He is not called "God" except in our English translations. In Hebrew he is called "elohim" and in Greek "theos". Both words can refer to beings other than Father Yahweh.
I don't know what you are trying to say here, but "God" cannot die. That is why, when the words elohim or theos are applied to the Son, it cannot be translated "God". "God" with a capital G should only be applied to the one true God, Yeshua's Father (John 17:3). All others should be translated "god" or "mighty one".
Two Gods? Impossible. How can one God have a God? There is no other God, but Father Yahweh. All others are lesser elohim as were the mighty men and judges of Israel.
Those who listen and learn from the Father go to the Son and HE will raise them up on the last day. That is Gods will. Jesus must then have all He needs to raise us up on the last day. All the fulness of God indwells Him.
The Father -The One True God, as Jesus stated, is the One who gave Jesus, (His Firstborn-as Paul wrote), HIS Fullness. The scripture truthfully depicts, (and cannot be broken), what the Father stated about His Son . The writer of Hebrews took pain to show this to future generations for understanding that the name Jesus inherited is far above even the angels of God. About the Son...when the firstborn comes into the world...
Jesus is the image of the invisible God and the exact representation of Gods being. ALL the treasures of wisdom and knowledge are hidden in Him. Yes -Mighty God in that context. No-He is not God as He is and always has been Gods Son. And as hebrews also states the creation was made through Him.
Hebrews:
For to which of the angels did God ever say,
“You are my Son;
today I have become your Father”
a ?
Or again,
“I will be his Father,
and he will be my Son”
b ?
6And again, when God brings his firstborn into the world, he says,
“Let all God’s angels worship him.”
c
7In speaking of the angels he says,
“He makes his angels spirits,
and his servants flames of fire.”
d
8But about the Son he says,
“Your throne, O God, will last for ever and ever;
a scepter of justice will be the scepter of your kingdom.
9You have loved righteousness and hated wickedness;
therefore God, your God, has set you above your companions
by anointing you with the oil of joy.”
e
10He also says,
“In the beginning, Lord, you laid the foundations of the earth,
and the heavens are the work of your hands.
11They will perish, but you remain;
they will all wear out like a garment.
12You will roll them up like a robe;
like a garment they will be changed.
But you remain the same,
and your years will never end.”
f
13To which of the angels did God ever say,
“Sit at my right hand
until I make your enemies
a footstool for your feet”
g ?
14Are not all angels ministering spirits sent to serve those who will inherit salvation?
