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

December 30

We, verily, see amongst you him who taketh hold of the Book of God and citeth from it proofs and arguments wherewith to repudiate his Lord, even as the followers of every other Faith sought reasons in their Holy Books for refuting Him Who is the Help in Peril, the Self-Subsisting. Say: God, the True One, is My witness that neither the Scriptures of the world, nor all the books and writings in existence, shall, in this Day, avail you aught without this, the Living Book, Who proclaimeth in the midmost heart of creation: “Verily, there is none other God but Me, the All-Knowing, the All-Wise.” 
- Baha’u’llah  (‘The Kitab-i-Aqdas’)
