Illustrate a scene inspired by a key passage from the Christian scriptures, specifically Mark 10:14. Show a compassionate figure with long hair and traditional Middle Eastern attire, inviting a diverse group of children of various descents such as Hispanic, South Asian, Middle Eastern, Black, and Caucasian, to approach him. The demeanor of the figure should be welcoming and affectionate, emphasizing gentleness and kindness. Ensure the style resonates with the pointillism technique famous in the art era of late 19th century, employing multitudes of individual dots of color to create the scene. The atmosphere should be respectful, serene, and devotional without incorporating any textual elements.
