Why was it necessary to create Adam and Eve with dual characteristics? To become just like the invisible God, they must achieve mind-body unity within their lifetime – by the time they depart for the other world. Otherwise, when they appear in the other world, they cannot become one with God. God created Adam and Eve with a dual nature so that the parents having substantial kingship in the physical world could become one with God as the invisible parent and manifest a substantial kingship in the eternal heavenly world. Even God has no way of relating to the world without connecting with Adam and Eve. God must make a relationship with Adam and Eve in order to make a relationship with their sons and daughters.
