Ephesians 6: The armor of God

The armor of God is not a children's ministry cartoon. It is Paul's most concentrated spiritual warfare passage in the New Testament.

Historical context

Ephesians 5-6 forms the "household code" — instructions for wives/husbands, children/parents, slaves/masters. Chapter 6 continues with children-parents (1-4) and slaves-masters (5-9) before turning to the famous spiritual warfare passage (10-20). The letter closes with greetings and a benediction (21-24).

Three sermon arc options

• Children, fathers, workers. 6:1-9. The household code applied. Walk through the mutual obligations — children honor, fathers don't exasperate, workers serve as to Christ, masters don't threaten. Cross-applies to modern parent/child and employer/employee.
• The armor of God. 6:10-17. Six pieces of armor — truth, righteousness, gospel readiness, faith, salvation, the Word. Each is a gospel reality re-described as defense. The sermon walks through each piece, with care to keep the focus on Christ, not the Christian.
• Pray at all times. 6:18-20 as the often-overlooked seventh weapon. After the armor, prayer. Always praying, for all the saints, for boldness. The sermon ends where Paul ends — in dependence.

Original language notes

Endynamousthe ("be strong," v. 10) — passive imperative. Be strengthened, by another. The strength isn't self-generated. Stēte ("stand," v. 11, 13, 14) — military positioning. The believer's posture is defensive-stand, not offensive-charge. The victory is already won; we stand in it.

Five illustration hooks

• A Roman soldier's six pieces of armor — every reader in Paul's day would have known the parts. The metaphor is concrete, not poetic.
• A child instructed to stand their ground while parents fight off the intruder — that's the believer in spiritual warfare. The fight is already won; we stand in the victory.
• A father who doesn't exasperate his children (v. 4) — the rare positive command in this section, often the hardest one for fathers.
• Workers serving "as to the Lord" — every cubicle, every shift becomes liturgy.
• The shield of faith catching "flaming arrows" — ancient warfare used pitch-tipped arrows. Faith doesn't deny the arrows; it quenches them.

Cross-references

• Colossians 3:18-4:1 — The parallel household code.
• 1 Peter 3:1-7 — Peter's version of household instructions.
• 2 Corinthians 10:3-5 — Spiritual warfare in Pauline terms — the parallel passage.
• Isaiah 59:17 — God himself wearing the armor — Paul borrows the imagery.

Pastoral application

Don't turn the armor into a cartoon. Don't skip it because it's been overused. The pastor's job is to recover the seriousness of what Paul wrote — and to land prayer (vv. 18-20) as the strategy. The armor list ends in prayer because Paul knew the war is not won by Christian effort.
