A visual representation of the biblical scene from Matthew 18:23-34, encapsulating the forgiving king and an unforgiving servant. The art piece should employ a pointillism technique to emphasize the distinct dots of pure color, reminiscent of artists like Georges Seurat who's work falls prior to the 1912 cut-off. The artwork should carry a respectful and devotional tone towards Christianity. Symbols, characters, and settings should appropriately represent the religious context. Please avoid the usage of any text or words within the image.
