Stage of maturity "the oneness of mankind"

"“All created things,” ‘Abdu’l-Bahá, elucidating this truth, has affirmed, “have their degree or stage of maturity. The period of maturity in the life of a tree is the time of its fruit-bearing…. The animal attains a stage of full growth and completeness, and in the human kingdom man reaches his maturity when the light of his intelligence attains its greatest power and development.  …
Similarly there are periods and stages in the collective life of humanity. At one time it was passing through its stage of childhood, at another its period of youth, but now it has entered its long-predicted phase of maturity, the evidences of which are everywhere apparent….
That which was applicable to human needs during the early history of the race can neither meet nor satisfy the demands of this day, this period of newness and consummation. Humanity has emerged from its former state of limitation and preliminary training. Man must now become imbued with new virtues and powers, new moral standards, new capacities. "

“In every Dispensation,” He moreover has written, “the light of Divine Guidance has been focused upon one central theme…. In this wondrous Revelation, this glorious century, the foundation of the Faith of God, and the distinguishing feature of His Law, is the consciousness of the oneness of mankind.”

The Great Age to Come

Just as the organic evolution of mankind has been slow and gradual, and involved successively the unification of the family, the tribe, the city-state, and the nation, so has the light vouchsafed by the Revelation of God, at various stages in the evolution of religion, and reflected in the successive Dispensations of the past, been slow and progressive.

Indeed the measure of Divine Revelation, in every age, has been adapted to, and commensurate with, the degree of social progress achieved in that age by a constantly evolving humanity.

civilization,” recalling such times in which “religions have perished and are born,” is the adolescent stage in the slow and painful evolution of humanity, preparatory to the attainment of the stage of manhood, the stage of maturity, the promise of which is embedded in the teachings, and enshrined in the prophecies, of Bahá’u’lláh.
The tumult of this age of transition is characteristic of the impetuosity and irrational instincts of youth, its follies, its prodigality, its pride, its self-assurance, its rebelliousness, and contempt of discipline.

Soon, will the present-day order be rolled up

"These strifes and this bloodshed and discord must cease, and all men be as one kindred and one family.” “Soon,” He, Bahá’u’lláh, predicts, “will the present-day order be rolled up, and a new one spread out in its stead.”

“After a time,” He also has written, “all the governments on earth will change. Oppression will envelop the world. And following a universal convulsion, the sun of justice will rise from the horizon of the unseen realm.”
“The whole earth,” He, moreover, has stated, “is now in a state of pregnancy. The day is approaching when it will have yielded its noblest fruits, when from it will have sprung forth the loftiest trees, the most enchanting blossoms, the most heavenly blessings.”

God’s Purpose

God’s purpose is none other than to usher in, in ways He alone can bring about, and the full significance of which He alone can fathom, the Great, the Golden Age of a long-divided, a long-afflicted humanity. Its present state, indeed even its immediate future, is dark, distressingly dark. Its distant future, however, is radiant, gloriously radiant—so radiant that no eye can visualize it.
 “The winds of despair,” writes Bahá’u’lláh, as He surveys the immediate destinies of mankind, “are, alas, blowing from every direction, and the strife that divides and afflicts the human race is daily increasing. The signs of impending convulsions and chaos can now be discerned, inasmuch as the prevailing order appears to be lamentably defective.”
“Such shall be its plight,” He, in another connection, has declared, “that to disclose it now would not be meet and seemly.” “These fruitless strifes,” He, on the other hand, contemplating the future of mankind, has emphatically prophesied, in the course of His memorable interview with the Persian orientalist, Edward G. Browne, “these ruinous wars shall pass away, and the ‘Most Great Peace’ shall come….

Let each morn be better than its eve ...

... Let each morn be better than its eve and each morrow richer than its yesterday. Man’s merit lieth in service and virtue and not in the pageantry of wealth and riches. Take heed that your words be purged from idle fancies and worldly desires and your deeds be cleansed from craftiness and suspicion.
Dissipate not the wealth of your precious lives in the pursuit of evil and corrupt affection, nor let your endeavours be spent in promoting your personal interest. Be generous in your days of plenty, and be patient in the hour of loss.
Adversity is followed by success and rejoicings follow woe. Guard against idleness and sloth, and cling unto that which profiteth mankind, whether young or old, whether high or low. Beware lest ye sow tares of dissension among men or plant thorns of doubt in pure and radiant hearts....
