The Bible is God's revelation of himself to mankind, and the problem with that idea is that the same God who created and preserved the universe promised that the word of God would endure. Jesus didn't correct the Old Testament, he reinforced the truth of it (while simultaneously fulfilling some of the parts, which is one reason the church has different goals and practices than the nation of Israel). If you search out the Old Testament, there was provision made for the stranger (I'm trying to explain that God didn't JUST work with the Jews, but they allowed themselves to be the nation that would bring forth the Messiah who would save the whole world, and, as such, they received blessings that go along with that). At the same time, we have more historical proof that the Bible is accurate than any other ancient writing. If you want a good resource to look at and study that uses logical deduction, I highly recommend J. Warner Wallace's Cold Case Christianity. It focuses on the New Testament, but if you come to the conclusion that that is accurate, then you need to understand that Jesus Christ doesn't back up your idea. Sorry for the long winded answer, and have a good day!
