Clear this up for me..

About the concept of "Hell", how can a person burn in hell after death. They are no longer physical human beings but spiritual beings and spirits can't burn.
I would think that God's true mercy would lie in the concept of reincarnation. You get to keep living over and over again until you get it right. Personally, I would be relieved very much so to know that I will live again as a new person instead of going to hell.
I think If people were sent to hell, it would be a waste of life and spirit. If I were God, I would put a halt to new spirits being created at all if so many people were lost and being sent to Hell. It would only make sense. Maybe someone can shed some light on this.
