O thou who hast fixed thy gaze upon My countenance! Admonish
men to fear God. By God! This fear is the chief commander of the army of thy
Lord. Its hosts are a praiseworthy character and goodly deeds. Through it have
the cities of men’s hearts been opened throughout the ages and centuries, and
the standards of ascendancy and triumph raised above all other standards.
- Baha’u’llah (‘Epistle to Son of the Wolf’)
