A somewhat popular notion says that religious beliefs are an "accident of birth". This idea is usually expressed in the following line of thought: "If you are a Christian, you only believe in Christianity because you were raised to believe it or perhaps because you were born in a part of the world where it is taught and practiced. But, if you had been born in the Middle East, you would probably be a Muslim. If you were born in Japan, you would probably be Buddhist or Shinto." To some, this idea seems to discredit the Christian faith. At the very least, it seems to make the idea that Christianity can be objectively true implausible. How should we understand this idea about religious beliefs? Is there any credibility to it? What does it mean for the truthfulness of Christianity?
