How to “combat effectively the ills and sicknesses of this distracted world”

With hearts united, with minds purified and with a determination never to waver or surrender, let us step into the arena of service and armed with the sword of utterance and teaching combat effectively the ills and sicknesses of this distracted world.

We need not feel depressed or overwhelmed with the magnitude of the task for the mighty combatants whom the hands of the Master have raised in every part of the globe shall come to our aid and the Hosts of the Unseen shall reinforce our numbers till the Spirit of Love and Peace even as foretold in the Holy Writ of Baha'u'llah will have filled the world.
