Jesus wants to make us free. We are free from condemnation, free from having to worry, free from our guilt. God has given us the righteousness of Jesus: “God has made him who had no sin to be sin for us, so that in him we might become the righteousness of God.” (2 Corinthians 5:21)
It is a radical notion, to realize that our sin has been taken and given to Jesus, and the righteousness of Jesus has been taken and given to us. It’s as if we have switched places. He stands condemned, we stand free and secure. It is inherently unfair. He’s getting punished for something we did. And yet he’s happy to do it, enslaving himself to set us free forever.
In order to live, we must eat. That means, something else must die, weather it is a vegetable if we are vegetarians, or the animal that becomes our sandwich, something has died to keep us alive. All life functions this way: it lives off death, it survives because something else does not.
Jesus’ died to give us his spiritual life; he died in our place, so that we could live. He became a slave, so we could be free.
Romans 8:1-3, 2 Corinthians 5:17-21
