92. In the preceding pages it has been told what is meant by the "seven churches" and by the "angels" thereof; namely, by the "seven churches" all who are in truths from good, and by the "seven angels" all in heaven that correspond to them (see n. 20, 90); and since heaven and the church make one by correspondence, it is said in what follows, "To the angel of the church, write," and not, Write to the church. It is so said for this reason also, that there must be correspondence in order that the church may be a church with man; if there were no correspondence, there would be no communication of heaven, thus no heaven, with man; and if heaven were not with him neither would the church be with him. (See The Doctrine of the New Jerusalem, n. 241-248. What the correspondence of the man of the church with heaven is, cannot be told in a few words, but whoever desires may be taught what it is in what is said and shown in the work on Heaven and Hell, n. 87-115 and 291-310.) In a word, there is correspondence when man has becomes spiritual, and man becomes spiritual when he acknowledges the Divine and especially the Lord, and loves to live according to the precepts in the Word, for when he does this he is conjoined with heaven; and then the spiritual corresponds with the natural which is with him. I am aware that to many these things may seem to exceed their comprehension; but the reason is that it is not the delight of their love to know them; if it were the delight of their love, not only would they perceive them clearly, but they would also be eager to, know much more of such things; for a man desires what he loves, and what he loves is his delight; moreover, whatever is loved enters both with joy and with light into the idea of the mind.
