ANYONE who has not experienced heaven’s peace cannot know what the peace is that angels enjoy. As long as we are in our bodies, we cannot accept heaven’s peace, so we cannot perceive it, our perception being on the natural level. In order to perceive it, we need to be the kind of person who as to thought can be raised and taken out of the body and brought into the spirit so as to be with angels. Since I have perceived heaven’s peace in this way, I can describe it, but not in words as it really is, because human words are not adequate. Using words, I can only describe what it is like compared to that peace of mind that people have who are content in God.
There are two things at the heart of heaven, innocence and peace. We say that they are at the heart because they come straight from the Lord. From innocence comes everything good about heaven and from peace comes all the delight of that good. Everything good has its own delight, and both—the good and the delight—are matters of love. This is because what is loved is what is called good and also is perceived as delightful. It follows from this that these two inmost qualities, innocence and peace, emanate from the Lord’s divine love and move angels to their very core.
In the previous chapter on the state of innocence of heaven’s angels, it was shown that innocence is the very heart of good. Now I need to explain that peace is the very heart of the delight that comes from the goodness of innocence.
First, we need to say where peace comes from. Divine peace is within the Lord, arising from the oneness of his divine nature and the divine human nature within him. The divine quality of peace in heaven comes from the Lord, arising from his union with heaven’s angels, and specifically from the union of the good and the true within each angel. These are the sources of peace. We may therefore conclude that peace in the heavens is the divine nature intimately affecting everything good there with blessedness. So it is the source of all the joy of heaven. In its essence, it is the divine joy of the Lord’s divine love, arising from his union with heaven and with every individual there. This joy, perceived by the Lord in the angels and by the angels from the Lord, is peace. It flows down from there to provide angels with everything that is blessed and delightful and happy—what is called “heavenly joy.”
