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

December 10

He it is Who is established upon this luminous Throne.

Proclaim unto the celestial Concourse, O Pen of effulgent glory, that lo, the veil of concealment hath been rent asunder and the Beauty of the Lord hath been revealed from this Scene of transcendent glory with such radiance as to cause the luminaries of His command to shine above the dayspring of His almighty Name. All hail then to this, the Festival of the Lord, that hath dawned above a horizon of surpassing grace!

This is a festival wherein all things have been adorned with the vesture of the names of God, and wherein His bounty hath compassed all things from first to last. All hail then to this, the Festival of the Lord, that hath shone above a dayspring of resplendent holiness! 
- Baha’u’llah  (‘Days of Remembrance’)
