Actually, there are many living an atheist fantasy life. For many it’s Halloween 24/7.
Yes, and for those living in a fantasy world without Christ, eternity will be Hell without Christ.
In fact, they are living their Hell on earth, and poisoning others, dragging them into Hell also.
Have you ever read
That Hideous Strength by C.S. Lewis? He describes a life without Christ.
It reminds me of that fictional movie on Nothingness swallowing people and everything in its path,
and the fear that movie generated. It was made for children and for people who never grew up.
That is the reason we have such sick people today. They are narcissists who never grow up.
