Actually, leading scholars who believe in hell will tell you Luke 16 actually has nothing to do with hell. It can't possibly, b/c it takes place before the Day of Judgment. As for Revelation, if you want to take the Lake of Fire literally, you'll also have to agree that Jesus is literally a lamb, b/c that is how he is portrayed in Revelation 14. Chance are you don't think Jesus was literally a lamb. You realize the author is using figurative language, which means you're interpreting, which means you are imposing your own reading on the text. So don't be surprised when others do the same--or when their reading disagrees with yours.
