2 Peter 1:19-20

19As well as that, we have the prophets' messages from long ago. They also show us very clearly that these things are true. The prophets' words are like a light that shines in a dark place. That light continues to shine in the dark until the dawn comes. So you need to think about those messages carefully. Then the morning star will rise and it will bring light deep inside you.

20It is very important that you should understand this: The prophets' messages in the Bible did not come from their own ideas. That never happens.
