56. Verse 29 And God said, Behold, I give you every plant yielding seed which is upon the face ¹ of the whole earth, and every tree in which there is fruit, the tree producing seed will be for you for food. A celestial man takes delight in none but celestial things, and because these suit his life they are called celestial food. A spiritual man takes delight in spiritual things, and because they suit his life they are called spiritual food. The same applies to a natural man and natural things, and because they suit his life they too are called food, and are chiefly facts. Here, since the subject is the spiritual man, his spiritual food is described by representatives, that is to say, spiritual food is represented by 'the plant yielding seed' and by 'the tree in which there is fruit', which in general are called 'the tree producing seed'. His natural food is described in the next verse.

Footnotes:

The sun in the Bible represents the Lord, with its heat representing His love and its light representing His wisdom. “Daytime,” then, represents a state in which we are turned toward the Lord, receiving His love and being enlightened by His truth. And “nighttime,” obviously, represents states in which we are turned away from the Lord, left cold and blind to the truth. The most common word used for it in the New Christian theology is “obscurity.” The darkness is not absolute, of course. The light of the moon represents the understanding we can have based on facts and our own intelligence. But while the moon reflects some of the sun's light, it offers almost no heat, so this kind of understanding is a cold one, without the warmth of love. And at its darkest and coldest, night represents a state of judgment. This happens when a person -- or a church -- becomes so mired in evil and falsity that there is no light or heat. The Lord can then step in, separate the good from the evil, consign the evil to hell and begin rebuilding based on the remnant that is still good. Drastic as that sounds, it is something that we all go through repeatedly in various aspects of our loves, so that we can be rid of what is evil and let the Lord rebuild us as angels.
