“The Day of the Promise is come, and He Who is the Promised One loudly proclaimeth before all who are in heaven and all who are on earth, ‘Verily there is none other God but He, the Help in Peril, the Self-Subsisting!’ "

“Verily I say! No one hath apprehended the root of this Cause. It is incumbent upon everyone, in this day, to perceive with the eye of God, and to hearken with His ear. Whoso beholdeth Me with an eye besides Mine own will never be able to know Me. None among the Manifestations of old, except to a prescribed degree, hath ever completely apprehended the nature of this Revelation.” “I testify before God to the greatness, the inconceivable greatness of this Revelation. Again and again have We, in most of Our Tablets, borne witness to this truth, that mankind may be roused from its heedlessness.” “How great is the Cause, how staggering the weight of its Message!” “In this most mighty Revelation all the Dispensations of the past have attained their highest, their final consummation.” “That which hath been made manifest in this preeminent, this most exalted Revelation, stands unparalleled in the annals of the past, nor will future ages witness its like.” “The purpose underlying all creation is the revelation of this most sublime, this most holy Day, the Day known as the Day of God, in His Books and Scriptures—the Day which all the Prophets, and the Chosen Ones, and the holy ones, have wished to witness.” “The highest essence and most perfect expression of whatsoever the peoples of old have either said or written hath, through this most potent Revelation, been sent down from the heaven of the Will of the All-Possessing, the Ever-Abiding God.” “This is the Day in which God’s most excellent favors have been poured out upon men, the Day in which His most mighty grace hath been infused into all created things.” “This is the Day whereon the Ocean of God’s mercy hath been manifested unto men, the Day in which the Daystar of His loving-kindness hath shed its radiance upon them, the Day in which the clouds of His bountiful favor have overshadowed the whole of mankind.” “By the righteousness of Mine own Self! Great, immeasurably great is this Cause! Mighty, inconceivably mighty is this Day!” “Every Prophet hath announced the coming of this Day, and every Messenger hath groaned in His yearning for this Revelation—a revelation which, no sooner had it been revealed than all created things cried out saying, ‘The earth is God’s, the Most Exalted, the Most Great!’” “The Day of the Promise is come, and He Who is the Promised One loudly proclaimeth before all who are in heaven and all who are on earth, ‘Verily there is none other God but He, the Help in Peril, the Self-Subsisting!’ "
