 The reason you see so many people talk about false teachers and false prophets is not just because someone just takes joy in speaking about someone who claims to be a Christian. No, there's a dire warning. God said that he's testing people to see if they're going to follow after these false teachers who are going to eventually lead them towards a false vision or false version of God. He says that his hand will be against not only the person that gives the false prophecies and the incorrect revelation, but also the people as a matter of fact, the Bible in 1st Kings tells of a man of God who ignores what the word of God says instead listens to a prophet who is lying. The Bible still tells us that that prophet lied, but the point is he killed the man of God for not listening. There is a warning if you follow after these people, if you have these itching ears and will not listen to sound doctrine, God will still deal with you as well.
