Imagine a child thinking they’re a car because they spent the night in a garage. This, of course, would be comical and immature. However, the idea is similar when someone thinks they’re Christian because they were born in America or because they are the member of a particular political party. This can also be said of someone who thinks they’re a Christian because they grew up in a Christian home or because they grew up going to church. Those things don’t make someone a Christian any more than spending the night in a garage makes you a car.
