10 Finally, be strong in the Lord and in the strength of His might. 11 Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. 12 For 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. 13 Therefore, take up the full armor of God, so that you will be able to resist on the evil day, and having done everything, to stand firm. 14 Stand firm therefore, having belted your waist with truth, and having put on the breastplate of righteousness, 15 and having strapped on your feet the preparation of the gospel of peace; 16 in 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. 17 And take the helmet of salvation and the sword of the Spirit, which is the word of God.
18 With every prayer and request, pray at all times in the Spirit, and with this in view, be alert with all perseverance and every request for all the saints, 19 and pray in my behalf, that speech may be given to me in the opening of my mouth, to make known with boldness the mystery of the gospel,
Ephesians 6:10-19 ESV
