The Covenant of ‘Abdu’l-Bahá was established with the believers in His Will and Testament. This Covenant continues the Covenant established by Bahá’u’lláh. “. . . Acceptance of the Master’s Will and Testament is basic in the faith of every Bahá’í and is an integral part of the Covenant which every believer undertakes to uphold when he becomes a Bahá’í.”4
‘Abdu’l-Bahá’s Will clarified and explained the workings of the Administrative Order “that Bahá’u’lláh had already created”5 in the Kitáb-i-Aqdas and other Tablets. The administration is headed by the twin institutions of the Guardianship and the Universal House of Justice. These two institutions are named by ‘Abdu’l-Bahá as His successors in His Will.
After ‘Abdu’l-Bahá, the Administrative Order is the channel through which God’s will flows to humanity to accomplish His purpose. The growth of the Administrative Order will ultimately result in the raising of Bahá’u’lláh’s new World Order.
