How great the blessedness that awaiteth the king who will arise to aid My Cause in My kingdom, who will detach himself from all else but Me! Such a king is numbered with the companions of the Crimson Ark -- the Ark which God hath prepared for the people of Bahá. All must glorify his name, must reverence his station, and aid him to unlock the cities with the keys of My Name, the omnipotent Protector of all that inhabit the visible and invisible kingdoms. Such a king is the very eye of mankind, the luminous ornament on the brow of creation, the fountainhead of blessings unto the whole world. Offer up, O people of Bahá, your substance, nay your very lives, for his assistance.
k159.
It hath been forbidden you to carry arms unless essential, and permitted you to attire yourselves in silk. The Lord hath relieved you, as a bounty on His part, of the restrictions that formerly applied to clothing and to the trim of the beard. He, verily, is the Ordainer, the Omniscient. Let there be naught in your demeanour of which sound and upright minds would disapprove, and make not yourselves the playthings of the ignorant. Well is it with him who hath adorned himself with the vesture of seemly conduct and a praiseworthy character. He is assuredly reckoned with those who aid their Lord through distinctive and outstanding deeds.
