John 1:18

No one has ever seen God, but God the One and Only, he who is at the Father’s side, has made him known.

God is a Spirit, that demands to be worshiped in Spirit and in truth. No one has seen God the Father. He does not permit idols. The Messiah came from Heaven to Earth, took on flesh, to make us understand who this Spirit is. Than He went back into the Spiritual realm, back home to His throne in the Kingdom of Heaven.  No Jew took His picture. No Jew were permitted to make an image or a statue out of Him.
