This is completely wrong and is nowhere taught in the Bible. Jesus is God; He does not have a God. Jesus was not created, and He did not have a subjective relationship with God. Jesus is “fully God and fully man.” While on Earth in a human body, he lived as a Jewish man under the Law, which required him to worship and relate to the Father as his God.
His submission to God was part of his “humiliation” or earthly mission (Philippians 2:5-11), not a reflection of his eternal nature. As we have discussed many times, well, it has been brought up several times, but you do not really discuss. John 1:1: Does not say the Word was “a god,” mainstream Bibles translate it as “the Word was God.” The Greek grammar describes the Word’s nature as divine.
John 20:28: Only 11 verses after the “my God” verse, Thomas sees the resurrected Jesus and exclaims, “My Lord and my God!” Jesus accepts this title without correcting him. Also, Hebrews 1:8: The Father himself addresses the Son, saying: “Your throne, O God, is forever and ever.”
However, as I said, you will probably ignore the facts and continue to believe the lie.
