I heard this on NPR the other day and thought it might be of interest.
Carlton Pearson was a prominent evangelical preacher, until he came to realize that a god that would condemn people to eternal torment simply for not being christian is a monster. He decided that hell doesn't exist, and that the salvation offered by Jesus is for all of humanity, whether they believe in him or not. This did not go over well with his community.
