Forgiveness was never the issue. The Torah was given so forgiven people would know how to live, in order to be blessed. Your forgiveness was unconditional, but your blessing was conditional. You could live your whole life forgiven, saved to the bone, born again, child of God, I'll see you in heaven one day - but yet miss the whole blessing; that you live in darkness, disrepair, death. May you never say again: it's because my father ate sour grapes that I'm like this. No, when someone eats sour grapes, they are the ones whose teeth get set on edge.
