Post tenebras lux

Post tenebras lux is a Latin phrase translated as Light After Darkness. It appears as Post tenebras spero lucem ("After darkness, I hope for light") in the Vulgate version of Job 17:12.

The phrase came to be adopted as the Calvinist motto, and was subsequently adopted as the motto of the entire Protestant Reformation. It is used by John Calvin's adopted city of Geneva, Switzerland on their coins.
