Ephesians 6:10-20 (NASB)

The Armor of God
10Finally, be strong in the Lord and in the strength of His might.
11Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil.
12For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
13Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm.
14Stand firm therefore, HAVING GIRDED YOUR LOINS WITH TRUTH, and HAVING PUT ON THE BREASTPLATE OF RIGHTEOUSNESS,
15and having shod YOUR FEET WITH THE PREPARATION OF THE GOSPEL OF PEACE;
16in addition to all, taking up the shield of faith with which you will be able to extinguish all the flaming arrows of the evil one.
17And take THE HELMET OF SALVATION, and the sword of the Spirit, which is the word of God.
18With all prayer and petition pray at all times in the Spirit, and with this in view, be on the alert with all perseverance and petition for all the saints.
