The Bahá'ís are the leaven of God, which must leaven the
lump of their nation. In direct ratio to their success will be the protection
vouchsafed, not only to them but to their country. These are the immutable laws
of God, from which there is no escape: "For unto whomsoever much is given,
of him shall be much required."
- Shoghi Effendi (From a letter dated 21 September 1957
written on behalf of Shoghi Effendi to the National Spiritual Assembly of the
United States; The Compilation of Compilations, vol. II, Guidelines for
Teaching)
