Hi,
Thought I'd come answer as I'm religious as it comes :).
My question is, if god supposedly forgives people for there wrong doings, then why does hell exist?
God doesn't forgive all. Mark 3:29 ...But whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of an eternal sin.".
Also, God only forgives if we ask him to, and have a good reason to be forgiven.
