Ephesians 4:22-24

They taught you to change the way that you live. You must remove the nature that you had before. That old nature deceived you. As a result, you wanted to do things that would destroy you. Instead, let God's Spirit make you think in a new way. Take up the new nature that God has prepared for you. That nature is like God's own nature. Then you will live in a truly good way that pleases God.
