God in His essential being is invisible (John 1:18, I Timothy 1:17), unknowable (Luke 10:22, Matthew 11:27), immaterial (John 4:24), omnipresent (Psalm 139:7-12), is one in number and unity (Deuteronomy 6:4), is Father of the universe as Creator / Progenitor (Isaiah 63:16, 9:6, Psalm 89:26), and Paternally to humanity as Nurturer and Caregiver (Psalm 103:13, Matthew 9:6).
The Word is God self-revealing (John.1:1-3), God’s self-disclosure of Himself (Hebrew1:1-3, Isaiah 9:6), God going out from Himself (Revelation 5:6,7) God proceeding or emanating; the one whose “goings forth” have been from of old, from everlasting (Micah 5:2 Revelation 1:8).
Jesus Christ is the Word become flesh (John 1: 1, 14 Micah 5:2), God manifest in the flesh (I Timothy 3:16), the image of the invisible God (Colossians 1:15), and in Him dwelleth all the fullness of the Godhead bodily (Colossians 2:9). He is God visible (Hebrews 1:1-3), knowable (John 14:8), approachable (Matthew 11:28-30), touchable (I John. 1:1-3, John. 20:27), is the revealer of the Father (John 14:9, 17:6), the only way to the Father (Matthew 11:27, John 14:6-8), and the Father revealed (John 10:30, Isaiah.9:6, Revelation 1:8, 11). He is the Alpha and Omega, the beginning and the ending, the Almighty, which was, and is, and is to come (Revelation 1:8). He is also completely human (Hebrews 2:10-18), the true son of Mary (Matthew 2:1, Luke 2:33, 34, Galatians 4:4), the second man Adam (I Corinthians 15:47), the last Adam (I Corinthians 15:45), and the Son of God by both birth (Luke 1:35, Rom. 1:3), and declaration (Romans 1:4, Acts 13:33). His victory over death, hell, and the grave (I Corinthians 15:1-4) elevates the name of Jesus to the position of highest universal authority. The full power and authority of the Godhead is encapsulated in that name (John 5:43, Philippians 2:9, John 14:13, 14, 26, Acts 4:12).
The Holy Spirit is God indwelling the believer in personal agency, (Jeremiah 31:31-33, Romans 8:9), is one Spirit (I Corinthians 12:13), is the Spirit of Grace (Hebrews 10:29), is the Spirit of God (Romans 8:9), is the Spirit of Jesus (John 14:17, 18, Acts 16:7, II Corinthians 3:17), is the source of and medium for dispensing God’s grace in the Church Age (Acts 2:38, I Corinthians 12:l), and is essential for salvation (Acts 2:36-38, 11:14, Romans 8:9).
