C.s. Lewis said this quote

Images of the Holy easily become holy images -- sacrosanct. My idea of God is not a divine idea. It has to be shattered time after time. He shatters it Himself. He is the great iconoclast. Could we not almost say that this shattering is one of the marks His presence? The Incarnation is the supreme example, it leads all previous idea of the Messiah in ruins.
