Exodus 20:23 Ye shall not make with me gods of silver, neither shall ye make unto you gods of gold.
God is bigger than any image could ever picture. He is the Creator God. He stands above all else. He stands on the outside of our entire existence. He is before us and after us.
Do not think that you can understand Him. Do not think that you can help people see Him in anything small you might make. The largest image possible would never show the greatness of a God that creates universes at His word.
He is God. Make not images of Him!
