As far as I know, there is no one who can explain the concrete system of Cheon Il Guk. But then is it possible to realize something without any clear vision and goal? Even if we have a clear vision and goal, it may be difficult to realize Cheon Il Guk.
Obviously, Cheon Il Guk is not the nation that can automatically be built by God’s miraculous power. The ideal of interdependence, mutual prosperity and universally shared values should be established through cooperation between God and human beings. It is wrong to think that the concrete plan for the society of Cheon Il Guk would be given by Rev. Moon or God unilaterally.
Regrettably, even inside the Unification Movement, a large number of people are reluctant to establish a concrete system for Cheon Il Guk. Their main insistence is that if the ideal world consists of “original” people (persons without fallen nature) and ideal families, the external structure will not be so important. However, it is a naive way of thinking that “original” people will do well whatever the system.
