One righteous act is endowed with a potency that can so
elevate the dust as to cause it to pass beyond the heaven of heavens. It can
tear every bond asunder, and hath the power to restore the force that hath
spent itself and vanished.... Be pure, O people of God, be pure; be righteous,
be righteous.... Say: O people of God! That which can insure the victory of Him
Who is the Eternal Truth, His hosts and helpers on earth, have been set down in
the sacred Books and Scriptures, and are as clear and manifest as the sun.
These hosts are such righteous deeds, such conduct and character, as are
acceptable in His sight. Whoso ariseth, in this Day, to aid Our Cause, and
summoneth to his assistance the hosts of a praiseworthy character and upright
conduct, the influence from such an action will, most certainly, be diffused
throughout the whole world. (Baha’u’llah, quoted by Shoghi Effendi in ‘The
Advent of Divine Justice’)
