Ephesians 6

10 Finally, be strong in the Lord, and in the strength of his might.

11 Put on the whole armor of God, that you may be able to stand against the wiles of the devil. 12 For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places [demons]. 13 Therefore put on the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. 14 Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness, 15 and having fitted your feet with the preparation of the Good News of peace, 16 above all, taking up the shield of faith, with which you will be able to quench all the fiery darts 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 all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints….
