The Holy Spirit is the third person of the Trinity. He is completely God. He is called God (Acts 5:3-4), He has a will (1 Cor. 12:11), He speaks (Acts 8:29, 13:2), and He knows all things (John 14:17). He is not an "active force" as the Jehovah's Witnesses mistakenly teach. The Holy Spirit is alive and is fully and completely God. He is called the Spirit of God (Gen. 1:2), Holy Spirit (Psalm 51:11), the Helper (John 14:16, 26), and Eternal Spirit (Heb. 9:14). He knows all things (1 Cor. 2:10-11), He is all-powerful, (Luke 1:35), and He is everywhere (Psalm 139:7-13). (See Trinity and Holy Spirit).
