The Covenant of Bahá’u’lláh ...

The Covenant of Bahá’u’lláh had been instituted solely through the direct operation of His Will and purpose. The Will and Testament of ‘Abdu’l-Bahá, on the other hand, may be regarded as the offspring resulting from that mystic intercourse between Him Who had generated the forces of a God-given Faith and the One Who had been made its sole Interpreter and was recognized as its perfect Exemplar. The creative energies unleashed by the Originator of the Law of God in this age gave birth, through their impact upon the mind of Him Who had been chosen as its unerring Expounder, to that Instrument, the vast implications of which the present generation, even after the lapse of twenty-three years, is still incapable of fully apprehending. This Instrument can, if we would correctly appraise it, no more be divorced from the One Who provided the motivating impulse for its creation than from Him Who directly conceived it. The purpose of the Author of the Bahá’í Revelation had, as already observed, been so thoroughly infused into the mind of ‘Abdu’l-Bahá, and His Spirit had so profoundly impregnated His being, and their aims and motives been so completely blended, that to dissociate the doctrine laid down by the former from the supreme act associated with the mission of the latter would be tantamount to a repudiation of one of the most fundamental verities of the Faith.
