Create a watercolor depiction of a scene from the Bible, specifically from Matthew 4:4. The image should convey the spiritual message, 'Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.' without the use of textual elements. Perhaps show a man not just eating bread but also seemingly nourished by divine, ethereal light or vibrations representing the word of God. Draped in a humble robe and looking absorbed in spiritual enlightenment, the man should be contented. Honor Christian values and ensure the depiction is respectful and devotional.
