These are the days for rendering the divine Cause victorious and effective aid! The victory of God's Faith is dependent upon teaching; and teaching is conditional upon righteous actions and goodly deeds and conduct. The foundation-stone of a life lived in the way of God is the pursuit of moral excellence and the acquisition of a character endowed with qualities that are well-pleasing in His sight. The Bahá'ís should adorn themselves with this holy raiment; with this mighty sword they should conquer the citadels of men's hearts. 
(Shoghi Effendi, from a letter dated 8 December 1923 to a Bahá'í community - translated from the Persian; The Compilation of Compilations, vol. I, Trustworthiness: A Cardinal Bahá'í Virtue)
