Ephesians 6:10-13, 16-17

Finally, be strong in the Lord and in his great power. Put on the full armor of God so that you can fight against the devil’s evil tricks. Our fight is not against people on earth but against the rulers and authorities and the powers of this world’s darkness, against the spiritual powers of evil in the heavenly world. That is why you need to put on God’s full armor. Then on the day of evil you will be able to stand strong. And when you have finished the whole fight, you will still be standing.

And also use the shield of faith with which you can stop all the burning arrows of the Evil One. Accept God’s salvation as your helmet, and take the sword of the Spirit, which is the word of God.
