What is spiritual warfare?

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.

For though we walk in the flesh, we don’t wage war according to the flesh; for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds,

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. Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness, and having fitted your feet with the preparation of the Good News of peace; above all, taking up the shield of faith, with which you will be able to quench all the fiery darts of the evil one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God;

Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour. Withstand him steadfast in your faith, knowing that your brothers who are in the world are undergoing the same sufferings.

You are of God, little children, and have overcome them; because greater is he who is in you than he who is in the world.
