458. These points clarify where the connection between loving God and loving our neighbor comes from and what it is like: God's love for people flows into us; when we receive that love and cooperate with it, it becomes love for our neighbor.

Briefly put, the connection accords with the following saying of the Lord's:

On that day you will recognize that I am in my Father and you are in me and I am in you. (John 14:20)

And this saying:

The people who love me are those who have my commandments and do them. I will love these people, manifest myself to them, and make a home with them. (John 14:21-23)

All the Lord's commandments relate to loving our neighbor. In summary form, they involve not doing evil to our neighbors, and instead doing them good. According to the Lord's words just quoted, people like this love God and God loves them.

Because love for God and love for our neighbor are connected in this way, John says:

Those who keep the commandments of Jesus Christ live in him, and he lives in them. If any say, "I love God in every way" but hate their brothers and sisters, they are liars. If they do not love their brothers and sisters, whom they see, how can they love God whom they do not see? This commandment we have from him: that people who love God also love their brothers and sisters. (1 John 3:24; 4:20-21)

3646. So far as influx and correspondences are concerned, it is similar with animals as with men. That is to say, with an animal there is an influx from the spiritual world and an afflux from the natural world which hold it together and give it life. But the actual operation of that influx and afflux varies according to the forms which animals' souls take and consequently which their bodies take. It is like the light of the world which flows into varying objects on earth to the same degree and in the same way yet acts in differing ways within differing forms. In some it produces beautiful colours, in others horrid colours. Thus when spiritual light flows into the souls of animals its reception is completely different, and the effect it therefore has on the activity of their souls is different from its reception and the effect it has when it flows into the souls of human beings.

[2] For the souls of human beings exist on a higher level and in a more perfect state, and are such that they are able to look upwards, and so to heaven and the Lord. Consequently the Lord is able to join them to Himself and grant them eternal life. But the souls of animals are such that they cannot do other than look downwards, thus merely to earthly things, and so can be joined only to these. This is also why they perish together with the body. It is their ends in view that show what the life possessed by man is like and what that possessed by a beast is like. Man is able to have spiritual and celestial ends in view, and to see, acknowledge, and believe them, and to have an affection for them. But beasts can have none but natural ends in view. Thus man is able to dwell in the Divine sphere of ends and purposes which exist in heaven and which constitute heaven, whereas beasts can dwell in no other sphere than that of ends and purposes which exist on earth. Ends are nothing else than loves, for the things which people love they have as an end in view.

[3] The reason why most people do not know how to distinguish their own life from that of beasts is that the two are externally alike. Both are interested in and set their hearts solely on earthly, bodily, and worldly objects. Such people also believe that their life is similar to the life which beasts possess and that like these they are going to become nothing at all when they die. For what spiritual and celestial things may be they do not know because they are not interested in them. From this comes the insanity of our own times of people comparing themselves to animals and not recognizing any internal distinction. But anyone who believes in the existence of celestial and spiritual things, that is, who allows spiritual light to flow in and influence him, sees quite the reverse, and also sees the extent to which he is superior to animals. The life of animals however will in the Lord's Divine mercy be dealt with as a separate subject.
