O people! Fear God, and disbelieve not in Him Whose grace hath surrounded all things, Whose mercy hath pervaded the contingent world, and the sovereign potency of Whose Cause hath encompassed both your inner and your outer beings, both your beginning and your end. Stand ye in awe of the Lord, and be of them that act uprightly. Beware lest ye be accounted among those who allow the verses of their Lord to pass them by unheard and unrecognized; these, truly, are of the wayward.
O Temple of Divine Revelation! Sound the trumpet in My Name! O Temple of Divine mysteries! Raise the clarion call of Thy Lord, the Unconditioned, the Unconstrained! O Maid of Heaven! Step forth from the chambers of paradise and announce unto the people of the world: By the righteousness of God! He Who is the Best-Beloved of the worlds — He Who hath ever been the Desire of every perceiving heart, the Object of the adoration of all that are in heaven and on earth, and the Cynosure of the former and the latter generations — is now come!
Beware lest human learning debar thee from Him Who is the Supreme Object of all knowledge, or lest the world deter thee from the One Who created it and set it upon its course. Arise in the name of thy Lord, the God of Mercy, amidst the peoples of the earth, and seize thou the Cup of Life with the hands of confidence. First drink thou therefrom, and proffer it then to such as turn towards it amongst the peoples of all faiths. Thus hath the Moon of Utterance risen above the horizon of wisdom and understanding.

The people of the Qur’án have risen against Us, and tormented Us with such a torment that the Holy Spirit lamented, and the thunder roared out, and the clouds wept over Us. Among the faithless is he who hath imagined that calamities can deter Baha from fulfilling that which God, the Creator of all things, hath purposed. Say: Nay, by Him Who causeth the rain to fall! Nothing whatsoever can withhold Him from the remembrance of His Lord.
Though threatened by the swords of Our enemies, We summon all mankind unto God, the Fashioner of earth and heaven, and We render Him such aid as can be hindered by neither the hosts of tyranny nor the ascendancy of the people of iniquity. Say: O peoples of the earth! Scatter the idols of your vain imaginings in the name of your Lord, the All-Glorious, the All-Knowing, and turn ye unto Him in this Day which God hath made the King of days.
Say: We have ordained that our Cause be taught through the power of utterance. Beware lest ye dispute idly with anyone. Whoso ariseth wholly for the sake of his Lord to teach His Cause, the Holy Spirit shall strengthen him and inspire him with that which will illumine the heart of the world, how much more the hearts of those who seek Him. O people of Baha! Subdue the citadels of men’s hearts with the swords of wisdom and of utterance. They that dispute, as prompted by their desires, are indeed wrapped in a palpable veil. Say: The sword of wisdom is hotter than summer heat, and sharper than blades of steel, if ye do but understand. Draw it forth in My name and through the power of My might, and conquer then with it the cities of the hearts of them that have secluded themselves in the stronghold of their corrupt desires. Thus biddeth you the Pen of the All-Glorious, whilst seated beneath the swords of the wayward.
If ye become aware of a sin committed by another, conceal it, that God may conceal your own sin. He, verily, is the Concealer, the Lord of grace abounding. O ye rich ones on earth! If ye encounter one who is poor, treat him not disdainfully. Reflect upon that whereof ye were created. Every one of you was created of a sorry germ. It behoveth you to observe truthfulness, whereby your temples shall be adorned, your names uplifted, your stations exalted amidst men, and a mighty recompense assured for you before God.
Know also that the soul is endowed with two wings: should it soar in the atmosphere of love and contentment, then it will be related to the All-Merciful. And should it fly in the atmosphere of self and desire, then it will pertain to the Evil One; may God shield and protect us and protect you therefrom, O ye who perceive! Should the soul become ignited with the fire of the love of God, it is called benevolent and pleasing unto God, but should it be consumed with the fire of passion, it is known as the concupiscent soul. Thus have We expounded this subject for thee that thou mayest obtain a clear understanding.
It behoveth everyone to traverse this brief span of life with sincerity and fairness. Should one fail to attain unto the recognition of Him Who is the Eternal Truth, let him at least conduct himself with reason and justice. Erelong these outward trappings, these visible treasures, these earthly vanities, these arrayed armies, these adorned vestures, these proud and overweening souls, all shall pass into the confines of the grave, as though into that box. In the eyes of those possessed of insight, all this conflict, contention and vainglory hath ever been, and will ever be, like unto the play and pastimes of children. Take heed, and be not of them that see and yet deny.
Know ye that the world and its vanities and its embellishments shall pass away. Nothing will endure except God’s Kingdom which pertaineth to none but Him, the Sovereign Lord of all, the Help in Peril, the All-Glorious, the Almighty. The days of your life shall roll away, and all the things with which ye are occupied and of which ye boast yourselves shall perish, and ye shall, most certainly, be summoned by a company of His angels to appear at the spot where the limbs of the entire creation shall be made to tremble, and the flesh of every oppressor to creep. Ye shall be asked of the things your hands have wrought in this, your vain life, and shall be repaid for your doings. This is the day that shall inevitably come upon you, the hour that none can put back. To this the Tongue of Him that speaketh the truth and is the Knower of all things hath testified.
Know ye that I am afraid of none except God. In none but Him have I placed My trust; to none will I cleave but Him, and wish for naught except the thing He hath wished for Me. This, indeed, is My heart’s desire, did ye but know it. I have offered up My soul and My body as a sacrifice for God, the Lord of all worlds. Whoso hath known God shall know none but Him, and he that feareth God shall be afraid of no one except Him, though the powers of the whole earth rise up and be arrayed against him. I speak naught except at His bidding, and follow naught, through the power of God and His might, except His truth. He, verily, shall recompense the truthful.
