The Formation

The book of Ephesians is written to a group of believers. From the rich, identity-forming gospel truth at the beginning of Paul’s letter to his instructions at the end, he shares with community in mind. This includes the armor of God. As Paul unpacks the illustration, he doesn’t envision a single soldier but a legion. He describes the shield, understanding that one soldier’s armor alone can’t defend him. He also needs the shield on either side of him, before and behind him. Roman soldiers had a reputation for great success on the battlefield. One reason was the way they protected one another. Believers listening to Paul understand that not only is their own shield important in spiritual battle, they also need the faith of those around them.
