The God of the Bible is revealed as one God. Both Old and New Testaments declare that there is but one God.
The oneness of the Godhead as revealed in Scripture

The Threeness of the Godhead as revealed in Scripture
Old Testament Scriptures
“In the beginning God…” Genesis 1:1-2 [The word for God is “Elohim” the plural form of the Hebrew word “El”.]
“Let US make man in Our image, according to Our likeness.” Genesis 1:26
And God (Elohim) said; ”Man is become as one of US, to know good and evil.” Genesis 3:22
“Come, let US go down and confuse their language.” Genesis 11:7
The Old Testament speaks of the Father;
“You, O LORD, are our Father.” Isaiah 63:16.
“Have we not all one Father.” Malachi 2:10
The Old Testament speaks of the Son;
“Kiss the Son lest He be angry.” Psalm 2:7,12.
“For unto us a Child is born, unto us a Son is given.” Isaiah 9:6
The Old Testament speaks of the Holy Spirit;
“The Spirit of God was hovering over the face of the waters.” Genesis 1:2
“But the Spirit of the LORD came upon Gideon.” Judges 6:34
New Testament Scriptures
The revelation of God as three persons is the distinctive ministry of the Son of God. One of the persons of the Godhead had to come to reveal God to man. It was the eternal Son, the Word, who was sent to declare God in His tri-unity of Being.
“No one knows the Son except the Father. Nor does anyone know the Father except the Son, and the one to whom the Son wills to reveal Him.” Matthew 11:27
“No one has seen God at any time. The only begotten Son who is in the bosom of the Father, He has declared Him.” John 1:18
The Incarnation was prophesied in the Old Testament and then fulfilled in the Virgin Birth of the Son of God. He was God manifest in the flesh.
“Behold, the virgin shall conceive and bear a Son, and you shall call His name Immanuel.” Isaiah 7:14
“And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.” John 1:14
The whole of the New Testament abounds with clear references to three distinct, divine persons, who are revealed as the Eternal Godhead.
Following is a set of Scriptures which show the distinction in the Godhead, as Father, Son and Holy Spirit. These verses tell of three persons, each having a distinct ministry and function, yet one in mind and will, working in harmony.
The Father’s voice spoke from heaven.
The Son of God in Jordan’s waters of baptism.
The Holy Spirit descending bodily in the form of a dove.
Believers were to be baptised into the name of
and of the Son
and of the Holy Spirit.
The Father hears the prayer of the Son.
The Son prays to the Father.
The Holy Spirit as the Comforter will be given.
1 Corinthians 12:4-6
Diversities of gifts, but the same Spirit (Holy Spirit).
Differences of ministrations but the same Lord (The Son).
Diversities of operations but the same God (The Father).
Access unto – The Father.
Through Him- The Son.
By one Spirit-The Holy Spirit.
There is one Lord – The Son.
There is one Spirit – The Holy Spirit.
There is one God – The Father.
2 Corinthians 13:14
The grace of our Lord Jesus Christ – The Son.
The love of God – The Father.
The communion of the Holy Spirit – The Spirit.
1 John 5:7-8
There are three that bear record in heaven:
The Word – The Son.
And the Holy Spirit,
And these three are one.
The Lord Jesus in John’s Gospel chapters 14-17 clearly brings to view the divine persons of the Godhead. The Son prays to the Father to send the Holy Spirit. He prays that the disciples may be “one as we are one” and that they may be “one in us” John 17:21-23. Here again is a compound unity, the unity of more than one person.

The Father is God, a distinct person. He is eternal, self-existent, invisible and immortal, dwelling in unapproachable light, whom no man can see in His fullness.
The Son is God, a distinct person, made visible by the Incarnation. The Son was pre-existent, that is, He existed before the world was. He is eternal along with the Father and the Holy Spirit. The Son is pre-eminent above all things except the Father. The Son is God manifest in the flesh.
The Holy Spirit.
The Holy Spirit is God, a distinct person. He is not an influence or a force but a divine person. He is eternal along with the Father and the Son.
