Ephesians 2:11

In view of what God has done for us in changing us, Gentile believers need to remember certain things. Paul used "flesh" here in the literal sense (i.e., the body) rather than in one of its metaphorical senses (i.e., the sinful human nature, or all that we are in Adam). Great differences existed between Jewish and Gentile believers before the Cross.

"The one word that best describes the Gentiles is without. They were ’outside’ in several respects." [Note: Wiersbe, 2:22.]
