The “human world will adapt itself to a new social form” as a result of the “manifestation of spiritual forces” brought forth by Baha’u’llah

Still today, can anyone claim to have glimpsed anything but an intimation, distant and indistinct, of the future society to which the Revelation of Baha'u'llah is destined to give rise? For let none suppose that the civilization towards which the divine teachings impel humankind will follow merely from adjustments to the present order. Far from it. In a talk delivered some days after He laid the cornerstone of the Mother Temple of the West, 'Abdu'l-Baha stated that "among the results of the manifestation of spiritual forces will be that the human world will adapt itself to a new social form," that "the justice of God will become manifest throughout human affairs". These, and countless other utterances of the Master to which the Baha'i community is turning time and again in this centennial period, raise awareness of the distance that separates society as it is now arranged from the stupendous vision His Father gifted to the world.
