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.

3168. 'And they ate and drank' means making one's own the good and truth introduced in this way. This is clear from the meaning of 'eating' as being communicated and joined together, thus being made one's own, dealt with in 2187, 2343, and more specifically (since 'eating' has reference to bread and 'bread' means good, 276, 680, 2165, 2177, 2187) making good one's own; and from the meaning of 'drinking' as being communicated and joined together, thus being made one's own, dealt with in 3089, and more specifically (since 'drinking' has reference to wine and 'wine' means truth, 1071, 1798) making truth one's own. The situation is as stated above in 3167, namely that when truth is introduced into good in the rational, more so when it is joined to it, the good and truth of the spiritual man, that is, spiritual things, become made over to the natural as its own.
