There are 22 pages to read, maybe more, of responses! How could I read all of them? So I'll probably repeat a lot of what has already been stated.
I believe that a monotheistic God is the first source. I believe that humans have sinned in most ways against the creation of the universe as it was first spoken for when it broke apart. I believe in the religion of my family because it was the first thing I saw when my eyes opened to the possibility of a loving and alive universe, where people cared for one another because God made sure we had that aspect of bodily incarnation.
However my God doesn't condemn others to hell in the way the OP insinuated. For my God to work spiritually for me, it is an entity that doesn't contain a literal hell. When a person dies their soul will be as strong as they are when alive. Awareness and self-knowledge is the path to an after human life. God cannot say 'this person didn't believe in her heart that Jesus was the savior' b/c the person may really have thought it but not believed it.
No person will be condemned to a place without substance (love and connection-significance) without the permission of that person.
