331. Useful functions for the support of our bodies have to do with its nourishment, clothing, shelter, recreation and pleasure, protection, and the preservation of its state. The useful things created for physical nourishment are all the members of the plant kingdom that we eat and drink, such as fruits, grapes, seeds, vegetables, and grains. Then there are all the members of the animal kingdom that we eat, such as steers, cows, calves, deer, sheep, kids, goats, lambs, and the milk they give, as well as many kinds of bird and fish.

The useful things created for clothing our bodies also come in abundance from these two kingdoms, as do those for our shelter and for our recreation and pleasure, for our protection, and for the preservation of our state. I will not enumerate these because they are familiar, so listing them would only take up space.

There are of course many things that we do not find useful, but these extras do not prevent usefulness. In fact, they enable useful functions to continue. Then there are abuses of functions; but again, the abuse of a function does not eliminate the useful function, just as the falsification of something true does not destroy the truth except for the people who are doing the falsifying.

4. God alone--the Lord--is love itself, because he is life itself. Both we on earth and angels are life-receivers. I will be offering many illustrations of this in works on divine providence and life. Here I would say only that the Lord, who is the God of the universe, is uncreated and infinite, while we and angels are created and finite. Since the Lord is uncreated and infinite, he is that essential reality that is called Jehovah and is life itself or life in itself. No one can be created directly from the Uncreated, the Infinite, from Reality itself and Life itself, because what is divine is one and undivided. We must be created out of things created and finite, things so formed that something divine can dwell within. Since we and angels are of this nature, we are life-receivers. So if we let ourselves be misled in thought so badly that we think we are not life-receivers but are actually life, there is no way to keep us from thinking that we are God.

Our sense that we are life and our consequent belief that we are life rests on an illusion: in an instrumental cause, the presence of its principal cause is only felt as something identical to itself. The Lord himself teaches that he is life in itself in John: "As the Father has life in himself, so too he has granted the Son to have life in himself" (5:26); and again in John (11:25; 14:6) he teaches that he is life itself. Since life and love are one and the same, as we can see from the first two sections above, it follows that the Lord, being life itself, is love itself.
