Baha'u'llah, meaning " The Glory of God," is the Prophet and Founder of the Bahai Faith. The main theme of Baha'u'llah's message is unity. He taught that there is only one God, that all the world's religions represent one changeless and eternal Faith of God, and that all humanity is one race, destined to live in peace and harmony.
Abdul-Baha, meaning in Arabic "Servant of the Glory," was the title assumed by Abbas Effendi (1844-1921), the eldest son and appointed successor of Baha'u'llah, the Prophet and Founder of the Bahai Faith. A prisoner since the age of nine, Abdul-Baha shared a lifetime of imprisonment and exile with his father at the hands of the Ottoman Empire. He spent his entire life in tireless service to, and promotion of, Baha'u'llah's teachings.
