Know verily that the purpose underlying all these symbolic terms and abstruse allusions, which emanate from the revealers of Gods holy cause, hath been to test and prove the peoples of the world; that thereby the earth of the pure and illuminated hearts may be known from the perishable and barren soil.
Bahá'u'lláhSince We have created you all from one same substance it is incumbent on you to be even as one soul, to walk with the same feet, eat with the same mouth and dwell in the same land, that from your inmost being, by your deeds and actions, the signs of oneness and the essence of detachment may be made manifest. Such is My counsel to you, O concourse of light!
Bahá'u'lláhThat one indeed is a man who, today, dedicateth himself to the service of the entire human race. The Great Being saith: Blessed and happy is he that ariseth to promote the best interests of the peoples and kindreds of the earth. It is not for him to pride himself who loveth his own country, but rather for him who loveth the whole world. The earth is but one country, and mankind its citizens.
Bahá'u'lláh
