Blessed is he who in the prime of his youth and the heyday of his life will arise to serve the Cause of the Lord of the beginning and of the end, and adorn his heart with His love. The manifestation of such a grace is greater than the creation of the heavens and of the earth. Blessed are the steadfast and well is it with those who are firm. 
(Baha’u’llah, The Compilation of Compilations, vol. II, Youth)

Blessed is the spot, and the house, and the place, and the city, and the heart, and the mountain, and the refuge, and the cave, and the valley, and the land, and the sea, and the island, and the meadow where mention of God hath been made, and His praise glorified.

Knowledge is one of the wondrous gifts of God. It is incumbent upon everyone to acquire it. Such arts and material means as are now manifest have been achieved by virtue of His knowledge and wisdom which have been revealed in Epistles and Tablets through His Most Exalted Pen – a Pen out of whose treasury pearls of wisdom and utterance and the arts and crafts of the world are brought to light.

Whilst in the Prison of 'Akká, We revealed in the Crimson Book that which is conducive to the advancement of mankind and to the reconstruction of the world. The utterances set forth therein by the Pen of the Lord of creation include the following which constitute the fundamental principles for the administration of the affairs of men:

First: It is incumbent upon the ministers of the House of Justice to promote the Lesser Peace so that the people of the earth may be relieved from the burden of exorbitant expenditures. This matter is imperative and absolutely essential, inasmuch as hostilities and conflict lie at the root of affliction and calamity.

Second: Languages must be reduced to one common language to be taught in all the schools of the world.

Third: It behoveth man to adhere tenaciously unto that which will promote fellowship, kindliness and unity.

Fourth: Everyone, whether man or woman, should hand over to a trusted person a portion of what he or she earneth through trade, agriculture or other occupation, for the training and education of children, to be spent for this purpose with the knowledge of the Trustees of the House of Justice.

Fifth: Special regard must be paid to agriculture. Although it hath been mentioned in the fifth place, unquestionably it precedeth the others.

Blessed is he who, at the hour of dawn, centring his thoughts on God, occupied with His remembrance, and supplicating His forgiveness, directeth his steps to the Mashriqu'l-Adhkár and, entering therein, seateth himself in silence to listen to the verses of God, the Sovereign, the Mighty, the All-Praised. Say: The Mashriqu'l-Adhkár is each and every building which hath been erected in cities and villages for the celebration of My praise. Such is the name by which it hath been designated before the throne of glory, were ye of those who understand. 
(Baha’u’llah, the Kitab-i-Aqdas)

December 26th

Should a man wish to adorn himself with the ornaments of the earth, to wear its apparels, or partake of the benefits it can bestow, no harm can befall him, if he alloweth nothing whatever to intervene between him and God, for God hath ordained every good thing, whether  created in the heavens or in the earth, for such of His servants as truly believe in Him. Eat ye, O people, of the good things which God hath allowed you, and deprive not yourselves from His wondrous bounties. Render thanks and praise unto Him, and be of them that are truly thankful.

December 25th

This is the Day in which God's most excellent favours have been poured out upon men, the Day in which His most mighty grace hath been infused into all created things. It is incumbent upon all the peoples of the world to reconcile their differences, and, with perfect unity and peace, abide beneath the shadow of the Tree of His care and loving-kindness. It behoveth them to cleave to whatsoever will, in this Day, be conducive to the exaltation of their stations, and to the promotion of their best interests....

December 24

Man is even as steel, the essence of which is hidden: through admonition and explanation, good counsel and education, that essence will be brought to light. If, however, he be allowed to remain in his original condition, the corrosion of lusts and appetites will effectively destroy him. 
(Baha’u’llah, ‘The Compilation of Compilations’, vol. I, Baha’i Education)

December 23

Know ye that trials and tribulations have, from time immemorial, been the lot of the chosen Ones of God and His beloved, and such of His servants as are detached from all else but Him, they whom neither merchandise nor traffic beguile from the remembrance of the Almighty, they that speak not till He hath spoken, and act according to His commandment. Such is God's method carried into effect of old, and such will it remain in the future....

December 22

Teach ye your children so that they may peruse the divine verses every morn and eve. God hath prescribed unto every father to educate his children, both boys and girls, in the sciences and in morals, and in crafts and professions.... (Baha’u’llah, The Compilation of Compilations, vol. 1, Extracts from the Writings concerning arts and crafts)

December 21

Consider ... the revelation of the light of the Name of God, the Educator. Behold, how in all things the evidences of such a revelation are manifest, how the betterment of all beings dependeth upon it. This education is of two kinds. The one is universal. Its influence pervadeth all things and sustaineth them. It is for this reason that God hath assumed the title, "Lord of all worlds". The other is confined to them that have come under the shadow of this Name, and sought the shelter of this most mighty Revelation. They, however, that have failed to seek this shelter, have deprived themselves of this privilege, and are powerless to benefit from the spiritual sustenance that hath been sent down through the heavenly grace of this Most Great Name. How great the gulf fixed between the one and the other!... (Baha’u’llah, ‘Gleanings from the Writings of Bahá'u'lláh’; The Compilation of Compilations, vol. I, Baha’i Education)

December 20

One of the names of God is the Fashioner. He loveth craftsmanship. Therefore any of His servants who manifesteth this attribute is acceptable in the sight of this Wronged One. Craftsmanship is a book among the books of divine sciences, and a treasure among the treasures of His heavenly wisdom. This is a knowledge with meaning, for some of the sciences are brought forth by words and come to an end with words. (Baha’u’llah, The Compilation of Compilations, vol. I, Arts and crafts)

December 19

… whatever I behold I readily discover that it maketh Thee known unto me, and it remindeth me of Thy signs, and of Thy tokens, and of Thy testimonies. By Thy glory! Every time I lift up mine eyes unto Thy heaven, I call to mind Thy highness and Thy loftiness, and Thine incomparable glory and greatness; and every time I turn my gaze to Thine earth, I am made to recognize the evidences of Thy power and the tokens of Thy bounty. And when I behold the sea, I find that it speaketh to me of Thy majesty, and of the potency of Thy might, and of Thy sovereignty and Thy grandeur. And at whatever time I contemplate the mountains, I am led to discover the ensigns of Thy victory and the standards of Thine omnipotence.

December 18

The Great Being saith: The heaven of divine wisdom is illumined with the two luminaries of consultation and compassion. Take ye counsel together in all matters, inasmuch as consultation is the lamp of guidance which leadeth the way, and is the bestower of understanding. (Baha’u’llah, ‘Tablets of Bahá'u'lláh Revealed after the Kitáb-i-Aqdas’; The Compilation of Compilations, vol. I, Consultation)

December 17

They whom God hath endued with insight will readily recognize that the precepts laid down by God constitute the highest means for the maintenance of order in the world and the security of its peoples....

December 16

The Prophets and Messengers of God have been sent down for the sole purpose of guiding mankind to the straight Path of Truth. The purpose underlying their revelation hath been to educate all men, that they may, at the hour of death, ascend, in the utmost purity and sanctity and with absolute detachment, to the throne of the Most High....
