What Is Eschatology?

I believe in the authority of scripture from the first verse of Genesis to the last verse of, of revelation. But there's one area though that oftentimes has kind of bled outside the, the, the perimeter of scriptures. And that is eschatology. There are books out on four views, three views of the book of revelation. So you've got an entire book, an entire book of the Bible is, is interpreted in four completely different ways.
