The prayer that the Guardian requested all believers to offer on his behalf

Shoghi Effendi, 1921

I cherish the hope that, from now on the Beloved may bestow upon me all the strength and vigour that will enable me to pursue over a long and unbroken period of strenuous labour the supreme task of achieving, in collaboration with the friends in every land, the speedy triumph of the Cause of Bahá’u’lláh. This is the prayer I earnestly request all my fellow brethren and sisters in the Faith to offer on my behalf.
