Having covered each component of the armor of God, we understand that we cannot succeed against the Devil if we rely on ourselves. We need the belt of truth to keep the daggers of false doctrine from cutting our legs out from under us. Christ’s imputed righteousness gives us ultimate protection from condemnation and accusation, and the breastplate of a Holy Spirit-developed righteous character guards against the powerful blows of sin that try to destroy our hearts….
The shoes of the gospel of peace give us solid footing and ready us to fight. Faith acts as a shield that drives us to seek shelter in God against the flaming arrows of enticing temptations. Salvation, our helmet, protects our minds, enabling us to remain focused on the kingdom. God’s Word is our mighty sword, the weapon that brings the Lord’s enemies to submissive repentance and keeps us on the narrow way by forcing us to our knees in gratitude for salvation and sorrow for sin (Eph. 6:10–17).
