O peoples of the world! Forsake all evil, hold fast that which is good. Strive to be shining examples unto all mankind, and true reminders of the virtues of God amidst men. He that riseth to serve My Cause should manifest My wisdom, and bend every effort to banish ignorance from the earth.
- Baha’u’llah ('Lawh-i-Hikmat', The Baha’i Year Book 1924-1925)
