There can be no doubt whatever

 

There can be no doubt whatever that, in consequence of the efforts which every man may consciously exert and as a result of the exertion of his own spiritual faculties, this mirror can be so cleansed from the dross of earthly defilements and purged from satanic fancies as to be able to draw nigh unto the meads of eternal holiness and attain the courts of everlasting fellowship. In pursuance, however, of the principle that for every thing a time hath been fixed, and for every fruit a season hath been ordained, the latent energies of such a bounty can best be released, and the vernal glory of such a gift can only be manifested, in the Days of God.
Invested though each day may be with its pre-ordained share of God’s wondrous grace, the Days immediately associated with the Manifestation of God possess a unique distinction and occupy a station which no mind can ever comprehend. Such is the virtue infused into them that if the hearts of all that dwell in the heavens and the earth were, in those days of everlasting delight, to be brought face to face with that Day Star of unfading glory and attuned to His Will, each would find itself exalted above all earthly things, radiant with His light, and sanctified through His grace. All hail to this grace which no blessing, however great, can excel, and all honor to such a loving-kindness the like of which the eye of creation hath not seen! Exalted is He above that which they attribute unto Him or recount about Him!
