The vision of a peaceful world

Bahá'u'lláh wrote in the 19th century: "Let your vision be world embracing, rather than confined to your own selves."
How might we participate in this vision, and what might it enable us to do?
Here from the head of Worldwide Federation of UN Associations (WFUNA):

"Global citizenship has been an ongoing theme for the WFUNA in the past year. Every individual who is a part of our network is a Global Citizen. We are all committed to the ideals of the United Nations, express an acute interest in today's global issues, and are working towards a world of peaceful cooperation, sustainable development, and human rights for all people."

    God's greatest gift to man is that of intellect, or understanding...
    Possessing this gift, he...can frequently...reach out with prophetic vision.
    God gave this power to man that it might be used for the advancement of civilization, for the good of humanity, to increase love and concord and peace. ... Christ has commanded that [we] should love [our fellow-creatures as ourselves]!
    I hope that you will use your understanding to promote the unity and tranquillity of mankind, to give enlightenment and civilization to the people, to produce love in all around you, and to bring about the universal peace. ...
   [A]cquire more and more knowledge. Assuredly one may learn to the end of one's life! Use your knowledge always for the benefit of others; so may war cease on the face of this beautiful earth, and a glorious edifice of peace and concord be raised.

    If you desire with all your heart, friendship with every race on earth, your thought, spiritual and positive, will spread; it will become the desire of others, growing stronger and stronger, until it reaches the minds of all men.
    Do not despair! Work steadily. Sincerity and love will conquer hate. How many seemingly impossible events are coming to pass in these days! Set your faces steadily towards the Light of the World. ...

    By the fire of the Love of God the veil is burnt which separates us from the Heavenly Realities, and with clear vision we are enabled to struggle onward and upward, ever progressing in the paths of virtue and holiness, and becoming the means of light to the world.
