"There was even a time when men were wholly ignorant of the art of writing ..."

"And now regarding thy question, “How is it that no records are to be found concerning the Prophets that have preceded Adam, the Father of Mankind, or of the kings that lived in the days of those Prophets?” Know thou that the absence of any reference to them is no proof that they did not actually exist. That no records concerning them are now available, should be attributed to their extreme remoteness, as well as to the vast changes which the earth hath undergone since their time.

Moreover such forms and modes of writing as are now current amongst men were unknown to the generations that were before Adam. There was even a time when men were wholly ignorant of the art of writing, and had adopted a system entirely different from the one which they now use. For a proper exposition of this an elaborate explanation would be required.
Consider the differences that have arisen since the days of Adam. The divers and widely-known languages now spoken by the peoples of the earth were originally unknown, as were the varied rules and customs now prevailing amongst them. The people of those times spoke a language different from those now known. Diversities of language arose in a later age, in a land known as Babel. It was given the name Babel, because the term signifieth “the place where the confusion of tongues arose.”

Subsequently Syriac became prominent among the existing languages. The Sacred Scriptures of former times were revealed in that tongue. Later, Abraham, the Friend of God, appeared and shed upon the world the light of Divine Revelation. The language He spoke while He crossed the Jordan became known as Hebrew (Ibrání), which meaneth “the language of the crossing.” The Books of God and the Sacred Scriptures were then revealed in that tongue, and not until after a considerable lapse of time did Arabic become the language of Revelation….

" It behoveth you to ascertain whether or not such a light hath appeared."

"Shake off, O heedless ones, the slumber of negligence, that ye may behold the radiance which His glory hath spread through the world. How foolish are those who murmur against the premature birth of His light. O ye who are inly blind! Whether too soon or too late, the evidences of His effulgent glory are now actually manifest. It behoveth you to ascertain whether or not such a light hath appeared. It is neither within your power nor mine to set the time at which it should be made manifest. God’s inscrutable Wisdom hath fixed its hour beforehand. Be content, O people, with that which God hath desired for you and predestined unto you…."

" ... that the leaders of men in every land may fully recognize the purpose .."

"All men have been created to carry forward an ever-advancing civilization. The Almighty beareth Me witness: To act like the beasts of the field is unworthy of man. Those virtues that befit his dignity are forbearance, mercy, compassion and loving-kindness towards all the peoples and kindreds of the earth. Say: O friends! Drink your fill from this crystal stream that floweth through the heavenly grace of Him Who is the Lord of Names. Let others partake of its waters in My name, that the leaders of men in every land may fully recognize the purpose for which the Eternal Truth hath been revealed, and the reason for which they themselves have been created."

-Bahá'u'lláh, Gleanings From the Writings of Bahá’u’lláh, p. 215

"This indeed is the true meaning of Divine Unity ... "

"Beware, O believers in the Unity of God, lest ye be tempted to make any distinction between any of the Manifestations of His Cause, or to discriminate against the signs that have accompanied and proclaimed their Revelation. This indeed is the true meaning of Divine Unity, if ye be of them that apprehend and believe this truth. Be ye assured, moreover, that the works and acts of each and every one of these Manifestations of God, nay whatever pertaineth unto them, and whatsoever they may manifest in the future, are all ordained by God, and are a reflection of His Will and Purpose. Whoso maketh the slightest possible difference between their persons, their words, their messages, their acts and manners, hath indeed disbelieved in God, hath repudiated His signs, and betrayed the Cause of His Messengers."

"This is the day for eyes to see and for ears to hear ..."

"In this day He Who is the Lord, the Ruler, the Fashioner, and the Refuge of the world hath appeared. Let every ear be eager to hearken unto that which will be revealed from the kingdom of His will; let every eye be expectant to gaze upon that which will shine forth from the Daystar of knowledge and wisdom. By Him Who is the Desire of the world! This is the day for eyes to see and for ears to hear, for hearts to perceive and for tongues to speak forth. Blessed are they that have attained thereunto; blessed are they that have sought after and recognized it! This is the day whereon every man may accede unto everlasting honour, for whatsoever hath streamed forth from the Pen of Glory in regard to any soul is adorned with the ornament of immortality. Again, blessed are they that have attained thereunto!"

"The source of all good is ..."

"The source of all good is trust in God, submission unto His command, and contentment with His holy will and pleasure."

"The essence of true safety ..."

"The essence of true safety is to observe silence, to look at the end of things and to renounce the world."
