"All men have been called into being for the betterment of the world."

"In brief, what is right and true in this day and acceptable before His Throne is that which was mentioned at the outset. All men have been called into being for the betterment of the world. It behoveth every soul to arise and serve his brethren for the sake of God. Should a brother of his embrace the truth, he should rejoice that the latter hath attained unto everlasting favour. Otherwise he should implore God to guide him without manifesting the least trace of animosity or ill-feeling towards him. The reins of command are in the grasp of God. He doeth what He willeth and ordaineth as He pleaseth. He, verily, is the Almighty, the All-Praised.

We beseech the one true God, magnified be His glory, to enable us to recognize Him Whose unerring wisdom pervadeth all things and that we may acknowledge His truth. For once one hath recognized Him and borne witness to His Reality, one will no longer be troubled by the idle fancies and vain imaginings of men. The divine Physician hath the pulse of mankind within His almighty grasp. At one time He may well deem fit to sever certain infected limbs, that the disease may not spread to other parts of the body. This would be the very essence of mercy and compassion, and to none is given the right to object, for He is indeed the All-Knowing, the All-Seeing."
