O morning star, son of the dawn!
You have been cast down to the earth,
you who once laid low the nations!

16"I, Jesus, have sent my angel to give you[a] this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star."
It is quite clear to me that the passage that relates to the entity the Christians call Lucifer/The Devil is indeed the same thing as Jesus. There are some confusing things in the Bible, but eventually you can understand them and realize that the Christians have secretly been worshiping Lucifer by renaming him Jesus.
Weird...
