Perhaps there is debate there, and indeed exactly that debate has happened countless times, but it does in fact say or imply that it is a "completed" work in several places. You have just pointed out how insane it is that billions of people believe they know the truth of the Bible, and yet none of them agree on any of it.

Please note again, I am not talking about the teachings of Jesus. The teachings of Jesus is not the Bible, but a small subsection of it. They may also be found in other books not included in the Nicene Convention final edit of the Bible.
