"reward and punishment"

Justice He [Baha'u'llah] extols as "the light of men" and their "guardian," as "the revealer of the secrets of the world of being, and the standard-bearer of love and bounty"; declares its radiance to be incomparable; affirms that upon it must depend "the organization of the world and the tranquillity of mankind." He characterizes its "two pillars" -- "reward and punishment" -- as "the sources of life" to the human race; warns the peoples of the world to bestir themselves in anticipation of its advent; and prophesies that, after an interval of great turmoil and grievous injustice, its day-star will shine in its full splendor and glory.

The sword of wisdom is hotter than summer heat,...

"Know of a truth that your subjects are God's trust amongst you. Watch ye, therefore, over them as ye watch over your own selves. Beware that ye allow not wolves to become the shepherds of the fold, or pride and conceit to deter you from turning unto the poor and the desolate. Arise thou, in My name, above the horizon of renunciation, and set, then, thy face towards the Kingdom, at the bidding of thy Lord, the Lord of strength and of might." And further We have said: "Deal not treacherously with the substance of your neighbor. Be ye trustworthy on earth, and withhold not from the poor the things given unto you by God through His grace. He, verily, will bestow upon you the double of what ye possess. He, in truth, is the All-Bounteous, the Most Generous. 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."

the purpose of this life is to .....

In considering the effect of obedience to the laws on individual lives, one must remember that the purpose of this life is to prepare the soul for the next. Here one must learn to control and direct one's animal impulses, not to be a slave to them. Life in this world is a succession of tests and achievements, of falling short and of making new spiritual advances. Sometimes the course may seem very hard, but one can witness, again and again, that the soul who steadfastly obeys the law of Baha'u'llah, however hard it may seem, grows spiritually, while the one who compromises with the law for the sake of his own apparent happiness is seen to have been following a chimera: he does not attain the happiness he sought, he retards his spiritual advance and often brings new problems upon himself.

Surih of the Temple

In His [Baha'u' llah] Suratu'l-Haykal (the Surih of the Temple) He thus describes those breathless moments when the Maiden, symbolizing the "Most Great Spirit" proclaimed His mission to the entire creation: "While engulfed in tribulations I heard a most wondrous, a most sweet voice, calling above My head. Turning My face, I beheld a Maiden -- the embodiment of the remembrance of the name of My Lord -- suspended in the air before Me. So rejoiced was she in her very soul that her countenance shone with the ornament of the good-pleasure of God, and her cheeks glowed with the brightness of the All-Merciful. Betwixt earth and heaven she was raising a call which captivated the hearts and minds of men. She was imparting to both My inward and outer being tidings which rejoiced My soul, and the souls of God's honored servants. Pointing with her finger unto My head, she addressed all who are in heaven and all who are on earth, saying: 'By God! This is the Best-Beloved of the worlds, and yet ye comprehend not. This is the Beauty of God amongst you, and the power of His sovereignty within you, could ye but understand. This is the Mystery of God and His Treasure, the Cause of God and His glory unto all who are in the kingdoms of Revelation and of creation, if ye be of them that perceive.'"

Shoghi Effendi,

The light that is shed from the heaven of bounty, and the benediction that shineth from the dawning-place of the will of God, the Lord of the Kingdom of Names, rest upon Him Who is the Supreme Mediator, the Most Exalted Pen, Him Whom God hath made the Dawning-Place of His most excellent names and the Dayspring of His most exalted attributes. Through Him the light of unity hath shone forth above the horizon of the world, and the law of oneness hath been revealed amidst the nations, who, with radiant faces, have turned towards the Supreme Horizon, and acknowledged that which the Tongue of Utterance hath spoken in the kingdom of His knowledge: "Earth and heaven, glory and dominion, are God's, the Omnipotent, the Almighty, the Lord of grace abounding!"

The teaching work .....

