He Who is your Lord, the All Merciful, cherisheth in His heart the desire of beholding the entire human race as one soul and one body.  

The well-being of mankind, its peace and security, are unattainable unless and until its unity is firmly established. 

It is not for him to pride himself who loveth his own country, but rather for him who loveth the whole world. The earth is but one country and mankind its citizens. (Baha’u’llah)

In every Dispensation, the light of Divine Guidance has been focused upon one central theme…In this wondrous Revelation, this glorious century, the foundation of the Faith of God, and the distinguishing feature of His Law, is the consciousness of the oneness of mankind. 

 Let all strive to grow in the light of the Sun of Truth, and reflecting this luminous love on all men, may their hearts become so united that they may dwell evermore in the radiance of the limitless love…When you love a member of your family or a compatriot, let it be with a ray of the Infinite Love! Let it be in God, and for God! Wherever you find the attributes of God, love that person, whether he be of your family or of another. Shed the light of a boundless love on every human being whom you meet, whether of your country, your race, your political party, or of any other nation, color or shade of political opinion. Heaven will support you while you work in this ingathering of the scattered peoples of the world beneath the shadow of the almighty tent of unity. (‘Abdu’l-Baha’)
