“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

December 16

O kings of Christendom! Heard ye not the saying of Jesus, the Spirit of God, “I go away, and come again unto you”? Wherefore, then, did ye fail, when He did come again unto you in the clouds of heaven, to draw nigh unto Him, that ye might behold His face, and be of them that attained His Presence?  In another passage He saith: “When He, the Spirit of Truth, is come, He will guide you into all truth.” And yet behold how, when He did bring the truth, ye refused to turn your faces towards Him, and persisted in disporting yourselves with your pastimes and fancies. Ye welcomed Him not, neither did ye seek His Presence, that ye might hear the verses of God from His own mouth, and partake of the manifold wisdom of the Almighty, the All-Glorious, the All-Wise. Ye have, by reason of your failure, hindered the breath of God from being wafted over you, and have withheld from your souls the sweetness of its fragrance. Ye continue roving with delight in the valley of your corrupt desires. By God! Ye, and all ye possess, shall pass away. Ye shall, most certainly, return to God, and shall be called to account for your doings in the presence of Him Who shall gather together the entire creation. 
- Baha’u’llah  (‘Suriy-i-Mulk [Tablet to the Kings]; ‘Summons of the Lord of Hosts’)
