Please don't say it's a metaphor, because then the Bible as a factual book will be a fallacy, God could be a metaphor for life and living.
And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved.
John 1:18 and 1 John 4:12
No one has ever seen God, but God the One and Only, who is at the Father's side, has made him known.
No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us.
