A concept art of Galatians 5:16-17 - 'So I say, walk by the Spirit, and you will not gratify the desires of the flesh. For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want.' This image should capture the powerful tension and contrast between the spiritual and the physical, showing two figures, the Spirit represented as ethereal, serene, and light-filled, and the Flesh depicted as material, impassioned, and shadowy. They should face each other, embodying a dynamic yet balanced conflict. Render this scene using modern digital art techniques.
