It is our vital and most urgent duty to assure at whatever cost the safety and the unity of the Cause of God, and with harmony and concord firmly established amongst us, to arise with confidence and courage for the enlightenment of the world and the salvation of mankind. (Shoghi Effendi, from a letter dated circa March, 1923, addressed to the Baha’is of Washington DC; Star of the West, Vol. 14, April, 1923) (To read the entire letter please visit Messages to the Baha’i World)
