Every individual believer—man, woman, youth and child—is summoned to this field of action; for it is on the initiative, the resolute will of the individual to teach and to serve, that the success of the entire community depends. Well-grounded in the mighty Covenant of Bahá’u’lláh, sustained by daily prayer and reading of the Holy Word, strengthened by a continual striving to obtain a deeper understanding of the divine Teachings, illumined by a constant endeavor to relate these Teachings to current issues, nourished by observance of the laws and principles of His wondrous World Order, every individual can attain increasing measures of success in teaching. In sum, the ultimate triumph of the Cause is assured by that “one thing and only one thing” so poignantly emphasized by Shoghi Effendi, namely, “the extent to which our own inner life and private character mirror forth in their manifold aspects the splendor of those eternal principles proclaimed by Bahá’u’lláh.”
