Helmet of Salvation

The helmet of a Roman soldier, made either of brass or some other type of metal, was especially fitted to the shape of the soldier’s head, thus protecting the head from receiving a mortal wound from an arrow, a sword, or an ax. In Ephesians 6:17, Paul proclaims the good news that God has provided every believer with “the helmet of salvation” to protect him against the mental assaults of the enemy.
