When Revelation and Deuteronomy were written, the two strongest verses against adding or changing the Bible, the Bible didn't exist. You cannot say that those verses apply to the entire Bible unless you ignore the factual history of how these things came to be. In the case of Deuteronomy, if you hold that it applies to the whole Bible, then every book after Deuteronomy except Job are null and void!

I have exposed your ignorance. By dumping even more ignorance, you do not make yourself look smarter but you make it clear that you have a shallow understanding of this topic.

Let me add Amos 3:7: Surely God will do nothing but he reveals his will to his servants the prophets. In other words, God has promised NOT to act unless he informs his prophets first, and so without prophets there can be no activity on behalf of God.

Matthew 24 does indeed warn us of false prophets and christs. How do we tell the false ones from the true ones? Why would he warn us of false prophets and christs if every prophet or christ is false? He should just say, "Don't believe in prophesy anymore, despite the past 4,000 years. I am going to shut the heavens and not reveal any more of my words to anyone, so don't even bother asking for knowledge, revelation, or information."

But indeed, he tells us to seek, ask, and knock, and he promises us that we will find, get answers, and the doors will be opened. How can we get answers except prophets are there to speak on his behalf?
