The Day of God
The word "Day" in such phrases as "Day of God" and "Last Day" is interpreted as meaning "Dispensation." Each of the great religion- founders has His "Day." Each is like a sun. His teachings have their dawn, their truth gradually illumines more and more the minds and hearts of the people until they attain the zenith of their influence. Then they gradually become obscured, misrepresented and corrupted, and darkness overshadows the earth until the sun of a new day arises. The day of the Supreme Manifestation of God is the Last Day, because it is a day that shall never end, and shall not be overtaken by night. His sun shall never set, but shall illumine the souls of men both in this world and in the world to come. In reality none of the spiritual suns ever set. The suns of Moses, of Christ, of Muhammad, and all the other Prophets are still shining in heaven with undiminished luster. But earthborn clouds have concealed their radiance from the people of earth. The Supreme Sun of Baha'u'llah will finally disperse these dark clouds, so that the people of all religions will rejoice in the light of all the Prophets, and with one accord worship the one God Whose light all the Prophets have mirrored forth (139:4)
