Ephesians 6:10–18
The Armour of God
The big idea
The armour is not equipment to acquire but Christ himself to put on, and almost all of it is defensive.
Context you need before you preach it
Every piece has an Old Testament background, and most of it is drawn from descriptions of God's own armour in Isaiah 59:17. Paul is not inventing a metaphor; he is handing the divine warrior's equipment to the church.
Note that the commands are passive and repeated: be strong, be clothed, stand. Paul says "stand" four times. This is holding ground, not advancing.
The outline
Be strong in the Lord — the strength is borrowed
vv. 10–12And the enemy is named as not flesh and blood, which rules out treating people as the opposition.
Truth, righteousness, and readiness
vv. 13–15The first three. Belt, breastplate, and shoes — foundational, protective, and about footing.
Faith, salvation, and the word
vv. 16–17The shield covers the whole body. The sword is the only offensive item, and it is identified as the word of God.
Praying at all times in the Spirit
v. 18Often treated as an appendix; grammatically it is part of the same sentence. Prayer is how the armour is worn, not an extra piece.
Application
- Your actual opponent is not the person you have been treating as one. Verse 12 is worth sitting on.
- The verb is stand, repeatedly. Faithfulness here is holding ground rather than conquering.
- One offensive weapon, and it is scripture. A Christian who does not know the Bible is unarmed in Paul's picture.
Where preachers go wrong on this text
- Turning it into six independent lessons and losing that the armour is fundamentally Christ.
- Overplaying the Roman-soldier detail until the sermon is about first-century kit rather than about God.
- Detaching verse 18 and losing prayer as the mode of the whole thing.
Other ways to structure it
The outline above is one defensible reading, not the only one. If it does not fit the congregation in front of you, these are legitimate alternatives:
- Preach the Isaiah 59 background, showing it is God's own armour being handed over.
- Preach the fourfold "stand" as the structure.
- Preach verse 12 alone as a sermon on how churches misidentify their enemies.
Illustrations that fit this text
Frequently asked questions
Is the armour of God literal spiritual equipment?
It is a metaphor built from Isaiah's picture of God as a warrior, handed to the church. The pieces correspond to realities — truth, righteousness, the gospel, faith, salvation, scripture — that are ultimately found in Christ rather than being items to collect individually.
