I like the story of Jonah, it exemplifies repentance. It is in the Bible, a little book of a minor prophet, but a greatness of wisdom. In the first chapter, verses 8 and 9, that expresses a kind of seal, even to suggest there is an angel standing on the sea and the land. There's a certain literal meaning, that is the experience of the prophet, and how that relates to the experiences of people, and from that are more figurative, abstract interpretations according to how anyone can identify with the story. Suppose the seven thunders are confessions, and are meant to be forgot, or that because the book of the Revelation is written down after John experienced the vision, the meanings of the seven thunders are suggested in the first chapters. To say it's sweet as honey in the mouth but it's bitter in the stomach, that could be going to a hypothetical interpretation of a candy-like, cartoonish image to a more hard-core personal realization of the same text. Proverbs is also a book of wisdom, such as verse 2 of chapter 25, that the ending of Revelation 10 could be hinting something about that, especially how it leads into Revelation 11 where the seventh angel sounded and the kingdoms of the world become the kingdoms of Christ. We can know the signs but we can't know the exact time of the return of Christ, it's almost as though if anyone tries to set the date, in the setting of it then God changes it, at which point they're stuck like Jonah on the outskirts almost disgruntled that Nineveh wasn't destroyed.
