If
God is totally good, he is not Scrooge. He does not forgive some things; he
forgives all things. The only possible sin that cannot be forgiven is not
accepting forgiveness, which is why in traditional Christian theology, pride is
the worst of sins: “I am too good to be forgiven; there is nothing to forgive.”
