All this is done by God, who through Christ changed us from enemies into his friends and gave us the task of making others his friends also.
Our message is that God was making all human beings his friends through Christ. God did not keep an account of their sins, and he has given us the message which tells how he makes them his friends.
Here we are, then, speaking for Christ, as though God himself were making his appeal through us. We plead on Christ’s behalf: let God change you from enemies into his friends!
Christ was without sin, but for our sake God made him share our sin in order that in union with him we might share the righteousness of God.
