The Parable of the Prodigal Son is illustrated several times in this allegorical children’s story. Little Milly’s innocent understanding of the Bible became the simple wisdom that was needed by the adults around her. The Probable Son as she calls it, is the substance of her hopes and her prayers throughout the story. I tell you the truth, anyone who will not receive the kingdom of God like a little child will never enter it. -John 10:15.
