Baha'u'llah 'alone' can bring them peace and justice and an ordered life.

“Our task is to build the Order of Bahá’u’lláh. Undeflected by the desperate expedients of those who seek to subdue the storm convulsing human life by political, economic, social or educational programs, let us, with single-minded devotion and concentrating all our efforts on our objective, raise His Divine System and . . . demonstrate the Bahá’í way of life. Wherever a Bahá’í community exists, whether large or small, let it be distinguished for its abiding sense of security and faith, its high standard of rectitude, its complete freedom from all forms of prejudice, the spirit of love among its members and for the closely knit fabric of its social life. The acute distinction between this and present day society will inevitably arouse the interest of the more enlightened, and as the world’s gloom deepens the light of Bahá’í life will shine brighter and brighter until its brilliance must eventually attract the disillusioned masses and cause them to enter the haven of the Covenant of Bahá’u’lláh, Who alone can bring them peace and justice and an ordered life.”
