Holy Ghost: 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 Corinthians 2:10,11; 12:11). He reproves, helps, glorifies, intercedes (John 16:7-13; Romans 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 Corinthians 2:13; Hebrews 2:4; 3:7; 2 Peter 1:21).

1. from the fact that the names of God are ascribed to him (Exodus 17:7; Psalm 95:7; comp. Hebrews 3:7-11); and
2. that divine attributes are also ascribed to him, omnipresence (Psalm 139:7; Ephesians 2:17,18; 1 Corinthians 12:13); omniscience (1 Corinthians 2:10,11); omnipotence (Luke 1:35; Romans 8:11); eternity (Hebrews 9:4).
3. Creation is ascribed to him (Genesis 1:2; Job 26:13; Psalm 104:30), and the working of miracles (Matthew 12:28; 1 Corinthians 12:9-11).
4. Worship is required and ascribed to him (Isaiah 6:3; Acts 28:25; Romans 9:1; Revelation 1:4; Matthew 28:19).
