AE 342c - spiritual or natural sight

I saw a new heaven and a new earth; for the first heaven and the first earth were passed away. (Revelation 21:1)
...it has been understood heretofore that the visible heaven and the habitable earth were to perish, and that a new heaven and a new earth were to arise. That "heaven" here means the heaven where angels are, and "earth" means the church where men are, and that these are to become new, those who think merely naturally and sensually are not willing to admit, and therefore do not understand; for they do not suffer their mind to be elevated out of the natural light into spiritual light.... For every one has an internal and an external man, or a spiritual and a natural; the internal or spiritual man sees from the light of heaven, but the external or natural man sees from the light of the world.
