:3; Acts 6:5; 2 Corinthians 6:6.
The Bible gives the names of Jehovah God and of his Son, Jesus Christ; yet, nowhere does it name the holy spirit. (Isaiah 42:8; Luke 1:31) When the Christian martyr Stephen was given a miraculous heavenly vision, he saw only two persons, not three. The Bible says: “He, being full of holy spirit, gazed into heaven and caught sight of God’s glory and of Jesus standing at God’s right hand.” (Acts 7:55) The holy spirit was God’s power in action, enabling Stephen to see the vision.
