Jerk
You're forgetting that we didn't know. Is it really a sacrifice? If by 'sacrifice' you mean the person is dead...well, that did happen. If the raising from the dead, meaning the person is physically alive again, nullifies the 'sacrifice' then it's not a 'sacrifice'.
How is it a sacrifice? What does the whole passion tell you? Jesus was alive in the beginning, and alive at the end, but in a different way. What happened in the middle? A crucifixion. A death. Torture. Pain.
So what does that say? It says we can go through pain as still be alive at the end. We are alive in a different way, though, which implies a transformation. Jesus teaches us this transformation through his own actions. That is the sacrifice.
So basically God made a human clone of himself and set it on a suicide mission so he could get permission from himself to forgive the sinners that he created to be sinful in the first place. I defy anyone to make less sense of the convulted mess that is the Bible.
