They are the people of Israel. They have been adopted as God’s children. God’s glory belongs to them. So do the covenants. They received the law. They were taught to worship in the temple. They were given the promises.
But we have been truly circumcised. We serve God by the power of his Spirit. We boast about what Christ Jesus has done. We don’t put our trust in who we are or what we can do.
So get rid of every kind of evil, and stop telling lies. Don’t pretend to be something you are not. Stop wanting what others have, and don’t speak against one another.
