To be ablaze “with the fire of the love of God”

O Friends! You must all be so ablaze in this day with the fire of the love of God that the heat thereof may be manifest in all your veins, your limbs and members of your body, and the peoples of the world may be ignited by this heat and turn to the horizon of the Beloved.  

- Baha’u’llah  (The Compilation of Compilations, Vol. II, Guidelines for Teaching)
