I accept Hosea and Isaiah as prophets because I've had a vision of God and this has caused me to do things I otherwise wouldn't have. I just feel that when a person is contacted by God it can lead to bizarre behavior. For me, it freaked me out so much that I just basically lost my shit and couldn't keep it together. So I kinda expect that if others have been contacted by God it would have a similar effect on them.

The rest of the prophets really aren't necessary is what it comes down to. I dismiss Jeremiah as well because of some of his Messianic prophecies not coming to fruition. Namely he said the Messiah (my servant david) would come when there was still a "house of Israel" and a "house of Judah." That stopped being a reality 2500 years ago. Why did he say that? He thought the Messiah that Isaiah previously wrote about was going to come soon. However, that clearly didn't happen. So I reject him too.

And like I said, none of the other books are really necessary. I suppose Joel is because it talks about the "Day of the LORD" which has now been brought to be the "judgment day" that Christians and Muslims believe in. However, that doesn't really fit with what Isaiah says about the end of days. And you know I believe in Isaiah.

I think you have thrown the baby out with the bathwater. It is at least possible that some of these are true prophetic works. It would be like finding something wrong with a couple of books on evolution and throwing all of them out. People wanted to be prophets. Maybe they even had the best of intentions. They just weren't prophets.

And there was really no way 2000 years ago when the Bible was canonized that you could weed them out very well. We have 1000's of years of history, change in the world, and knowledge to know better than those men did. Most people believe in it because they believe God orchestrated the canonization of the Bible. Why believe that? Is there any proof God had anything to do with it? No. And we know that there are plenty of books that didn't make it in. I just go a little further than everyone else.
