Victorious in Spiritual Warfare
Ephesians 6: 10-18
We have no armour of our own that will be armour of proof in a trying time. Nothing will stand us in stead but the armour of God. This armour is prepared for us, but we must put it on; that is, we must pray for grace, we must use the grace given us, and draw it out into act and exercise as there is occasion
6:14 girding your waist with truth The belt around a soldier’s waist held the breastplate in place and provided an attachment for the sword.
6:14b. Before a Roman soldier put on his armor, he put a belt around his waist. This held his garments together and served as a place on which to hang his armor. The belt of truth refers not to the facts of the gospel but to subjective truth, a believer’s integrity and faithfulness. As a soldier’s belt or sash gave ease and freedom of movement, so truth gives freedom with self, others, and God.
The breastplate of righteousness refers not to justification, obtained at conversion (Rom. 3:24; 4:5), but to the sanctifying righteousness of Christ (1 Cor. 1:30) practiced in a believer’s life. As a soldier’s breastplate protected his chest from an enemy’s attacks, so sanctifying, righteous living (Rom. 6:13; 14:17) guards a believer’s heart against the assaults of the devil (cf. Isa. 59:17; James 4:7).
6:15. This verse does not speak of the spreading of the gospel, for Christians are pictured in vv. 10–16 as standing, not advancing. Instead this refers to a believer’s stability or surefootedness from the gospel which gives him peace so he can stand in the battle.
6:16. The shield in a Roman soldier’s attire, made of wood, was about 2 1/2’ wide and 4’ long. It was overlaid with linen and leather, to absorb fiery arrows. Thus it also protected the other pieces of the armor; hence Paul used the phrase, in addition to all this. Of faith is a genitive of content; the shield consists of faith. The idea, then, is that a Christian’s resolute faith in the Lord can stop and extinguish all the flaming arrows of the evil one aimed at him. (Cf. “evil one” [Satan] in John 17:15; 1 John 5:19.)
The helmet and sword are the last two pieces a soldier takes up. A helmet, being hot and uncomfortable, would be put on by a soldier only when he faced impending danger. Having one’s head guarded by a helmet gives a sense of safety, so the helmet of salvation refers either to present safety from the devil’s attacks or to a future deliverance, “the hope of salvation as a helmet” (1 Thes. 5:8).
Finally, a Roman soldier would take in hand his sword, his only offensive weapon. Of the Spirit refers to the source or origin of the sword; hence it is “the sword given by the Spirit.” “The sword of the Spirit” is specified as the Word of God. “Word” (rhēma; cf. Eph. 5:26; Rom. 10:8, 17; 1 Peter 1:25) refers to the preached Word or an utterance of God occasioned by the Holy Spirit in the heart. Believers need this “sword” to combat the enemy’s assault, much as Christ did three times when tempted by the devil (Matt. 4:1–11).
