God, the Father, God, the Son, and God, the Holy Spirit are often referred to as the Trinity. Each are unique and individualistic and yet one. "The Holy Spirit is distinctly called God, and names are given to Him that properly belong to God (see Acts 5:3, 4; Isaiah 6:9; compare Acts 28:25; Jeremiah 31:31-34; Hebrews 10:15; II Corinthians 3:17, 19 in the Bible). Divine attributes, as knowledge, sovereignty, eternity are ascribed to the Holy Spirit (see I Corinthians 2:11; 12:11; Hebrews 9:14 in the Bible). Divine works, as creation and the new birth, are attributed to Him (Genesis 1:2; Job 26:13; John 3:3, 8). Worship and homage such as belong only to God are paid to the Holy Spirit (Isaiah 6:3-10; compare Acts 28:25-27; II Corinthians 13:14 in the Bible)."

Holy Spirit is "the immediate source of all life, physical and intellectual (see Psalm 104:29; Isaiah 32:14, 15; Job 32:8; 33:4; Genesis 2:7; Exodus 31:2; Numbers 11:17 in the Bible). He bore an important part in the coming of Christ in the flesh and the qualifying of His human nature for His work (see Luke 1:35; John 3:34; 1:32 in the Bible). He is the revealer of all divine truth. The Holy Scriptures are especially the product of the Holy Spirit (see Micah 3:8; John 14:26; 16:13; I Corinthians 2:10-13; II Timothy 3:16 in the Bible). He moves upon the hearts and consciences of all men, attending revealed truth with His power wherever it is known, and even where it is not known, affording some measure of divine light and gracious influence (see Acts 2:17; John 16:8-11; I Corinthians 2:4 in the Bible). He convicts men of sin, graciously aids them in repentance and faith; regenerates, comforts, and sanctifies believers; bears witness to their acceptance with God and adoption as God's children; dwells in them as the principle of a new and divine life.
