“Say: O concourse of the heedless! I swear by God! The promised day is come, the day when tormenting trials will have surged above your heads, and beneath your feet, saying: ‘Taste ye what your hands have wrought!’” “The time for the destruction of the world and its people hath arrived. He Who is the Pre-Existent is come, that He may bestow everlasting life, and grant eternal preservation, and confer that which is conducive to true living.” “The day is approaching when its [civilization’s] flame will devour the cities, when the Tongue of Grandeur will proclaim: ‘The Kingdom is God’s, the Almighty, the All-Praised!’”
- Baha’u’llah (Quoted by Shoghi Effendi in ‘The Advent of Divine Justice’)
