Jesus prayed to his Father and identifies his Father as the only true God:

Father.... this is eternal life, that they may know You, the Only True God and Jesus Christ whom You sent.

The Only True God, Jesus' Father, sent Jesus. In Mark chapter 12, there is an interesting exchange between the Jew Jesus and a Jewish scribe:

And one of the scribes came up and heard them disputing with one another, and seeing that he answered them well, asked him, "Which commandment is the first of all?" Jesus answered, "The first is, "Hear, O Israel: The Lord our God, the Lord is one; and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.' The second is this, "You shall love your neighbor as yourself.' There is no other commandment greater than these." And the scribe said to him, "You are right, Teacher; you have truly said that He is one, and there is no other but He; and to love him with all the heart, and with all the understanding, and with all the strength, and to love one's neighbor as oneself, is much more than all whole burnt offerings and sacrifices." And when Jesus saw that he answered wisely, he said to him, "You are not far from the kingdom of God." And after that no one dared to ask him any question.

Now let us stop for a moment and ask ourselves a very important question. Just who was this Jewish scribe talking about when he said, "HE is one" and "there is no other but HE"? Is it reasonable to suggest this scribe had a three person being in mind? Or is it more reasonable to suggest he had one person in mind?

[The Pharisees]: "We have one Father: God." (John 8:41).

The Jews never perceived God to be anything but one person. It would be ridiculous to claim this Jewish scribe had anyone but one person in mind. Jesus confirms this fact:

Jesus answered, "If I glorify myself, My glory is nothing; it is My Father who glorifies Me, of whom you say, "He is our God (John 8:54).

Jesus confirms that his Father was the God of the Jews. Jesus too was a Jew. Now notice how Jesus responds to the Jewish scribe.

And the scribe said to him, "You are right, Teacher; you have truly said that He is one, and there is no other but He; and to love him with all the heart, and with all the understanding, and with all the strength, and to love one's neighbor as oneself, is much more than all whole burnt offerings and sacrifices." And when Jesus saw that he answered wisely, he said to him, "You are not far from the kingdom of God."

Jesus wasn't a Trinitarian either. Both the Jewish scribe and Jesus the Jew had the same idea in mind when they said that God is one - Jesus' Father, one person.

Now it gets even more interesting. Notice how the Jesus said, "The Lord our God the Lord is one" and the Jewish scribe responsed to that statement by saying, "you have truly said that He is one, and there is no other but He." Clearly, the Jewish scribe is emphasizing the exclusivity of the God which they have in mind. He says that Jesus had just said "there is no other but He" indicating this is what the Shema is supposed to indicate. And Jesus confirms this fact by saying he had answered wisely. We find the same idea at Deuteronomy 4:35. We must ask, "there is no other but WHO exactly"? Who did Jesus and this Jewish Scribe have in mind exactly? The honest and reasonable person knows the answer.

Jesus' God was his Father and his Father alone. And it is for this reason that we find Jesus teaching his disciples:

"I am ascending to my Father and your Father, to my God and your God" (John 20:17).

The God of Abraham, Isaac, and Jacob was one person, Jesus' Father (Acts 3:13). Jesus' God was his Father. Our God is Jesus' Father. Jesus taught us the truth explicitly when he said, "my God and your God." Let us not serve a different God than Jesus.

Do you thus requite the Lord, you foolish and senseless people? Is not he your Father, who created you, who made you and established you?....See now that I, even I, am he, and there is no God besides ME (Deuteronomy 32:6.29).

Who is the one true God? How does this God portray Himself with respect to His identity? Does He portray Himself as a one person individual? How is he portrayed by others who are inspired by the Holy Spirit of God? Is this God a three person God or the one person Father of Israel and Jesus? What is this God's relationship to Jesus Christ and the Holy Spirit? Precisely who is YAHWEH God and who is not?

