Moses said: "thou shalt not make any ... likeness [to worship it]."
John tells us that the Word became flesh and dwelt among us, but John does not provide an insight drawing: Instead John writes:
We beheld his glory the glory, as of the only begotton of the Father, full of grace and truth.
That glory is still visible in the pages of Scripture, but is mocked and obscured in gilt paintings.
As Paul put it:
2 Corinthians 4:3-6
3But if our gospel be hid, it is hid to them that are lost: 4In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them. 5For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake. 6For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
So then it is by the preached word that we see Jesus, not by gazing at an idol.
