God hath prescribed unto every one the duty of teaching His
Cause. Whosoever ariseth to discharge this duty must needs, ere he proclaimeth
His Message, adorn himself with the ornament of an upright and praiseworthy
character, so that his words may attract the hearts of such as are receptive to
his call. Without it, he can never hope to influence his hearers. - Baha'u'llah (‘Gleanings from the Writings of Baha'u'llah’)
