A symbolic scene based on the principle from Exodus 14:14, 'The Lord will fight for you; you need only to be still'. Create a serene illustration in the style of a watercolor painting. Perhaps depict a peaceful yet strong figure, glowing and radiant in the scene, engaged in a battle unseen. The scene should be filled with calmness that reflects the 'being still' concept. No text or words included in the image. Make sure the scene is respectful and pays homage to Christian belief and ethos.
