One amongst His [Baha’u’llah’s] Teachings is this, that love
and good faith must so dominate the human heart that men will regard the
stranger as a familiar friend, the malefactor as one of their own, the alien
even as a loved one, the enemy as a companion dear and close…The meaning is that
they must treat all humankind even as they treat their sympathizers, their
fellow-believers, their loved ones and familiar friends.
