But it's clear that speaking of God as our Father is metaphorical. Indeed any language about God is non-literal.
Jesus doesn't give us a philosophical definition of God.
If he did, that would be the non-literal one.
He speaks about God's actions, and speaks of him as Father, which is basically speaking of personal relationship with him.
Wait....What?
But not literal actions and not a literal personal relationship?
18 I am One who testifies about Myself, and the Father
who sent Me also testifies about Me.”

“Where is Your Father?” they asked Him.“You do not
know Me or My Father, Jesus answered. “If you knew Me,
you would know My Father as well.”
John 8:55
You do not know Him, but I know Him. If I said I did
not know Him, I would be a liar like you. But I do
know Him, and I keep His word.
John 14:7
If you had known Me, you would know My Father as well.
From now on you do know Him and have seen Him."
John 14:9
Jesus replied, "Philip, I have been with you all this time,
and still you do not know Me?
Anyone who has seen Me has seen the Father.
How can you say, 'Show us the Father'?
John 15:21
But they will treat you like this on account of My name,
because they do not know the One who sent Me.
John 16:3
They will do these things because they have not
known the Father or Me.
1 John 2:23
No one who denies the Son can have the Father;
whoever confesses the Son has the Father as well.
King James Bible
Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and
to my God, and your God.
