That sounds like quite a cop out to me.
If God is not to be humanized, how does he even have a son or feel human emotions like love in the first place? Seems like you want to humanize God when it's convenient but not when it isn't.
God can know man, his knowledge of the human experience is complete now that he's been here in person in the shape of his son Jesus.
To use what I think is a little bit of a cliched explanation we all have the spark but Jesus had more of it than most of us. Anyway, God has knowledge of us, we dont exactly have knowledge of him and we've got to deal with a legacy of people projecting their own ideas onto the infinite, so at one time God is a man, another a woman, another the planet and matter, one time a king, another time a father.
Its a difficult error to avoid for some.
