The companions of God are, in this day, the lump that must
leaven the peoples of the world. They must show forth such trustworthiness,
such truthfulness and perseverance, such deeds and character that all mankind
may profit by their example… I swear by Him Who is the Most Great Ocean! Within
the very breath of such souls as are pure and sanctified far-reaching
potentialities are hidden. So great are these potentialities that they exercise
their influence upon all created things.
(Baha’u’llah, quoted by Shoghi
Effendi in ‘The Advent of Divine Justice)
