According to the creation plan, God created an ideal world that was perfect in all respects. He ordained that this ultimate world be inhabited by impeccable ideal human beings. To achieve this target, God first settled man on Earth giving him complete freedom. The present world is a selection ground for this grand project. Here, it is being observed who makes proper use of his freedom and who misuses it. At the end of human history, those who have abused their freedom will be rejected, and those who may have exercised their freedom judiciously will be selected by God and settled in Paradise.
