525. Many people who arrive in the other life from the Christian world bring with them a faith that they are going to be saved out of straight mercy, because they plead for it. When they are examined, though, it turns out that they have believed that getting into heaven was simply a matter of being let in, and that people who had been admitted were in heavenly joy. They have had no notion of what heaven is or what heavenly joy is. So they are told that the Lord does not deny heaven to anyone. They can be let in if they wish and even stay there. Some who wanted to were actually let in; but at the very threshold, at the touch of heaven's warmth (that is, of the love angels are engaged in) and the inflow of heaven's light (which is divine truth), they were seized with such pain in the heart that they felt themselves in the torments of hell rather than in the joys of heaven. Struck by this, they plunged down headlong. In this way they were taught by firsthand experience that no one can enter heaven out of straight mercy.

The reason it appears indescribable and incomprehensible is that is in a higher degree.
