True Parents and God need each other and humanity to achieve perfection. Perfection is realized not through individual effort but through living for the sake of others and establishing relationships of interdependence centered on love. This requires embracing the Four Position Foundation through the Holy Marriage Blessing, whereby True Parents bestow divine nature upon humanity. By living by the golden rule and principles of living for others taught by Jesus and Sun Myung Moon, each person can perfect themselves while perfecting their relationships and the world.
