The first sign of faith is love

The first sign of faith is love. The message of the holy, divine Manifestations is love; the phenomena of creation are based upon love; the radiance of the world is due to love; the well-being and happiness of the world depend upon it. Therefore, I admonish you that you must strive throughout the human world to diffuse the light of love. The people of this world are thinking of warfare; you must be peacemakers. The nations are self-centered; you must be thoughtful of others rather than yourselves. They are neglectful; you must be mindful. They are asleep; you should be awake and alert. May each one of you be as a shining star in the horizon of eternal glory. This is my wish for you and my highest hope.
