Holy Spirit is mentioned 246 times in scripture, across 34 books of both testaments. First named in scripture around 4004 BC.
The third Person of the adorable Trinity.
His personality is proved (1) from the fact that the attributes of personality, as intelligence and volition, are ascribed to him (John 14:17, 26; 15:26; 1 Cor. 2:10, 11; 12:11). He reproves, helps, glorifies, intercedes (John 16:7-13; Rom. 8:26). (2) He executes the offices peculiar only to a person. The very nature of these offices involves personal distinction (Luke 12:12; Acts 5:32; 15:28; 16:6; 28:25; 1 Cor. 2:13; Heb. 2:4; 3:7; 2 Pet. 1:21).
His divinity is established (1) from the fact that the names of God are ascribed to him (Ex. 17:7; Ps. 95:7; comp. Heb. 3:7-11); and (2) that divine attributes are also ascribed to him, omnipresence (Ps. 139:7; Eph. 2:17, 18; 1 Cor. 12:13); omniscience (1 Cor. 2:10, 11); omnipotence (Luke 1:35; Rom. 8:11); eternity (Heb. 9:4). (3) Creation is ascribed to him (Gen. 1:2; Job 26:13; Ps. 104:30), and the working of miracles (Matt. 12:28; 1 Cor. 12:9-11). (4) Worship is required and ascribed to him (Isa. 6:3; Acts 28:25; Rom. 9:1; Rev. 1:4; Matt. 28:19).
