A respectful and devotional scene depicting the essence of the biblical verse Exodus 14:14 - 'The Lord will fight for you; you need only to be still.' Focus on illustrating this concept with symbolic Christian elements such as a radiant cross radiating divine light fighting off encroaching shadow, or palpable divine intervention in a chaotic situation. This scene should be in a watercolor style. Please do not include any text or words in the image.
