Create an image that symbolically portrays Romans 1:16, 'For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to everyone that believeth; to the Jew first, and also to the Greek.' This image should be rendered in the art style of realism, characteristic of accurate and detailed depiction of visual appearances. It should show a Jew, with physical features like dark curly hair, olive skin, and dressed in traditional attire, and a Greek man, with fair skin and in a toga, both showing reverence towards a luminous cross, signifying the power of God. There must not be any text or words in the image. The artwork should evoke a sense of respect and devotion to Christianity.
