These are the full teaching notes for the Spiritual Battle class — goals, learning outcomes, opening discussion questions, and session-by-session content that moves from the text of Ephesians 6 to its theology and then to its application, for whoever is leading the class.
Each session closes with discussion and application questions and a single question aimed at how the material presses on a student’s own view of the world. The notes are written to be taught from directly, not simply read.
Ephesians 6:10-13 opens the New Testament’s fullest treatment of spiritual warfare, and it opens with a puzzle worth sitting with before racing to the armor list that follows. Paul has just spent five and a half chapters telling the Ephesians they are already seated with Christ in the heavenly places, already built into one new humanity, already strengthened with might through His Spirit. Then, in his closing words, he tells them to arm themselves for a fight. Why would people who have already won need to suit up for battle?
That is exactly the tension this passage resolves. “Finally, my brethren, be strong in the Lord and in the power of His might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places” (Ephesians 6:10-12). The victory is Christ’s and it is already secured; the opposition is real, organized, and still active against every believer trying to live out everything Paul has just described.
Two Greek words carry the weight of the passage. The verb behind “stand,” ἵστημι, and its compound ἀνθίστημι, “to withstand,” frame both the opening command and its repetition in verse 13 — and neither word describes an attack. Paul is not sending believers to hunt the enemy down; he is calling them to hold a position Christ has already won (Colossians 2:15). His rare word for the struggle, πάλη, pictures a close wrestling match rather than a distant campaign, and the opponent’s method, μεθοδεία, is calculated deception rather than open force.
This study opens the series for a reason: before naming a single piece of armor, it settles what the fight actually is, who is really strong, and what victory looks like. Everything that follows builds on that ground.
Ephesians 6:14-20 answers the question the previous passage deliberately leaves open. Paul has commanded the church to “put on the whole armor of God” and to stand against an organized spiritual enemy, but he has not yet said what the armor actually is. These seven verses supply the inventory: a belt, a breastplate, footwear, a shield, a helmet, a sword, and — closing the list — a call to pray.
“Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace; above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God; praying always with all prayer and supplication in the Spirit” (Ephesians 6:14-18). Notice the grammar: “stand” is the one command; girding, putting on, shodding, and taking describe the means of standing, not six further orders. Paul is not handing out a checklist. He is describing what a standing believer looks like.
Every piece has a source worth knowing. The breastplate of righteousness and the helmet of salvation both come from Isaiah 59:17, where God Himself wears them first: “For He put on righteousness as a breastplate, And a helmet of salvation on His head.” The belt echoes Isaiah 11:5; the gospel-shod feet echo Isaiah 52:7. That background is why Paul calls this “the armor of God” — not merely armor God issues, but armor God wears.
And the list ends, tellingly, not with a seventh weapon but with prayer. The armor is not a specialized kit unrelated to ordinary Christian living — every piece names something this letter has already described at length as simple Christian character. This study walks through each piece in turn, tracing both its lexical meaning and its Old Testament roots, so a believer can see clearly what he is actually putting on.
1 Peter 5:5-11 asks a question the Ephesians armor passage never quite answers: what actually makes a believer able to resist? Ephesians 6 supplies the equipment and names the enemy. Peter supplies the posture — and by the plain order of his sentences, he insists that the posture has to come first.
Peter writes to churches already suffering real persecution, and his sequence here is deliberate. Humility comes first: “be clothed with humility, for ‘God resists the proud, But gives grace to the humble.’ Therefore humble yourselves under the mighty hand of God… casting all your care upon Him, for He cares for you” (1 Peter 5:5-7). Only then does he name the enemy and issue the command to resist: “Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. Resist him, steadfast in the faith” (1 Peter 5:8-9). And only after that comes God’s own promised work: “the God of all grace… after you have suffered a while, [will] perfect, establish, strengthen, and settle you” (1 Peter 5:10).
The Greek verb behind “be clothed,” ἐγκομβόομαι, is rare enough to be worth pausing over — its cognate noun names the working apron a household slave tied on over his clothes, a small but vivid picture of humility as something put on deliberately, not simply felt. The command to “resist,” ἀντίστητε, is the identical verb Paul uses in Ephesians 6:13 and James uses in James 4:7 — the same held-ground posture, never an offensive word — and Peter qualifies it further: resistance is to be “firm in the faith,” solid and planted in something other than the believer’s own nerve.
This study reads 1 Peter’s closing section as Peter intended it: not a manual of tactics for fighting harder, but a description of the humble, dependent, watchful posture out of which real resistance becomes possible at all — one that ends, fittingly, in a work only God can finish.
James 4:6-10 contains the single most quoted sentence in the New Testament on spiritual warfare — “Resist the devil and he will flee from you” (James 4:7) — and it is also the sentence most often lifted out of its paragraph and used alone, as though resistance were a technique that works for anyone who tries it. James will not let that happen. He buries the command in the middle of a sequence, and the order is the argument.
The passage opens with a proverb: “God resists the proud, But gives grace to the humble” (James 4:6), then moves through a rapid string of short commands — “submit to God. Resist the devil and he will flee from you. Draw near to God and He will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded… Humble yourselves in the sight of the Lord, and He will lift you up” (James 4:7-10). Submission comes first. Resistance comes second. Drawing near, cleansing, and grieving over sin come after — and the whole passage opens and closes on the same note of humility.
The Greek sharpens the point further. James actually uses two different words for opposition: ἀντιτάσσω, a military term for drawing up battle lines, describes God’s stance toward the proud; ἀνθίστημι, the more familiar “withstand” already met in Ephesians and 1 Peter, describes what the believer does to the devil. Collapsing those two words into one loses a real distinction between a sovereign’s settled stance and a soldier’s held ground. And both “submit” and “humble yourselves” are passive-form commands in the Greek — closer to letting yourself be brought low than to a purely self-generated act of will.
James’s promise that the devil will flee is real. But he attaches it to a person who has first submitted, and who goes on to draw near, wash his hands, and grieve his sin — not to resistance attempted in isolation. This study takes the passage’s compressed five verses slowly enough to see the order James actually intends.
2 Corinthians 10:3-5 The first four passages in this series all describe a believer who holds ground — armed, clothed, planted, resisting an assault already underway. That is a defensive picture, and a class that has spent four studies inside it will eventually ask the obvious question: is standing firm all there is? Does the New Testament ever put a believer on the attack, and if so, against what? 2 Corinthians 10:3-5 is where Paul answers, and the answer is more specific than the popular use of these verses usually suggests.
“For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ” (2 Corinthians 10:3-5). Paul names three things to be dismantled — ὀχυρώματα, fortresses; λογισμοί, pieces of reasoning; and every ὕψωμα, every barrier raised against the knowledge of God — and then names the goal: not an emptied mind, but a captured one, newly loyal to Christ. The Greek word behind “casting down,” καθαιρέω, carries a documented figurative sense of to refute — Paul’s demolition is an argumentative act, not a mystical one.
One honest note belongs here, because it shapes how the passage is used. This text does not share the series’ key vocabulary of standing and withstanding; ἀνθίστημι and ἐνδύω are simply absent from it. Its place in this study is thematic rather than lexical, and it is more honest to say so than to manufacture a word-link that is not there.
The practical payoff is significant. Some wrong thinking in a believer’s life is not a passing thought but a fortified position, built up over years and defended by reflex. This study takes seriously that such strongholds can be pulled down — by weapons whose power is God’s, not the believer’s — and closes this five-part series on an active, hopeful note.
