In Margaret Atwood's novel "The Robber Bride," the protagonist's interpretation of holiness is depicted through the metaphor of a glowing heart, specifically that of Jesus. This imagery suggests that holiness carries a unique radiance, symbolizing purity and divinity. The narrative implies that holy entities possess an inherent luminosity that distinguishes them from the ordinary world.

This concept extends beyond just the figure of Jesus; it resonates with the idea that all sacred or virtuous things exude their own light. Atwood's exploration of holiness reveals how individuals or beliefs that embody righteousness can inspire and uplift, creating a profound impact on those who encounter them.
