Ephesians 6:11-12 ESV
11 Put on the whole armor of God, that you may be able to stand against the schemes of the devil.
12 For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.
Ephesians 6:18-20 ESV
18 praying at all times in the Spirit, with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for all the saints,
19 and also for me, that words may be given to me in opening my mouth boldly to proclaim the mystery of the gospel,
20 for which I am an ambassador in chains, that I may declare it boldly, as I ought to speak.
