By the righteousness of God! The tribulations We have sustained are such that any pen that recounteth them cannot but be overwhelmed with anguish. No one of them that truly believe and uphold the unity of God can bear the burden of their recital. So great have been Our sufferings that even the eyes of our enemies have wept over Us, and beyond those of every discerning person. And to all these trials have We been subjected, in spite of Our action in approaching thee, and in bidding the people to enter beneath thy shadow, that thou mightest be a stronghold unto them that believe in and uphold the unity of God.
- Baha’u’llah (Quoted by Shoghi Effendi in ‘The Promised Day Is Come’)
