[218] In this Day nothing is so important as service. Did not ‘Abdu’l-Bahá voluntarily call Himself the ‘Servant’ of Bahá, manifesting also in His life the perfections of servitude to God and man?
We, wishing to follow the commands left by Bahá’u’lláh, spread and lived by ‘Abdu’l-Bahá, we can take no greater step toward the Heavenly Kingdom—can give no greater joy to the present beloved Guardian of the Cause, Shoghi Effendi—than that of loving service to all mankind.
