The Advent of Divine Justice is a letter from Shoghi Effendi to the Baháʼís of the United States and Canada written on 25 December 1938. It describes the unique spiritual destiny of America, its role in establishing the Most Great Peace and the crucial contribution that American Baháʼís have to make to that process.

Shoghi Effendi explains that in order for the Baháʼís to make a lasting contribution and fulfill their destiny, they must exert themselves to manifest "moral rectitude," "absolute chastity," and "complete freedom from prejudice."
