"O My brother! Sanctify thy heart, illumine thy soul, and sharpen thy sight, that thou mayest perceive the sweet accents of the Birds of Heaven and the melodies of the Doves of Holiness warbling in the Kingdom of eternity, and perchance apprehend the inner meaning of these utterances and their hidden mysteries. For otherwise, wert thou to interpret these words according to their outward meaning, thou couldst never prove the truth of the Cause of Him Who came after Jesus, nor silence the opponents, nor prevail over the contending disbelievers. For the Christian divines use this verse to prove that the Gospel shall never be abrogated and that, even if all the signs recorded in their Books were fulfilled and the Promised One appeared, He would have no recourse but to rule the people according to the ordinances of the Gospel. They contend that if He were to manifest all the signs indicated in the Books, but decree aught besides that which Jesus had decreed, they would neither acknowledge nor follow Him, so clear and self-evident is this matter in their sight."
