If we are parts/members of the body of JESUS the MESSIAH and HE is the Head of Christian, we pray to the 'FATHER who art in Heaven', who is in fact JESUS's FATHER, who HE has shared us with and Helped us to become part of as co-heirs. We pray to the FATHER in JESUS's name.
Since the FATHER GOD is invisible, and so HE had to manifest in the flesh through the chosen servant of GOD for Israel, and finally through a perfect flesh of JESUS, who is submissive and obedience to GOD's Word and will always in physical manifestation representing, so that man can see and believe that GOD Himself is in our midst, as mankind perfectly and truly in GOD's image lived and spoke among mankind of this world to proclaim salvation from the wrath of GOD HIS FATHER in Heaven to come upon all sinners, 'who hates sin'. That is why the MESSIAH to come will be called as 'IMMANUEL', meaning GOD is with us'.
JESUS did not put Himself equal to GOD, for GOD is HIS FATHER. But GOD proclaim even to JESUS's disciples from 'a voice spoke from Heaven' that;
"This is My dearly beloved, who I AM well pleased."
"This is My only begotten, whom I AM well pleased. Listen to everything HE says."
No one can go to the FATHER, except unless through the SON of the FATHER, who was sent to make peace with all sinners, as 'God in the flesh' ministering to the people. That is why JESUS said;
"I AM the Way, the truth and the life, and no goes to the FATHER, unless by Me."
So, who GOD made God over us all?
The name and teachings of JESUS as Head to honor in the church of Christian and also JESUS as the Head to honor for Salvation, given through His Sacrifice on the Cross, for the remission of all sins, to all mankind to honor in thankfulness, in order to be accepted as sons and daughters into GOD's Kingdom, and further continue through Him and His Teachings according to the New Covenant.
