Who is Jesus's “God”?
The Bible answers this for us.
“My God” who is He?
All texts from NWT unless noted otherwise.
To whom was Jesus calling to at:-
“About the ninth hour Jesus called out with a loud voice, saying: "Eli, Eli, la´ma sabachthni?" that is, "My God, my God, why have you forsaken me?"”
Which is literally rendered "this is the God of me, God of me."-'The NASB-NIV parallel N.T. in Gk. & Eng.' with Interlinear Translated by Alfred Marshall*
Who is Jesus referring to at:-
“Jesus said to her: “Stop clinging to me. For I have not yet ascended to the Father. But be on your way to my brothers and say to them, ‘I am ascending to my Father (Literal Gk. “Father of me”^) and YOUR Father and to my God (Literal Gk. “God of me”^) and YOUR God.’”
^'The NASB-NIV parallel N.T. in Gk. & Eng.' with Interlinear Translated by Alfred Marshall
“My poss[essive]. pron[oun]. (attrib.) 1 of or belonging to me. 2 affectionate, patronizing, etc. form of address (my dear boy). 3 in expressions of surprise (my God!; oh my!). 4 colloq. indicating a close relative etc. of the speaker (my Johnny's ill again). my Lady (or Lord) form of address to certain titled persons. [from *mine1] .”-Oxford Dictionary
“God n[oun]. 1 a (in many religions) superhuman being or spirit worshipped as having power over nature, human fortunes, etc. b image, idol, etc., symbolizing a god. 2 (God) (in Christian and other monotheistic religions) creator and ruler of the universe. 3 adored or greatly admired person. … .”-Oxford Dictionary
Jesus must have been calling to the Almighty, the Father, his God, see John 20:17, “my God”, (Lit. Gk. "God of me" 'The NASB-NIV parallel N.T. in Gk. & Eng.' with Interliner Translated by Alfred Marshall) quoting from Ps 22:1 where King David was, showing that God is somone other than himself. No, Jesus cannot be Almighty God if he plainly says in the above texts that he himself has a “God”!
We can also add to the above, the following words, where Jesus is speaking from an exulted heavenly postion:-
"‘The one that conquers—I* will make him a pillar in the temple of my God**, and he will by no means go out [from it] anymore, and I* will write upon him the name*** of my God** and the name of the city of my God**, the new Jerusalem which descends out of heaven from my God**, and that new name of mine. Let the one who has an ear hear what the spirit says to the congregations.’”
**Which in litrealy rendered "the God of me."-'The NASB-NIV parallel N.T. in Gk. & Eng.' With Interliner Translated by Alfred Marshall
So we can ask again, who is Jesus talking about, as it cannot be himself as he says:-
John 10:25 "Jesus answered them: “I told you, and yet you do not believe. The works that I am doing in my Father’s name, these bear witness about me."
So what is the Name of Jesus Father, the following shows:-
1 Chronicles 29:10-13 "Then David praised Jehovah before the eyes of all the congregation. David said: “May you be praised, O Jehovah the God of Israel our FATHER, throughout all eternity. 11 Yours, O Jehovah, are the greatness and the mightiness and the beauty and the splendor and the majesty, for everything in the heavens and on the earth is yours. Yours is the kingdom, O Jehovah. You are the One exalting yourself as head over all. 12 The riches and the glory are from you, and you rule over everything, and in your hand there are power and mightiness, and your hand is able to make great and to give strength to all. 13 And now, O our God, we thank you and praise your beautiful name.
The God of Jesus, as at Micah 5:2-4
“And thou, BethLehem Ephratah, Little to be among the chiefs of Judah! From thee to Me he cometh forth--to be ruler in Israel, And his comings forth are of old, From the days of antiquity. 3 Therefore he doth give them out till the time She who bringeth forth hath brought forth, And the remnant of his brethren return to the sons of Israel. 4 And he hath stood and delighted in the strength of Jehovah, In the excellency of the name of Jehovah HIS God, And they have remained, For now he is great unto the ends of earth.”-‘Young’s Literal Translation’
 Added to show who is spoken of.
26 He himself [Jesus] calls out to me [Jehovah], ‘You are my [Jesus’] Father, My [Jesus’] God and the Rock of my [Jesus’] salvation.’
27 Also, I myself [Jehovah] shall place him [Jesus] as firstborn, The most high of the kings of the earth.
28 To time indefinite I [Jehovah] shall preserve my loving-kindness toward him [Jesus], And my [Jehovah’s] covenant will be faithful to him [Jesus].
29 And I shall certainly set up his [David’s] seed forever And his [Jesus’] throne as the days of heaven.
The according to The Bible, the answer to the question; "Who is Jesus' God?" is, "Jehovah."
Ephesians 5:19, 20 "Speak to one another with psalms, praises to God, and spiritual songs, singing and accompanying yourselves with music in your hearts to Jehovah, 20 always giving thanks to our God and Father for everything in the name of our Lord Jesus Christ."
The K.J.V. shows Jesus' mission here on earth for it says at Psalm 83:18:-
"That men may know that thou, whose name alone is JEHOVAH, art the most high over all the earth."
Jesus let all men know who his God was: JEHOVAH.
