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

April 18

Vie ye with each other in the service of God and of His Cause. This is indeed what profiteth you in this world, and in that which is to come. Your Lord, the God of Mercy, is the All-Informed, the All-Knowing. Grieve not at the things ye witness in this day. The day shall come whereon the tongues of the nations will proclaim: ‘The earth is God’s, the Almighty, the Single, the Incomparable, the All-Knowing!’ 
- Baha’u’llah  (Quoted by Shoghi Effendi in ‘The Advent of Divine Justice’)