The teaching work should under all conditions be actively pursued by the believers because divine confirmations are dependent upon it. Should a Bahá'í refrain from being fully, vigorously and wholeheartedly involved in the teaching work he will undoubtedly be deprived of the blessings of the Abhá Kingdom. Even so, this activity should be tempered with wisdom--not that wisdom which requireth one to be silent and forgetful of such an obligation, but rather that which requireth one to display divine tolerance, love, kindness, patience, a goodly character, and holy deeds. In brief, encourage the friends individually to teach the Cause of God and draw their attention to this meaning of wisdom mentioned in the Writings, which is itself the essence of teaching the Faith--but all this to be done with the greatest tolerance, so that heavenly assistance and divine confirmation may aid the friends.

the power of thought is dependent on its manifestation in deeds.

Some men and women glory in their exalted thoughts, but if these thoughts never reach the plane of action they remain useless: the power of thought is dependent on its manifestation in deeds. A philosopher's thought may, however, in the world of progress and evolution, translate itself into the actions of other people, even when they themselves are unable or unwilling to show forth their grand ideals in their own lives. To this class the majority of philosophers belong, their teachings being high above their actions. This is the difference between philosophers who are Spiritual Teachers, and those who are mere philosophers: the Spiritual Teacher is the first to follow His own teaching; He brings down into the world of action His spiritual conceptions and ideals. His Divine thoughts are made manifest to the world. His thought is Himself, from which He is inseparable. When we find a philosopher emphasizing the importance and grandeur of justice, and then encouraging a rapacious monarch in his oppression and tyranny, we quickly realize that he belongs to the first class: for he thinks heavenly thoughts and does not practise the corresponding heavenly virtues.

'Abdu'l-Baha,

.....polish the mirrors of hearts....

The light of the sun becomes apparent in each object according to the capacity of that object. The difference is simply one of degree and receptivity. The stone would be a recipient only to a limited extent; another created thing might be as a mirror wherein the sun is fully reflected; but the same light shines upon both.

The most important thing is to polish the mirrors of hearts in order that they may become illumined and receptive of the divine light. One heart may possess the capacity of the polished mirror; another, be covered and obscured by the dust and dross of this world. Although the same Sun is shining upon both, in the mirror which is polished, pure and sanctified you may behold the Sun in all its fullness, glory and power, revealing its majesty and effulgence; but in the mirror which is rusted and obscured there is no capacity for reflection, although so far as the Sun itself is concerned it is shining thereon and is neither lessened nor deprived. Therefore, our duty lies in seeking to polish the mirrors of our hearts in order that we shall become reflectors of that light and recipients of the divine bounties which may be fully revealed through them.

....the worthless and foolish have fondly imagined ...

That the Manifestations of Divine justice, the Day Springs of heavenly grace, have when they appeared amongst men always been destitute of all earthly dominion and shorn of the means of worldly ascendancy, should be attributed to this same principle of separation and distinction which animateth the Divine Purpose. Were the Eternal Essence to manifest all that is latent within Him, were He to shine in the plentitude of His glory, none would be found to question His power or repudiate His truth. Nay, all created things would be so dazzled and thunderstruck by the evidences of His light as to be reduced to utter nothingness. How, then, can the godly be differentiated under such circumstances from the froward?

This principle hath operated in each of the previous Dispensations and been abundantly demonstrated…. It is for this reason that, in every age, when a new Manifestation hath appeared and a fresh revelation of God’s transcendent power was vouchsafed unto men, they that misbelieved in Him, deluded by the appearance of the peerless and everlasting Beauty in the garb of mortal men, have failed to recognize Him. They have erred from His path and eschewed His company—the company of Him Who is the Symbol of nearness to God. They have even arisen to decimate the ranks of the faithful and to exterminate such as believed in Him.

Behold how in this Dispensation the worthless and foolish have fondly imagined that by such instruments as massacre, plunder and banishment they can extinguish the Lamp which the Hand of Divine power hath lit, or eclipse the Day Star of everlasting splendor. How utterly unaware they seem to be of the truth that such adversity is the oil that feedeth the flame of this Lamp! Such is God’s transforming power. He changeth whatsoever He willeth; He verily hath power over all things….
