When we eat, our bodies break down the food and get from it both energy and materials for building and repairing the body. The process is similar on a symbolic level in the Bible. Food represents the desire for good and the insight that comes from that desire for good – goodness and understanding that come from the Lord. But to put them to use we have to take them in and make them our own – which is spiritual eating.

561. But what are remnants? Not only the goods and truths which one has learned from the Word of the Lord from early childhood onwards and so had imprinted in his memory, but also all resulting states, such as states of innocence from early childhood; states of love towards parents, brothers and sisters, teachers, and friends; states of charity towards the neighbour, and also of compassion on the poor and needy; in short, all states involving good and truth. These states, together with the goods and truths that have been imprinted in the memory, are called remnants, which the Lord preserves with a person and stores away in his internal man, though the person himself is not at all directly conscious of this. Here they are separated completely from the things that are the person's own, that is, evils and falsities. The Lord so preserves all of those states with the individual that not even the least of them perishes. I have been given to know this from the fact that every one of man's states from his infancy right through to extreme old age not only carries over into the next life but also reappears. Indeed those states are exactly the same as when he lived in the world. Thus not only are goods and truths in the memory carried over, but also all states of innocence and charity. And when states of evil and falsity, or wickedness and false notions, recur - for every single one of these as well, down to the smallest detail, is carried over and reappears - they are at that time moderated by the Lord through those states of innocence and charity. From all this it becomes clear that if a person possessed no remnants, he would inevitably be subject to eternal condemnation. See what has appeared already in 468.
