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

May 4

O followers of the Son!  We have once again sent John unto you, and He, verily, hath cried out in the wilderness of the Bayán:  O peoples of the world!  Cleanse your eyes!  The Day whereon ye can behold the Promised One and attain unto Him hath drawn nigh!  O followers of the Gospel!  Prepare the way!  The Day of the advent of the Glorious Lord is at hand!  Make ready to enter the Kingdom.  Thus hath it been ordained by God, He Who causeth the dawn to break. 
- Baha'u'llah  (Tablet to Pope Pius IX, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
