k189.
O members of parliaments throughout the world! Select ye a single language for the use of all on earth, and adopt ye likewise a common script. God, verily, maketh plain for you that which shall profit you and enable you to be independent of others. He, of a truth, is the Most Bountiful, the All-Knowing, the All-Informed. This will be the cause of unity, could ye but comprehend it, and the greatest instrument for promoting harmony and civilization, would that ye might understand! We have appointed two signs for the coming of age of the human race: the first, which is the most firm foundation, We have set down in other of Our Tablets, while the second hath been revealed in this wondrous Book.

to engage in some occupation
It is obligatory for men and women to engage in a trade or profession. Bahá'u'lláh exalts "engagement in such work" to the "rank of worship" of God. The spiritual and practical significance of this law, and the mutual responsibility of the individual and society for its implementation are explained in a letter written on behalf of Shoghi Effendi:

With reference to Bahá'u'lláh's command concerning the engagement of the believers in some sort of profession: the Teachings are most emphatic on this matter, particularly the statement in the Aqdas to this effect which makes it quite clear that idle people who lack the desire to work can have no place in the new World Order. As a corollary of this principle, Bahá'u'lláh further states that mendicity should not only be discouraged but entirely wiped out from the face of society. It is the duty of those who are in charge of the organization of society to give every individual the opportunity of acquiring the necessary talent in some kind of profession, and also the means of utilizing such a talent, both for its own sake and for the sake of earning the means of his livelihood. Every individual, no matter how handicapped and limited he may be, is under the obligation of engaging in some work or profession, for work, especially when performed in the spirit of service, is according to Bahá'u'lláh a form of worship. It has not only a utilitarian purpose, but has a value in itself, because it draws us nearer to God, and enables us to better grasp His purpose for us in this world. It is obvious, therefore, that the inheritance of wealth cannot make anyone immune from daily work.

In one of His Tablets, 'Abdu'l-Bahá states that "if a person is incapable of earning a living, is stricken by dire poverty or becometh helpless, then it is incumbent on the wealthy or the Deputies to provide him with a monthly allowance for his subsistence. . . . By 'Deputies' is meant the representatives of the people, that is to say the members of the House of Justice." (See also note 162 on mendicancy.)
In response to a question concerning whether Bahá'u'lláh's injunction requires a wife and mother, as well as her husband, to work for a livelihood, the Universal House of Justice has explained that Bahá'u'lláh's directive is for the friends to be engaged in an occupation which will profit themselves and others, and that homemaking is a highly honourable and responsible work of fundamental importance to society.
Concerning the retirement from work for individuals who have reached a certain age, Shoghi Effendi in a letter written on his behalf stated that "this is a matter on which the International House of Justice will have to legislate as there are no provisions in the Aqdas concerning it".

It hath been forbidden you to carry arms unless essential
Bahá'u'lláh confirms an injunction contained in the Bayán which makes it unlawful to carry arms, unless it is necessary to do so. With regard to circumstances under which the bearing of arms might be "essential" for an individual, 'Abdu'l-Bahá gives permission to a believer for self-protection in a dangerous environment. Shoghi Effendi in a letter written on his behalf has also indicated that, in an emergency, when there is no legal force at hand to appeal to, a Bahá'í is justified in defending his life. There are a number of other situations in which weapons are needed and can be legitimately used; for instance, in countries where people hunt for their food and clothing, and in such sports as archery, marksmanship, and fencing.
On the societal level, the principle of collective security enunciated by Bahá'u'lláh (see Gleanings from the Writings of Bahá'u'lláh, CXVII) and elaborated by Shoghi Effendi (see the Guardian's letters in The World Order of Bahá'u'lláh) does not presuppose the abolition of the use of force, but prescribes "a system in which Force is made the servant of Justice", and which provides for the existence of an international peace-keeping force that "will safeguard the organic unity of the whole commonwealth". In the Tablet of Bishárát, Bahá'u'lláh expresses the hope that "weapons of war throughout the world may be converted into instruments of reconstruction and that strife and conflict may be removed from the midst of men".
In another Tablet Bahá'u'lláh stresses the importance of fellowship with the followers of all religions; He also states that "the law of holy war hath been blotted out from the Book".

this new World Order
In the Persian Bayán, the Báb stated: "Well is it with him who fixeth his gaze upon the Order of Bahá'u'lláh, and rendereth thanks unto his Lord. For He will assuredly be made manifest. God hath indeed irrevocably ordained it in the Bayán." Shoghi Effendi identifies this "Order" with the System Bahá'u'lláh envisages in the Aqdas, in which He testifies to its revolutionizing effect on the life of humanity and reveals the laws and principles which govern its operation.
The features of the "new World Order" are delineated in the Writings of Bahá'u'lláh and 'Abdu'l-Bahá and in the letters of Shoghi Effendi and the Universal House of Justice. The institutions of the present-day Bahá'í Administrative Order, which constitute the "structural basis" of Bahá'u'lláh's World Order, will mature and evolve into the Bahá'í World Commonwealth. In this regard, Shoghi Effendi affirms that the Administrative Order "will, as its component parts, its organic institutions, begin to function with efficiency and vigour, assert its claim and demonstrate its capacity to be regarded not only as the nucleus but the very pattern of the New World Order destined to embrace in the fullness of time the whole of mankind".
For additional information on the evolution of this new World Order, see, for example, the letters of Shoghi Effendi published in The World Order of Bahá'u'lláh.

We have appointed two signs for the coming of age of the human race
The first sign of the coming of age of humanity referred to in the Writings of Bahá'u'lláh is the emergence of a science which is described as that "divine philosophy" which will include the discovery of a radical approach to the transmutation of elements. This is an indication of the splendours of the future stupendous expansion of knowledge.
Concerning the "second" sign which Bahá'u'lláh indicates to have been revealed in the Kitáb-i-Aqdas, Shoghi Effendi states that Bahá'u'lláh, ". . . in His Most Holy Book, has enjoined the selection of a single language and the adoption of a common script for all on earth to use, an injunction which, when carried out, would, as He Himself affirms in that Book, be one of the signs of the 'coming of age of the human race'".
Further insight into this process of mankind's coming of age and proceeding to maturity is provided by the following statement of Bahá'u'lláh:

One of the signs of the maturity of the world is that no one will accept to bear the weight of kingship. Kingship will remain with none willing to bear alone its weight. That day will be the day whereon wisdom will be manifested among mankind.

The coming of age of the human race has been associated by Shoghi Effendi with the unification of the whole of mankind, the establishment of a world commonwealth, and an unprecedented stimulus to "the intellectual, the moral and spiritual life of the entire human race".
