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 turned 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 become the world of Angels. 
- ‘Abdu’l-Baha  (From a Tablet, Star of the West, vol. 2, no. 1, March 21, 1911)
