God the father spoke to the nation of Israel through the prophet Isaiah:
“You are my witnesses,” declares the Lord,
“and my servant whom I have chosen,
so that you may know and believe me
and understand that I am he.
Before me no god was formed,
nor will there be one after me.
11 I, even I, am the Lord,
and apart from me there is no savior.
12 I have revealed and saved and proclaimed—
I, and not some foreign god among you.
You are my witnesses,” declares the Lord, “that I am God.
13 Yes, and from ancient days I am he.
No one can deliver out of my hand.
When I act, who can reverse it?”
In the book of prophets like Isaiah, Jeremiah, Ezekeil, Zechariah etc.... God the father revealed himself to be the savior of all mankind. There is no other savior except he and he alone....
