O thou who art steadfast in the Covenant! Thy letter was received and its contents noted. Speak in accordance with the instructions written herein, and utter not even one word more: Abraham, on Him be peace, made a covenant concerning Moses and gave the glad-tidings of His coming. Moses made a covenant concerning the promised Christ, and announced the good news of His advent to the world. Christ made a covenant concerning the Paraclete and gave the tidings of His coming. The Prophet Muḥammad made a covenant concerning the Báb, and the Báb was the One promised by Muḥammad, for Muḥammad gave the tidings of His coming. The Báb made a covenant concerning the Blessed Beauty, Bahá’u’lláh, and gave the glad-tidings of His coming for the Blessed Beauty was the One promised by the Báb. Bahá’u’lláh made a covenant concerning a Promised One Who will become manifest after one thousand or thousands of years. That Manifestation is Bahá’u’lláh’s Promised One, and will appear after a thousand or thousands of years. He, moreover, with His Supreme Pen, entered into a great Covenant and Testament with all the Bahá’ís whereby they were all commanded to follow the Centre of the Covenant after His ascension, and depart not, even to a hair’s breadth, from obeying Him.
