Christianity teaches that sin is so destructive it shatters souls and destroys worlds. It’s like a cancer that slowly consumes everything. That’s why this world went from perfection in the garden of Eden to being the sick and depressing place it is today. Do you think God would allow any of that stuff in heaven? Of course He wouldn’t. If heaven is going to be a perfect place, by definition there can be no sinners in it. None at all.”
