‘Abdu’l-Bahá spoke with many people in Denver and told each what they needed to hear. To one He said: “I have come to your city and found tall buildings and advancement in material civilization. Now I will lead you to my own city which is the world above. It’s administration is the oneness of humanity, its law is international peace, its palaces are ever shining with the lights of the Kingdom, it’s season is always spring, its trees are ever green, its fruits are fresh and sweet, it’s sun is ever ascending, its moon is always full, it stars are ever brilliant and its planets are ever circling. That is our city and the founder is Bahá’u’lláh. We‘ve enjoyed the pleasures of this city and now I invite you to that city. I hope you will accept this invitation.
(Earl Redman, ‘Abdu’l-Bahá in Their Midst, p. 205)
