The Bible also proves that Christians are the only people on earth who have a right to call themselves "Jews," though obviously we don't want the name anymore. The bible also proves that Israel isn't a place or an ethnicity, but an idea that constitutes the body of Christ - thus, **_we_** are Israel. The Bible also warns against false prophets, saying they will preach in His name but will lead people astray. And the Bible even warns against literalist interpretations of the scriptures.
This man is a false prophet. His god is not God - he is a servant of Satan. Obviously. Any real Christian can read his Bible and use his own brain, and rely on the spirit to inform him where he's uncertain. Thus, any real Christian knows that that is a false prophet. Speak up, don't let your people fall under his dark spell.
