Forgiveness of Sins in the Old Testament

The forgiveness that god pronounced on faithful worshippers in the old testament was not aly owing to animal sacrifices. The answers they were pointing to jesus, god's final, once for all, decisive sacrifice for sins. They were foreshadowing the blood shedding of christ. So it says in hebrews nine 12, christ entered once for all into the holy places, not by means of the blood of goats and calves, but by means of his own blood,. thus securing an eternal redemption. Now i think caren knows this, but what she may have overlooked is that not only does the sacrifice of christ extend forward as an eternal redemption, but also backward in history too.
