How “the world of Satan becomes the world of Angels”

I desire for you all that you will have this great assistance and partake of this great bounty, and that in spirit and heart you will strive and endeavor until the world of war become the world of peace; the world of darkness the world of light; satanic conduct be turned into heavenly behavior; the ruined places become built up; the sword be turn into the olive branch; the flash of hatred become the flame of the love of God and the noise of the gun the voice of the Kingdom; the soldiers of death the soldiers of life; all the nations of the world one nation; all races as one race; and all national anthems harmonized into one melody.

Then this material realm will be Paradise, the earth Heaven, and the world of Satan becomes the world of Angels. 

- ‘Abdu’l-Baha  (‘Tablets of ‘Abdu’l-Baha’, vol. 1)

Fear of God is “leader and commander of” “the hosts of praiseworthy deeds and upright character”

In this Revelation the hosts that can render it victorious are the hosts of praiseworthy deeds and upright character. The leader and commander of these hosts hath ever been the fear of God, a fear that encompasseth all things and reigneth over all things. 

- Baha'u'llah  ('Tablets of Baha'u'llah revealed after the Kitab-i-Aqdas')

“fragrance of sanctity” and “spotless chastity”

He is My true follower who, if he come to a valley of pure gold, will pass straight through it aloof as a cloud, and will neither turn back, nor pause. Such a man is, assuredly, of Me. From his garment the Concourse on high can inhale the fragrance of sanctity.... And if he met the fairest and most comely of women, he would not feel his heart seduced by the least shadow of desire for her beauty. Such an one, indeed, is the creation of spotless chastity. Thus instructeth you the Pen of the Ancient of Days, as bidden by your Lord, the Almighty, the All-Bountiful.

Difference between the “ material civilization now prevailing, and the divine civilization which will be one of the benefits to derive from the House of Justice”

As to the difference between that material civilization now prevailing, and the divine civilization which will be one of the benefits to derive from the House of Justice, it is this: material civilization, through the power of punitive and retaliatory laws, restraineth the people from criminal acts; and notwithstanding this, while laws to retaliate against and punish a man are continually proliferating, as ye can see, no laws exist to reward him. In all the cities of Europe and America, vast buildings have been erected to serve as jails for the criminals.

Divine civilization, however, so traineth every member of society that no one, with the exception of a negligible few, will undertake to commit a crime. There is thus a great difference between the prevention of crime through measures that are violent and retaliatory, and so training the people, and enlightening them, and spiritualizing them, that without any fear of punishment or vengeance to come, they will shun all criminal acts. They will, indeed, look upon the very commission of a crime as a great disgrace and in itself the harshest of punishments. They will become enamoured of human perfections, and will consecrate their lives to whatever will bring light to the world and will further those qualities which are acceptable at the Holy Threshold of God.

See then how wide is the difference between material civilization and divine. With force and punishments, material civilization seeketh to restrain the people from mischief, from inflicting harm on society and committing crimes. But in a divine civilization, the individual is so conditioned that with no fear of punishment, he shunneth the perpetration of crimes, seeth the crime itself as the severest of torments, and with alacrity and joy, setteth himself to acquiring the virtues of humankind, to furthering human progress, and to spreading light across the world.

Not to challenge or criticize another person’s view concerning his/her religion, instead “present the Bahá'í concepts, as expressed by 'Abdu'l-Bahá”

The House of Justice feels that in discussion with ... you should not challenge this point, nor should you enter into criticisms of the often ruthless manner in which the followers of new religions have suppressed the old ways. It is suggested that, instead, you present the Bahá'í concepts, as expressed by 'Abdu'l-Bahá, namely that the fountainhead of all religions is to be found in God through the Teachings of His Prophets, and that all peoples have drunk at this ocean of divine Revelation; that sterile traditions and blind imitations accumulating over the centuries, exacerbated by the barriers of geography, have caused hatred and conflict where there should have been love and collaboration. These distortions have also given rise to the cruel and debased customs which are to be found in some religions. It is the Bahá'í belief that each human soul has the duty to God and the inborn capacity to seek out truth for himself. Those who do this sincerely will ultimately find themselves united, for there is only one God and Source of Truth. The Bahá'í attitude to earlier religions, therefore, is not that they are false or "heathen", but that, at root, they are all true and that these fundamental truths still persist within them. Bahá'ís encourage Indians in South America, for example, to see and reverence the profound spiritual truths which are to be found in both their pre-Christian religions and in the Catholicism which, in later centuries, has to varying degrees supplanted or overlaid their archaic faiths. Through the Bahá'í teachings, the inner conflict which many still feel between their ancient religions and Christianity is resolved and, at the same time, they are enabled to understand their spiritual unity with the peoples of other continents, such as Buddhists, Hindus and Muslims with whom they will undoubtedly come into contact with increasing frequency.

