August 21

I beseech Thee, [God] by them that have cut down all the idols in this Revelation through which the Most Grievous Convulsion and the Great Terror have appeared, to assist, at all times, Thy servants with the signs of Thine almighty power and the evidences of Thy transcendent and all-compelling might. Grant, then, that their hearts may be made as strong as brass, that they may remain unmoved by the overpowering might of such as have transgressed against Him Who is the Manifestation of Thine Essence and the Day-Spring of Thine invisible Self, and that they may all arise to glorify and help Thee, so that through them the ensigns of Thy triumph may be lifted up in Thy realm, and the standards of Thy Cause may be unfurled throughout Thy dominions. 
- Baha’u’llah  (‘Prayers and Meditations by Baha’u’llah’)
