I know right from child hood we have always see God been drawn on a story book, growing up we think that is exactly the image of God and that is what God looks like.
But that is not true God is, the image of God is something we can't even imagine as a human being, the bible said that he is like fire his image is glorious in which no man can , infact his image is magnificent, mortal body can't even carry the weight of his image.
So no man knows what the image of God looks like, in my own thought and opinion I think except angel's in heaven no other have seen God because he radiates with magnificieny.
The image of God is vast it has no ending, I believe on the last day we will all make it to see what his image really looks like.
