When in this manner, by the ray of intelligence, one sees life, one begins to distinguish between his own will and the will of God. The kingdom of God which is in heaven then comes on earth. It does not mean that it disappears from heaven, but it only means that heaven not only remains as a kingdom of heaven, but even earth becomes a kingdom of heaven. The purpose behind all creation is that heaven may be realized on the earth. If one does not realize it on earth, he cannot realize it in heaven.
