Let any one who feels the urge among the participators in this crusade, which embraces all the races, all the republics, classes and denominations of the entire Western Hemisphere, arise, and, circumstances permitting, direct in particular the attention, and win eventually the unqualified adherence, of the Negro, the Indian, the Eskimo, and Jewish races to his Faith. No more laudable and meritorious service can be rendered the Cause of God, at the present hour, than a successful effort to enhance the diversity of the members of the American Bahá'í community by swelling the ranks of the Faith through the enrolment of the members of these races. A blending of these highly differentiated elements of the human race, harmoniously interwoven into the fabric of an all-embracing Bahá'í fraternity, and assimilated through the dynamic process of a divinely-appointed Administrative Order, and contributing each its share to the enrichment and glory of Bahá'í community life, is surely an achievement the contemplation of which must warm and thrill every Bahá'í heart.