YHVH your God who goes before you will Himself fight on your behalf, just as He did for you in Egypt before your eyes, and in the wilderness where you saw how YHVH your God has borne you, just as a man bears his son, in all the way which you have gone until you came to this place.' (Deuteronomy 1:31).

To you it was shown, that you might know that YHVH is God and there is no other besides Him. (Deuteronomy 4:35).

Hear, O Israel: YHVH our God, YHVH is One. (Deuteronomy 6:4).

Do you thus repay YHVH, O foolish and unwise people? Is not He your Father who has bought you? (Deuteronomy 32:6).

[YHVH]: He will cry to Me, 'You are My Father, My God, and the Rock of my salvation.' (Psalm 89:26).

YHVH says to my Lord: "Sit at My right hand until I make Your enemies a footstool for Your feet." (Psalm 110:1).

[YHVH]:Behold, My Servant, whom I uphold; My Chosen One in whom My soul delights. I have put My Spirit upon him; he will bring forth justice to the nations. (Isaiah 42:1).

Behold, My Servant whom I have chosen, My beloved with whom My soul is well pleased. I will put My Spirit upon him, and he shall proclaim justice to the nations. (Matthew 12:18).

After being baptized, Jesus came up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him, and behold, a voice out of the heavens said, "This is My beloved Son, in whom I am well-pleased.(Matthew 3:16-17)

The Spirit of Lord YHVH is upon me. (Isaiah 61:1).

Have we not all One Father? Has not One God created us? (Malachi 2:10).

He will be great, and will be called the Son of the Most High.... And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God." (Luke 1:35).

For God so loved the world that He gave His only-begotten Son. (John 3:16).

But the hour is coming, and now is, when true worshipers will worship the Father in spirit and truth, for such the Father seeks to worship him. God is spirit, and those who worship Him must worship in Spirit and truth." (John 4:23-24).

Jesus returned to Galilee in the power of the Spirit. (Luke 4:14; cf. 4:1).

But if I cast out demons by the Spirit of God, then the kingdom of God has come upon you. (Matthew 12:28).

But beware of men, for they will hand you over to the courts and scourge you in their synagogues; and you will even be brought before governors and kings for My sake, as a testimony to them and to the Gentiles. But when they hand you over, do not worry about how or what you are to say; for it will be given you in that hour what you are to say. For it is not you who speak, but it is the Spirit of your Father who speaks in you. (Matthew 10:20).

Do not grieve the Holy Spirit of God. (Ephesians 4:30).

When they bring you before the synagogues and the rulers and the authorities, do not worry about how or what you are to speak in your defense, or what you are to say; for the Holy Spirit will teach you in that very hour what you ought to say. (Luke 12:11-12). If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him? (Luke 11:13).

You are the Christ, the Son of the Living God. (Matthew 16:17).

I know that you do not have the love of God in you. I have come in the name of My Father, and you do not receive me. If another comes in his own name, him you will receive. How can you believe, who receive glory from one another, and do not seek the glory that comes from the Only God? Do not think that I shall accuse you to the Father.(John 5:43-44).

Believe in God; believe also into me. In my the house of my Father are many rooms. If it were not so, would I have told you that I go to prepare a place for you? And when I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also. And you know the way where I am going." Thomas said to him, "Lord, we do not know where you are going; how can we know the way?" Jesus said to him, "I am the Way, and the Truth, and the Life; no one comes to the Father, but by me. (John 14:1).

Father.... that they know You the Only True God, and Jesus Christ whom You have sent. (John 17:3).

So also Christ did not exalt himself to be made a High Priest, but was appointed by Him who said to him, "You are My Son, today I have begotten you." As He says also in another place, "You are a Priest for ever, after the order of Melchizedek." In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to Him Who was able to save him from death, and he was heard for his godly fear. Although he was a Son, he learned obedience through what he suffered; and being made perfect he became the source of eternal salvation to all who obey him, being designated by God a High Priest after the order of Melchizedek. (Hebrews 5:5-10).
