The Faith of Bahá'u'lláh has assimilated, by virtue of its creative, its regulative and ennobling energies, the varied races, nationalities, creeds and classes that have sought its shadow, and have pledged unswerving fealty to its cause. It has changed the hearts of its adherents, burned away their prejudices, stilled their passions, exalted their conceptions, ennobled their motives, co-ordinated their efforts, and transformed their outlook. While preserving their patriotism and safeguarding their lesser loyalties, it has made them lovers of mankind, and the determined upholders of its best and truest interests. While maintaining intact their belief in the Divine origin of their respective religions, it has enabled them to visualize the underlying purpose of these religions, to discover their merits, to recognize their sequence, their interdependence, their wholeness and unity, and to acknowledge the bond that vitally links them to itself. This universal, this transcending love which the followers of the Bahá'í Faith feel for their fellow-men, of whatever race, creed, class or nation, is neither mysterious nor can it be said to have been artificially stimulated. It is both spontaneous and genuine. They whose hearts are warmed by the energizing influence of God's creative love cherish His creatures for His sake, and recognize in every human face a sign of His reflected glory.
