Finally, my brethren, be strong in the Lord and in the strength of his power.

Put on the whole Armor of God, so that you may be able to stand against the wiles of the devil.

For our struggle is not against enemies of the blood and flesh, but against the rulers, against the authorities, against the cosmic powers of the present darkness, against the spiritual forces of evil in the heavenly places.

Therefore take up the whole Armor of God, so that you maybe able to withstand on that evil day, and having done everything, to stand firm. 

Stand therefore, and fasten the Belt of truth around your wait, and put on the Breastplate of Righteousness. 

As shoes for your feet put on whatever will make you ready to proclaim the Gospel of Peace;

With all these, take the Shield of Faith, with which you will be able to quench all the flaming arrows of the evil one.

Take the Helmet of Salvation, and the Sword of the Spirit, which is the word of God:

Praying in the spirit at all times in every prayer and supplication. To that end keep alert and always persevere in supplication for all the saints. 

Pray also for me, so that when I speak, a message may be given to me to make known with boldness the mystery of the gospel, for which I am an ambassador in chains. Pray that I may declare it boldly, as I speak. 

Ephesians 6:10–18 (KJV)
