“Spiritual warfare” refers to the Bible’s picture of the Christian life as an ongoing conflict against evil that is not fought with physical weapons. The phrase itself is not in most English Bibles, but the concept runs throughout scripture, most clearly in Paul’s letter to the Ephesians. Here is what it means and how the Bible describes fighting it.
What Does Spiritual Warfare Mean in the Bible?
Paul lays out the idea most directly in Ephesians 6:12: “For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.” The point is not that people are the real enemy. It is that behind human conflict, temptation, and evil, scripture describes a deeper spiritual opposition that Christians are called to resist, not with violence or manipulation, but with the resources God provides.
The Whole Armor of God
Right before naming the real enemy, Paul gives the main instruction for this kind of fight: “Put on the whole armour of God, that ye may be able to stand against the wiles of the devil” (Ephesians 6:11). He then lists specific pieces, truth, righteousness, the gospel of peace, faith, salvation, and the word of God, each pictured as armor a Roman soldier would have worn. The emphasis throughout is on standing firm and being prepared, not on aggression. Spiritual warfare in Paul’s picture looks more like defense and endurance than attack.
Not Carnal, But Mighty Through God
Paul makes a similar point to the Corinthians: “For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds” (2 Corinthians 10:4). The weapons in view throughout the New Testament are things like prayer, scripture, faith, and the truth of the gospel, not political power or force. This is a consistent thread in how the Bible describes resisting evil: real conflict, taken seriously, but fought on spiritual terms.

Frequently Asked Questions
Does spiritual warfare mean fighting against other people?
No. Ephesians 6:12 specifically says the struggle is “not against flesh and blood.” The Bible’s picture of spiritual warfare directs attention away from treating other people as the enemy and toward prayer, scripture, and character as the real battleground.
What is the most common piece of spiritual armor mentioned in Ephesians 6?
Each piece gets its own verse (Ephesians 6:14-17), but Paul closes the list by tying prayer to the whole picture in verse 18, describing it as praying “always with all prayer and supplication in the Spirit.” Many readers treat prayer as the piece that activates and sustains the rest.
