38. The internal man is what is called the spiritual man, because he is in heaven's light, which is spiritual light; and the external man is what is called the natural man, because he is in the world's light, which is natural light. A person whose internal is in heaven's light and whose external is in the world's light is a spiritual man in both respects; but one whose internal is not in heaven's light, but only in the world's light shared with the external, is a natural man in both respects. A spiritual man is called in the Word living, and a natural man is called dead.