Circumstances under which Prophet Muhammad “was forced to take up arms”

It was among such tribes [of Arabia] that Muhammad was sent forth. For thirteen years He suffered at their hands every conceivable tribulation, till at last He fled the city and emigrated to Medina. And yet, far from desisting, these people joined forces, raised an army, and attacked with the aim of exterminating every man, woman, and child among His followers. It was under such circumstances and against such people that Muhammad was forced to take up arms. This is the plain truth—we are not prompted by fanatical attachment, nor do we blindly seek to defend, but we examine and relate matters with fairness. You should likewise consider in fairness the following: If Christ Himself had been placed in similar circumstances and among such lawless and barbarous tribes; if for thirteen years He and His disciples had patiently endured every manner of cruelty at their hands; if they were forced through this oppression to forsake their homeland and take to the wilderness; and if these lawless tribes still persisted in pursuing them with the aim of slaughtering the men, pillaging their property, and seizing their women and children—how would Christ have dealt with them? If this oppression had been directed towards Him alone, He would have forgiven them, and such an act of forgiveness would have been most acceptable and praiseworthy; but had He seen that cruel and bloodthirsty murderers were intent upon killing, pillaging, and tormenting a number of defenceless souls and taking captive the women and children, it is certain that He would have defended the oppressed and stayed the hand of the oppressors.

What objection, then, can be directed against Muhammad? Is it this, that He did not, with His followers and their women and children, place himself at the mercy of these lawless tribes? Moreover, to free these tribes from their bloodthirstiness was the greatest gift, and to curb and restrain them was pure bounty. It is like a man who holds in his hand a cup of poison and who is about to drink it. A loving friend would certainly shatter the cup and restrain the drinker. If Christ had been placed in similar circumstances, He would have undoubtedly delivered, through an all-conquering power, those men, women, and children from the claws of such ravenous wolves.

“Each creature is the recipient of some portion” of the rays of “the Essence of Divinity, the Sun of Truth”

… the Essence of Divinity, the Sun of Truth, shines forth upon all horizons and is spreading its rays upon all things. Each creature is the recipient of some portion of that power, and man, who contains the perfection of the mineral, the vegetable and animal, as well as his own distinctive qualities, has become the noblest of created beings. It stands written that he is made in the Image of God. Mysteries that were hidden he discovers; and secrets that were concealed he brings into the light. By Science and by Art he brings hidden powers into the region of the visible world. Man perceives the hidden law in created things and co-operates with it. 

- ‘Abdu’l-Baha  (From a talk in London, England, September 17, 1911; “‘Abdu’l-Baha in London”)

“the fruit of every science…”

How vast the number of people who are well versed in every science, yet it is their adherence to the holy Word of God which will determine their faith, inasmuch as the fruit of every science is none other than the knowledge of divine precepts and submission unto His good-pleasure. 

- The Báb  (Selections from the Writings of the Báb)

Spiritual versus physical wine

The Mystic Wine of the one true God hath a different intoxication and imparteth another exhilaration. The one diminisheth the intelligence of man, the other increaseth it. The one leadeth to perdition, the other bestoweth life. 

- Baha’u’llah  (From a Tablet; The Compilation of Compilations, vol. II, Prohibition on Drinking Alcohol)

Growth of the Faith and opposition by Christian clergy

Thou hadst written concerning the growth in stature of the Cause of God in thy country [Germany]. There is no doubt that the Faith of God will progress from day to day in that land, for it will be aided by the strengthening power of the Holy Spirit and the confirmation of the Word of God. Nor is there any doubt that members of the Christian clergy will rise up against it in implacable hostility, wishing to injure and oppress you, and seeking to assail you with doubts; for the spread of the Cause of God will lead to the waning of their fortunes--as the fortunes of the Pharisees had waned before them--and entail the loss of the dignity and standing that they now enjoy amongst men.

Reflect upon the time of Jesus and the deeds wrought by the Jewish divines and Pharisees. Such deeds will, in this day, be repeated at the hands of these Christian clergymen. Be not perturbed, however; be firm and constant, for it is certain that a company of souls shall, with infinite love, arise to enter into the Kingdom of God. These souls shall recompense you for the vexations, the humiliations, and disdain to which you are subjected by the clergy: to the injuries inflicted by these latter they shall respond with acts of kindness, until eventually, as the experience of former times hath shown, the children of the Kingdom shall gain the ascendancy, and victory shall be theirs. Rest ye confident of this.
