If Jesus knew he was going to get out of the whole "death is kinda permanent" thing, it's not a sacrifice at all. It's more like a politician getting a picture taken of him washing clean dishes...
What Jesus sacrificed was living on Earth.
What Jesus sacrificed was his sinless life.
What Jesus sacrificed was that his sinless life would be a ransom for us.
Adam put us in the Pawn Shop of Death.
We needed someone from the outside to pay to set us free.
We can Not resurrect oneself or another so we need someone who can do that for us.
So, Jesus' sinless life was a ransom price Paid in Full for us to get us out of the Pawn Shop of Death - Matthew 20:28.
