The Christian bible asserts if you believe, you will receive anything you ask for in prayer. Matthew 21:21-22. It simply doesn't work. It's an exaggerated claim at best. This theme of the power of faith is repeated throughout the Christian bible. This makes me wonder what else has been exaggerated in the Christian bible.
The Tanach does not promise magic powers to people based on whether or not they believe. That makes it a tiny bit more credible.
The Bible is against magic. Jesus was not a sorcerer like the Talmud says.
