Jesus himself has a God, a higher power, whom he worships (Ps. 18:49; John 4:22-23), whom he fears (Isa. 11:1-5; Heb. 5:7) and to whom he prays (Matt. 26:53; Luke 6:12, 22:44; Heb. 7:25). Notice these Scriptures regarding Jesus and his God.
“He shall stand and feed in the strength of the Lord, in the majesty of the name of the Lord his God” (Micah 5:4).
“My God, my God, why hast thou forsaken me?” (Matt. 27:46).
“I ascend unto…my God, and your God” (John 20:17).
“Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort” (II Cor. 1:3 NASB).
“Blessed be the God and Father of our Lord Jesus Christ” (Eph. 1:3).
“That the God of our Lord Jesus Christ, the Father of glory may give unto you the spirit of wisdom and revelation in the knowledge of him” (Eph. 1:17).
“Blessed be the God and Father of our Lord Jesus Christ” (I Peter 1:3).
“Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name” (Rev. 3:12).
The person speaking in the verse above is the ascended Jesus, who had been in heaven with the Father for some sixty years when the book of Revelation was written, but he still refers to God as “my God” four times. It is for sure that Jesus cannot be the Supreme God, while he at the same time he has a God to whom he submits.
