An elaborate illustration symbolizing the biblical passage from Matthew 18:6. The artwork displays an ancient figure burdened by a sizable millstone hung around his neck, teetering on the edge of a tumultuous sea. The figure is contrasted by innocent children who emanate light, signifying faith and purity. The children observe the weighted figure from a safe distance, their faces filled with concern and compassion. The surroundings are like a scenery from the biblical era, with lush landscapes and old architectural structures. The sea beneath the figure is depicted as deep and frightening, roiling with waves and darkened by storms. Render this scene in a detailed, digital art style.
