“Bestir yourselves, O people, in anticipation of the days of Divine Justice, for the promised hour is now come.”

“Bestir yourselves, O people,” is, on the one hand, the ominous warning sounded by Bahá’u’lláh Himself, “in anticipation of the days of Divine Justice, for the promised hour is now come.” “Abandon that which ye possess, and seize that which God, Who layeth low the necks of men, hath brought. Know ye of a certainty that if ye turn not back from that which ye have committed, chastisement will overtake you on every side, and ye shall behold things more grievous than that which ye beheld aforetime.” And again: “We have fixed a time for you, O people! If ye fail, at the appointed hour, to turn towards God, He, verily, will lay violent hold on you, and will cause grievous afflictions to assail you from every direction. How severe indeed is the chastisement with which your Lord will then chastise you!” And again: “God assuredly dominateth the lives of them that wronged Us, and is well aware of their doings. He will most certainly lay hold on them for their sins. He, verily, is the fiercest of Avengers.” And finally: “O ye peoples of the world! Know verily that an unforeseen calamity is following you and that grievous retribution awaiteth you. Think not the deeds ye have committed have been blotted from My sight. By My Beauty! All your doings hath My pen graven with open characters upon tablets of chrysolite.”
