“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

December 31

By Him Who shineth above the Dayspring of Sanctity! The friends of God have not, nor will they ever, set their hopes upon the world and its ephemeral possessions. The one true God hath ever regarded the hearts of men as His own, His exclusive possession—and this too but as an expression of His all-surpassing mercy, that haply mortal souls may be purged and sanctified from all that pertaineth to the world of dust and gain admittance into the realms of eternity. 
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)

December 30

That Sovereign Lord [God] Who doeth whatsoever He pleaseth hath entrusted the kingdom of creation, its lands and its seas, into the hands of the kings, for they are, each according to his degree, the manifestations of His divine power.  Should they enter beneath the shadow of the True One, they will be accounted of God, and if not, thy Lord, verily, knoweth and observeth all things.  
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)

December 29

That which God — glorified be His Name! —hath desired for Himself is the hearts of His servants, which are the treasuries of His love and remembrance and the repositories of His knowledge and wisdom.  It hath ever been the wish of the Eternal King to cleanse the hearts of His servants from the things of the world and all that pertaineth thereunto, that they may be made worthy recipients of the effulgent splendours of Him Who is the King of all names and attributes.  Wherefore must no stranger be allowed in the city of the heart, that the incomparable Friend may enter His abode.  By this is meant the effulgence of His names and attributes, and not His exalted Essence, inasmuch as that peerless King hath ever been, and shall eternally remain, sanctified above ascent and descent. 
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)

December 28

The Great Being saith: The structure of world stability and order hath been reared upon, and will continue to be sustained by, the twin pillars of reward and punishment. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)

December 27

I swear by God, O King! Wert thou to incline thine ear to the melodies of that Nightingale which warbleth in manifold accents upon the mystic bough as bidden by thy Lord, the All-Merciful, thou wouldst cast away thy sovereignty and set thy face towards this Scene of transcendent glory, above whose horizon shineth the Book of the Dawntide, and wouldst expend all that thou possessest in thine eagerness to obtain the things of God. Then wouldst thou find thyself raised up to the summit of exaltation and glory, and elevated to the pinnacle of majesty and independence. Thus hath the decree been recorded in the Mother Book by the Pen of the All-Merciful.  
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)

December 26

O ye who are invested with the Bayán! Ye shall be put to proof, even as those unto whom the Qur’án was given. Have pity on yourselves, for ye shall witness the Day when God will have revealed Him Who is the Manifestation of His Own Self, invested with clear and irrefutable proofs, while ye will cling tenaciously to the words the Witnesses of the Bayán have uttered. On that Day ye will continue to rove distraught, even as camels, seeking a drop of the water of life. God will cause oceans of living water to stream forth from the presence of Him Whom God shall make manifest, while ye will refuse to quench your thirst therefrom, notwithstanding that ye regard yourselves as the God-fearing witnesses of your Faith. Nay, and yet again, nay! Ye will go astray far beyond the peoples unto whom the Gospel, or the Qur’án or any other Scripture was given. Take good heed to yourselves, inasmuch as the Cause of God will come upon you at a time when you will all be entreating and tearfully imploring God for the advent of the Day of His Manifestation; yet when He cometh ye will tarry and will fail to be of those who are well-assured in His Faith. 
- The Báb  (‘Selections from the Writings of the Báb)

December 25

Know thou that when the Son of Man yielded up His breath to God, the whole creation wept with a great weeping. By sacrificing Himself, however, a fresh capacity was infused into all created things. Its evidences, as witnessed in all the peoples of the earth, are now manifest before thee. The deepest wisdom which the sages have uttered, the profoundest learning which any mind hath unfolded, the arts which the ablest hands have produced, the influence exerted by the most potent of rulers, are but manifestations of the quickening power released by His transcendent, His all-pervasive and resplendent Spirit. 
- Baha’u’llah  (Quoted by Shoghi Effendi in 'The Promised Day is Come')

December 24

We testify that when He [Jesus] came into the world, He shed the splendor of His glory upon all created things. Through Him the leper recovered from the leprosy of perversity and ignorance. Through Him the unchaste and wayward were healed. Through His power, born of Almighty God, the eyes of the blind were opened and the soul of the sinner sanctified.... He it is Who purified the world. Blessed is the man who, with a face beaming with light, hath turned towards Him. 
- Baha’u’llah  (Quoted by Shoghi Effendi in 'The Promised Day is Come')

December 23

If ye wish to distinguish truth from error, consider those who believe in Him Whom God shall make manifest and those who disbelieve Him at the time of His appearance. The former represent the essence of truth, as attested in the Book of God, while the latter the essence of error, as attested in that same Book. Fear ye God that ye may not identify yourselves with aught but the truth, inasmuch as ye have been exalted in the Bayán for being recognized as the bearers of the name of Him Who is the eternal Truth. 
- The Báb  (‘Selections from the Writings of the Báb’)

December 22

We beseech God to strengthen thee with His power, and enable thee to recognize Him Who is the Source of all knowledge, that thou mayest detach thyself from all human learning, for, “what would it profit any man to strive after learning when he hath already found and recognized Him Who is the Object of all knowledge?” Cleave to the Root of Knowledge, and to Him Who is the Fountain thereof, that thou mayest find thyself independent of all who claim to be well versed in human learning, and whose claim no clear proof, nor the testimony of any enlightening book, can support. 
- Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’)

December 21

Oh, would that the world could believe Me! Were all the things that lie enshrined within the heart of Bahá, and which the Lord, His God, the Lord of all names, hath taught Him, to be unveiled to mankind, every man on earth would be dumbfounded.

