Consider the past.

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….
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!
