That of God
What Quakers mean by the Inner Light.
Many Quakers, also called Friends, speak of "that of God" in every person. The phrase points toward a shared vision of the Divine: look for the sacred worth of a person before accepting the world's smallest description of them.
It's not just sentimental optimism. It is a way of seeing, listening, and engaging the world within and without, especially when fear, anger, shame, or judgment makes that difficult.
