Be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the evil one. For we are not contending against flesh and blood, but against the principalities, against the powers, against the world rulers of this present darkness, against the spiritual hosts of wickedness in the heavenly places.
Therefore take the whole armor of God that you may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having girded your loins with truth, and having put on the breastplate of righteousness, and having shod your feet with the equipment of the gospel of peace; besides all these, taking the shield of faith, with which you can quench all the flaming darts of the evil one. And take the helmet of salvation, and the sword of the spirit, which is the Word of God.
Pray at all times in the spirit, with all your prayers and supplication. To that end, keep alert with all perseverance, making supplication for all the saints, and also for me, that the utterance may be given me in opening my mouth boldly to proclaim the mystery of the gospel, for which I am an ambassador in chains; that I may declare it boldly, as it ought to speak. (Eph. 6:10-20)
