Create an image with a devotional tone to Christianity, showing two distinct figures standing near a furnace. One figure holds a handful of ashes up towards the heavens, and both figures are observing this act with reverence. Note that the two figures are dressed in ancient robes, reflecting the biblical context of the scene. This image is to be crafted in a style akin to concept art, with broad strokes and implications of the surrounding environment, but leaving the focus on the two figures and their dutiful action of sprinkling ashes. Attention should be on the detailed depiction of the ashes soaring towards the sky and the reverent expressions of the figures. No texts or words should be visible in the image.
