Ephesians 6:14-17

Therefore, stand firm, having been girded about your waist with truth, and having been clothed with the breastplate of justice, and having feet which have been shod by the preparation of the Gospel of peace. In all things, take up the shield of faith, with which you may be able to extinguish all the fiery darts of the most wicked one. And take up the helmet of salvation and the sword of the Spirit (which is the Word of God).
