XIII. Consider the past. How many, both high and low, have, at all times, yearningly awaited the advent of the Manifestations of God in the sanctified persons of His chosen Ones. How often have they expected His coming, how frequently have they prayed that the breeze of Divine mercy might blow, and the promised Beauty step forth from behind the veil of concealment, and be made manifest to all the world. And whensoever the portals of grace did open, and the clouds of divine bounty did rain upon mankind, and the light of the Unseen did shine above the horizon of celestial might, they all denied Him, and turned away from His face -- the face of God Himself.... (17:2)
Reflect, what could have been the motive for such deeds? What could have prompted such behavior towards the Revealers of the beauty of the All-Glorious? Whatever in days gone by hath been the cause of the denial and opposition of those people hath now led to the perversity of the people of this age. To maintain that the testimony of Providence was incomplete, that it hath therefore been the cause of the denial of the people, is but open blasphemy. How far from the grace of the All-Bountiful and from His loving providence and tender mercies it is to single out a soul from amongst all men for the guidance of His creatures, and, on one hand, to withhold from Him the full measure of His divine testimony, and, on the other, inflict severe retribution on His people for having turned away from His chosen One! Nay, the manifold bounties of the Lord of all beings have, at all times, through the Manifestations of His Divine Essence, encompassed the earth and all that dwell therein. Not for a moment hath His grace been withheld, nor have the showers of His loving-kindness ceased to rain upon mankind. Consequently, such behavior can be attributed to naught save the petty-mindedness of such souls as tread the valley of arrogance and pride, are lost in the wilds of remoteness, walk in the ways of their idle fancy, and follow the dictates of the leaders of their faith. Their chief concern is mere opposition; their sole desire is to ignore the truth. Unto every discerning observer it is evident and manifest that had these people in the days of each of the Manifestations of the Sun of Truth sanctified their eyes, their ears, and their hearts from whatever they had seen, heard, and felt, they surely would not have been deprived of beholding the beauty of God, nor strayed far from the habitations of glory. But having weighed the testimony of God by the standard of their own knowledge, gleaned from the teachings of the leaders of their faith, and found it at variance with their limited understanding, they arose to perpetrate such unseemly acts....
