Cheon Seong Gyeong, Book 5: Earthly Life and the Spirit World, Chapter 1, Section 1.7
You may not know of the reality of the spirit world, but I enjoy the special benefit from God of having a clear insight into that unknown world.
Digging into the root of that world, I found its principles to be quite simple. In the spirit world only those who lived altruistically in line with God's universal principles can enter the higher realms. The world structured along those lines is the ideal heavenly kingdom.
That place is the original homeland that humankind must seek. Today, although we are exiles from our original homeland and live a fallen life, we are destined to return there. God had to create a path for this in the course of history because we could not do so by our own efforts.
This is why God raised up many religions according to the cultural background, customs and traditions of certain peoples, and has thus guided them. Religions were established as the training grounds for guiding people in that way. They are the training grounds to cultivate the people who are qualified to return to the original homeland. God is leading humanity [us] toward a unified world of religion that can progress upward onto higher ground according to the cultural backgrounds of east and west and all corners of the world.
What does religion which guides people to the original homeland, centrally teach? It is to live for the sake of others. As highly developed religions tend to emphasize this principle, they teach us to be gentle and meek, to stand in a position to elevate others and live for their sake, and to serve them sacrificially. All this serves to instill discipline in us so we will be able to abide by the laws of the Kingdom of Heaven. (78-115, 1975.5.6)
