Generate an image illustrating a key moment from Christianity where a man, depicted in Middle-Eastern descent, emerges from the water, having just been baptized. The heavens above him open up and a bright, divine light shines upon him. A spirit symbol, in the form of a dove, is descending from the light towards him. The image should embody respect and devotion, facilitating an atmosphere of contemplation and reverence. This should be showcased in the detailed art technique of pointillism, an art movement from the late nineteenth century, using distinct dots to create the artwork.
