You Ephesians have been non-Jews from the time that you were born. The Jews ◄insult you/say that you are not God’s people► by calling you ‘those who are not circumcised’. They proudly call themselves ‘we (exc) who are circumcised’. They have allowed people to circumcise them to indicate that they are God’s people, but that has only changed their bodies, not their ◄inner beings/hearts►.
