Sorry, TI. People are not raised to be Christians. The maybe raised in a Christian home, but they become Christians by accepting Jesus Christ as their personal Savior.
That maybe what you meant, I could not tell from your post.
Jesus made the only way to Heaven. The choice is ours, unfortunately people do not always choose wisely.
Not “raised to be Christian” specifically, but the upbringing helps. “Raised to not be Christian” certainly applies for a lot of other cultures.
