The Bible makes NO mention of any “God the _____” who is distinct from “God the Father”.
I say believers are born of Yahweh God, and Yahweh God outside the universe is called God the Father.
Isaiah 42:5 LSB… Thus says the God, Yahweh,
Who created the heavens and stretched them out, Who spread out the earth and its offspring, Who gives breath to the people on it And spirit to those who walk in it,
Here is a summary of what I believe (similar to what Christians believed in the 2nd century)...
Yahweh God is solitary, created the universe alone.
Yahweh God is omnipresent inside and outside the universe.
Yahweh God inside the universe is called the Spirit of God.
Yahweh God outside the universe is called God the Father.
Yahweh God incarnate is called the Son of God.
