One’s relationship to Baha’u’llah

Great is thy blessedness inasmuch as thou hast been faithful to the Covenant of God and His Testament... Dedicate thyself to the service of the Cause of thy Lord, cherish His remembrance in thy heart and celebrate His praise in such wise that every wayward and heedless soul may thereby be roused from slumber. 

- Baha’u’llah  (‘Tablets of Bahá'u'lláh Revealed after the Kitáb-i-Aqdas’; The Compilation of Compilations vol. I, The Covenant)