How great the multitude of truths which the garment of words can never contain! How vast the number of such verities as no expression can adequately describe, whose significance can never be unfolded, and to which not even the remotest allusions can be made! How manifold are the truths which must remain unuttered until the appointed time is come! Even as it hath been said: “Not everything that a man knoweth can be disclosed, nor can everything that he can disclose be regarded as timely, nor can every timely utterance be considered as suited to the capacity of those who hear it.”

Of these truths some can be disclosed only to the extent of the capacity of the repositories of the light of Our knowledge, and the recipients of Our hidden grace.
- Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’)

December 20

Know assuredly that just as thou firmly believest that the Word of God, exalted be His glory, endureth for ever, thou must, likewise, believe with undoubting faith that its meaning can never be exhausted. They who are its appointed interpreters, they whose hearts are the repositories of its secrets, are, however, the only ones who can comprehend its manifold wisdom. 
- Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’)

December 19

Praise be to Thee, O Lord my God, for guiding me unto the horizon of Thy Revelation… I beseech Thee, by the spreading rays of the Daystar of Thy providence and by the billowing waves of the Ocean of Thy mercy, to grant that my speech may bear a trace of the influence of Thine own exalted Word, attracting thereby the realities of all created things. 
- Baha’u’llah  (New compilation prepared by the Baha’i World Center; Online Baha’i Reference Library of the World Center)

December 18

The Great Being saith: O well-beloved ones! The tabernacle of unity hath been raised; regard ye not one another as strangers. Ye are the fruits of one tree, and the leaves of one branch. We cherish the hope that the light of justice may shine upon the world and sanctify it from tyranny. If the rulers and kings of the earth, the symbols of the power of God, exalted be His glory, arise and resolve to dedicate themselves to whatever will promote the highest interests of the whole of humanity, the reign of justice will assuredly be established amongst the children of men, and the effulgence of its light will envelop the whole earth. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)

December 17

Behold the disturbances which, for many a long year, have afflicted the earth, and the perturbation that hath seized its peoples. It hath either been ravaged by war, or tormented by sudden and unforeseen calamities. Though the world is encompassed with misery and distress, yet no man hath paused to reflect what the cause or source of that may be. Whenever the True Counsellor uttered a word in admonishment, lo, they all denounced Him as a mover of mischief and rejected His claim. How bewildering, how confusing is such behaviour! No two men can be found who may be said to be outwardly and inwardly united. The evidences of discord and malice are apparent everywhere, though all were made for harmony and union. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)

December 16

Take heed, O concourse of the rulers of the world! There is no force on earth that can equal in its conquering power the force of justice and wisdom. I, verily, affirm that there is not, and hath never been, a host more mighty than that of justice and wisdom. Blessed is the king who marcheth with the ensign of wisdom unfurled before him, and the battalions of justice massed in his rear. He verily is the ornament that adorneth the brow of peace and the countenance of security. There can be no doubt whatever that if the day-star of justice, which the clouds of tyranny have obscured, were to shed its light upon men, the face of the earth would be completely transformed. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)

December 15

Illumine, O Lord, the faces of Thy servants, that they may behold Thee; and cleanse their hearts that they may turn unto the court of Thy heavenly favors, and recognize Him Who is the Manifestation of Thy Self and the Day-Spring of Thine Essence. 
- Baha’u’llah  (‘Prayers and Meditations by Baha’u’llah’)

December 14

Be most loving one to another. Burn away, wholly for the sake of the Well-Beloved, the veil of self with the flame of the undying Fire, and with faces joyous and beaming with light, associate with your neighbour... 
- Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’; The Compilation of Compilations, vol. III, Social and Economic Development)

December 13

Should a person acquire one hundred mithqals [1] of gold, nineteen mithqals thereof belong unto God, the Creator of earth and heaven. Take heed, O people, lest ye deprive yourselves of this great bounty. We have prescribed this law unto you while We are wholly independent of you and of all that are in the heavens and on the earth. Indeed there lie concealed in this command, mysteries and benefits which are beyond the comprehension of anyone save God, the All-Knowing, the All-Informed. Say, through this injunction God desireth to purify your possessions and enable you to draw nigh unto such stations as none can attain, except those whom God may please. Verily, He is the Generous, the Gracious, the Bountiful. 
- Baha’u’llah  (The Compilation of Compilation, vol. I, Huqúqu'lláh)
[1] Mithqál is a unit of weight equals to about 3.642 grams.

December 12

No understanding can grasp the nature of His [the Báb’s] Revelation, nor can any knowledge comprehend the full measure of His Faith. All sayings are dependent upon His sanction, and all things stand in need of His Cause. All else save Him are created by His command, and move and have their being through His law. He is the Revealer of the divine mysteries, and the Expounder of the hidden and ancient wisdom. 
- Baha’u’llah  (‘The Kitab-i-Iqan’)
