USBN 171 November 1944 p2
He feels that, although your desire to partake actively of the dangers and miseries afflicting so many millions of people today, is natural, and a noble impulse, there can be no comparison between the value of Baha'i work and any other form of service to humanity.
If the Baha'is could evaluate their work properly they would see that, whereas other forms of relief work are superficial in character, alleviating the sufferings and ills of men for a short time at best, the work they are doing is to lay the foundation of a new spiritual Order in the world founded on the Word of God, operating according to the laws He has laid down for this age. No one else can do this work except those who have fully realized the meaning of the Message of Baha'u'llah, whereas almost any courageous, sincere person can engage in relief work, etc.
The believers are building a refuge for mankind. This is their supreme, sacred task and they should devote every moment they can to this task.
