 "It is incumbent upon every man, in this Day, to hold fast unto whatsoever will promote the interests,  and exalt the station, of all nations and just governments. Through each and every one of the verses which the Pen of the Most High hath revealed, the doors of love and unity have been unlocked and flung open to the face of men. We have erewhile declared—and Our Word is the truth—:

“Consort with the followers of all religions in a spirit of friendliness and fellowship.” Whatsoever hath led the children of men to shun one another, and hath caused dissensions and divisions amongst them, hath, through the revelation of these words, been nullified and abolished. From the heaven of God’s Will, and for the purpose of ennobling the world of being and of elevating the minds and souls of men, hath been sent down that which is the most effective instrument for the education of the whole human race. The highest essence and most perfect expression of whatsoever the peoples of old have either said or written hath, through this most potent Revelation, been sent down from the heaven of the Will of the All-Possessing, the Ever-Abiding God. Of old it hath been revealed: “Love of one’s country is an element of the Faith of God.”
The Tongue of Grandeur hath, however, in the day of His manifestation proclaimed: “It is not his to boast who loveth his country, but it is his who loveth the world.”

On another occasion He defined a Bahá’í as “one endowed with all the perfections of man in activity.”
In one of His London talks He said that a man may be a Bahá’í even if He has never heard the name of Bahá’u’lláh. He added:— The man who lives the life according to the teachings of Bahá’u’lláh is already a Bahá’í. On the other hand, a man may call himself a Bahá’í for fifty years, and if he does not live the life he is not a Bahá’í. An ugly man may call himself handsome, but he deceives no one, ...

Bahá’u’lláh and the New Era

Man reacheth perfection through ...

To state the matter briefly, the Teachings of Bahá’u’lláh advocate voluntary sharing, and this is a
greater thing than the equalization of wealth. For equalization must be imposed from without, while sharing is a matter of free choice.
Man reacheth perfection through good deeds, voluntarily performed, not through good deeds the doing of which was forced upon him. And sharing is a personally chosen righteous act: that is, the rich should extend assistance to the poor, they should expend their substance for the poor, but of their own free will, and not because the poor have gained this end by force.
For the harvest of force is turmoil and the ruin of the social order.
On the other hand voluntary sharing, the freely-chosen expending of one’s substance, leadeth to society’s comfort and peace. It lighteth up the world; it bestoweth honour upon humankind...
