People who have a religion should be glad, for not everyone has the gift of believing in heavenly things. You don’t necessarily even have to be afraid of punishment after death; purgatory, hell, and heaven are things that a lot of people can’t accept, but still a religion, it doesn’t matter which, keeps a person on the right path.
