I’m not familiar with the Bible’s terms, but it would appear that I do not.
This is a perfect illustration of thought circumscribed by materialism.
Of course you do not believe in anything of a uniquely spiritual nature. Your weltenschauung (understanding of reality) is inadequate to the task.
I challenge you to begin reading the Bible. You will have your world view expanded again and again if you take this challenge seriously. Or, perhaps, you do not want to be enlightened by the spiritual. Your choice.
