we don't get what we deserve

Isaiah 53:4
Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God and afflicted.

Often we can look at others and we want God to judge them, we want them to get what we think they deserve for their sin. We want to see God teaching them a lesson. No doubt the majority of the crowd at Jesus crucifixion were doing the same thing with Jesus. They judged that he was being punished by God for what he had said and taught. If that wasn't the case, if Jesus didn't deserve it, if he hadn't done anything wrong then why wouldn't God have protected him from this brutal death?

The reality is that Jesus didn't deserve the cross but he chose it, protecting us from the death we do deserve.
