The American believers, if they wish to carry out, in the spirit and the letter, the parting wishes of their beloved Master, must intensify their teaching work a thousandfold and extend its ramifications beyond the confines of their native land and as far as the most distant outposts of their far-flung Faith. The Tablets of the Divine Plan invest your Assembly with unique and grave responsibilities, and confer upon it privileges which your sister Assemblies might well envy and admire. The present opportunity is unutterably precious. It may not recur again. Undaunted by the perils and the uncertainties of the present hour, the American believers must press on and prosecute in its entirety the task which now confronts them. I pray for their success from the depths of my heart.
- Shoghi Effendi (From a letter dated July 28, 1936; ‘Messages to America’)
