Then I think we have a large problem.....the Bible as we have it today, as I'm sure you know, is not what it was when it was first written. A lot of things were left out of the canon when the book was compiled, so the people who gave us "the Bible" took things away from it. In order to make up the book, they had to add things to it as well. God himself didn't pick up a pen and write, he had people do it for him. So, I suppose none of the gospel writers got that memo.
And, if people could create, take away and add things to the book at that time, when and why did that change? Are you saying that God doesn't speak to people today? I don't think as a book, it can never be complete unless we assume god has nothing more to say. Of course he has more to say, some people just stopped listening.
