Therefore if any man be in Christ, he is a new creation: old things are passed away; behold, all things are become new.
All Commentaries on 2 Corinthians 5:17 Go To 2 Corinthians 5
John Chrysostom
AD 407
We ought to live for Christ not just because we belong to him, not just because he died for us and not just because he rose again on our behalf. We ought to live for him because we have been made into something different. We now have a new life. The old things which have passed away refer to our sins and impiety, as well as all the observances of Judaism.
