My mom is addicted to the WTS. I've recently brought up the many false prophecies and she calls almost every week to show me new things that the society has said about false prophets and how they are not one.
The latest was the account where King David wanted to build God a temple. He told Nathan the prophet about his idea and Nathan basically said, Well God is with you, you should do it. Then God appeared to Nathan and told him that it would be Davids son that would build the temple. So does that mean, my mom said, that Nathan was a false prophet for giving David the go ahead. I know that just about all of you would have an answer to that.
Another example the WT likes to use when accusing other prophets of false prophecy is the account of Jonah. They say that he preached that Ninevah would be destroyed by God because of their practices, but Ninevah was not destroyed at that time. They say that this is the same as what they have done in the past with their dates.
How lame are these examples! What is interesting is that they are establishing their identity as "prophets". They are the same as these other prophets, right? They have so much to answer to when standing before Gods great white throne.
