A Christian-themed visual representation unfolding the scene of devotion and joy at the revealing of Joseph to his brothers, from the Biblical reference Genesis 45:14. The image should depict this sacred moment while applying the pointillism technique - an art style that flourished in the late 19th century, characterized by small, distinct, densely packed dots of color to form the image. It is crucial that the execution of this artwork respects the sacred nature of religion and Christian beliefs. No text or words should be included in the image, keeping the focus solely on the spiritual narrative.
