…it is the purity of heart, detachment, uprightness, devotion and love of the teacher that attracts the divine confirmations and enables him, however ignorant he be in this world's learning, to win the hearts of his fellowmen to the Cause of God. 
(From a letter dated 31 October 1967 written by the Universal House of Justice to all National Spiritual Assemblies; The Compilation of Compilations, vol. II, Teaching the Masses)
