no one had really seen God, except for a few priviledge ones
like Abraham.
so how can one really have an accurate painting? well, most artist
just simply express it as in how he/she sees God to be. To some He
is the Ancient of Days, to others he is the Kind and Loving Father,
and yet others, He is the Majestic King. How each artist sees God
determine how they express Him in their paintings.
*if you want to see an image of God? you can go look into the
mirror, cause, you are created in His Image.
Genesis 1:27
So God created man in his own image,
in the image of God he created him;
male and female he created them.
God bless
