All the Bahá'ís, new and old alike, should devote themselves
as much as possible to teaching the Faith; they should also realize that the
atmosphere of true love and unity which they manifest within the Bahá'í
Community will directly affect the public, and be the greatest magnet for
attracting people to the Faith and confirming them. (From a letter dated 4
April 1947 written on behalf of Shoghi Effendi to the Local Spiritual Assembly
of Stuttgart, Germany; The Compilation of Compilations, vol. II, Guidelines for
Teaching)
