41. So long as a person lives in the world, he cannot see what the Lord's church on earth is like, much less how it turned from good to evil in the course of time. This is because a person takes an external view while he lives in the world, and can only see what is plain to his natural man. What a church is like from a spiritual point of view, that is, from the point of view of its internals, cannot be seen on earth. But in heaven it can be seen as in bright daylight, since the angels think spiritually and also see spiritually, so that they see only what is spiritual. Moreover, all the people are gathered there who have been born in the world from the beginning of creation, as was shown above, and all are there divided into communities differing in the kinds of good of love and faith they have (see HEAVEN AND HELL 41-50). So it is that the states of a church and how it progresses are clearly to be seen by the angels in heaven. [2] Now because Revelation in its spiritual sense describes the state of the church as regards love and faith, no one can know what lies hidden within its whole narrative, unless it has been revealed to him from heaven, and he has been allowed to know the internal or spiritual sense of the Word. I can declare with assurance that all the details there, down to the individual words, contain a spiritual sense, which provides a full description of everything to do with the church as regards its spiritual state from beginning to end. Since every single word in it has some spiritual meaning, none can be omitted without changing the train of ideas in the internal sense. That is why at the end of Revelation we read:

If anyone takes away from the words of the book of this prophecy God will take away* his share in the book of life and in the holy city, and in what is written in that book. Rev. 22:19. [3] It is much the same with the books of the Old Testament Word. In those each subject and each word contains an internal or spiritual sense; so neither there can any word be taken away. That is why by the Lord's Divine providence those books have been kept intact down to the last jot from the time when they were written by the care taken by many scribes who counted even the smallest details in them. This provision by the Lord was to guard the holiness which each jot, letter and word in them possesses. * [The first edition has 'may God take away', but this is probably a printer's error; the usual form occurs in AR and this agrees with the Greek.]
