The glory of God gives life; those who see God receive life. For this reason God, who cannot be grasped, comprehended or seen, allows himself to be seen, comprehended and grasped by men, that he may give life to those who see and receive him. It is impossible to live without life, and the actualization of life comes from participation in God, while participation in God is to see God and enjoy his goodness.
Men will therefore see God if they are to live; through the vision of God they become immortal and attain to God himself. As I have said, this was shown in symbols by the prophets: God will be seen by men who hear his Spirit and are always waiting for his coming. As Moses said in the Book of Deuteronomy: On that day we shall see, for God will speak to man, and man will live.
