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)

43. This brings us to the point where we can see that divine love and wisdom in and of themselves are substance and form. They are essential reality and manifestation, and unless they were as much reality and manifestation as they are substance and form, they would be only theoretical constructs that in and of themselves are nothing.
