We will have ONE WORLD
Oneness of God = There is just one All Powerful Creator.
Oneness of Religion = God has taught us One Spiritual Truth, down through the ages through Prophets and Messengers
it is mankind that has separated these religions into different names; Oneness of Mankind = The time has come for Unity among all mankind. Baha'u'llah said: Ye are all the leaves of one tree and the drops of one ocean.
