160 Promote ye the development of the cities of God and His countries, and glorify Him therein in the joyous accents of His well-favoured ones. In truth, the hearts of men are edified through the power of the tongue, even as houses and cities are built up by the hand and other means. We have assigned to every end a means for its accomplishment; avail yourselves thereof, and place your trust and confidence in God, the Omniscient, the All-Wise. 161 Blessed is the man that hath acknowledged his belief in God and in His signs, and recognized that "He shall not be asked of His doings". Such a recognition hath been made by God the ornament of every belief and its very foundation. Upon it must depend the acceptance of every goodly deed. Fasten your eyes upon it, that haply the whisperings of the rebellious may not cause you to slip. 162 Were He to decree as lawful the thing which from time immemorial had been forbidden, and forbid that which had, at all times, been regarded as lawful, to none is given the right to question His authority. Whoso will hesitate, though it be for less than a moment, should be regarded as a transgressor. 163 Whoso hath not recognized this sublime and fundamental verity, and hath failed to attain this most exalted station, the winds of doubt will agitate him, and the sayings of the infidels will distract his soul. He that hath acknowledged this principle will be endowed with the most perfect constancy. All honour to this all-glorious station, the remembrance of which adorneth every exalted Tablet. Such is the teaching which God bestoweth on you, a teaching that will deliver you from all manner of doubt and perplexity, and enable you to attain unto salvation in both this world and in the next. He, verily, is the Ever-Forgiving, the Most Bountiful. He it is Who hath sent forth the Messengers, and sent down the Books to proclaim "There is none other God but Me, the Almighty, the All-Wise". 164 O Land of Káf and Rá!(10) We, verily, behold thee in a state displeasing unto God, and see proceeding from thee that which is inscrutable to anyone save Him, the Omniscient, the All-Informed; and We perceive that which secretly and stealthily diffuseth from thee. With Us is the knowledge of all things, inscribed in a lucid Tablet. Sorrow not for that which hath befallen thee. Erelong will God raise up within thee men endued with mighty valour, who will magnify My Name with such constancy that neither will they be deterred by the evil suggestions of the divines, nor will they be kept back by the insinuations of the sowers of doubt. With their own eyes will they behold God, and with their own lives will they render Him victorious. These, truly, are of those who are steadfast.
