The truth is manifest, the kingdom of utterance is resplendent, and the Day of God is clearly revealed! And yet souls who would, wholly for the sake of God, awaken the people and guide them to the True One are as scarce as the philosopher’s stone!

How many the lands that remained untilled and uncultivated; and how many the lands that were tilled and cultivated, and yet remained without water; and how many the lands which, when the harvest time arrived, no harvester came forth to reap! However, through the wonders of God’s favour and the revelations of His loving-kindness, We cherish the hope that souls may appear who are the embodiments of heavenly virtue and who will occupy themselves with teaching the Cause of God and training all that dwell on earth.

—Bahá’u’lláh
