This is necessary because our enemies are mightier than we are, more insidious and clever, more committed and experienced than we are; we’re fighting against principalities and powers, against spiritual wickedness in high places. (12) So we’re to take up all of God’s armor, not neglecting a single piece of it, so we can survive the battle and be standing when the dust clears. (13)
There are seven pieces in this suit of armor: a belt of truth and a breastplate of righteousness (14), the shin-plates and shoes of the preparation of the gospel of peace (15), the shield of faith (16), the helmet of salvation, the sword of the Spirit, the word of God (17) and prayer (18) – that constant communion with God which empowers the armor and helps it all work together.
Taking this armor, wearing and using it, is more than imagining that we’re putting on physical equipment and calling each piece by name, or fantasizing ourselves in virtual reality overcoming the dragon — much more than this.
The first piece, the belt of truth, is the foundation anchoring the breastplate and sword. We gird ourselves with truth, enveloping the core of our being, never tolerating any lying way within. We buy the truth and sell it not (Pr 23:23), not for any price, not ever. Without the love of truth we have no armor at all (2Th 2:10); walking in the lie we’re prisoners of war. (2Ti 2:25-26)
The breastplate of righteousness is our primary defensive armor, covering the vital organs; it’s the life pattern of obedience to Torah and springs from walking in light, obeying the truth. It comprises not merely positional righteousness; it’s faith in action, practical righteousness, loving in deed as well as in word. (1Jn 3:18) This is life-saving protection when the enemy strikes past our sword and shield; the good conscience of living in truth helps us abound in hope, glorying in trial (Ro 5:3), counting it all joy (Ja 1:2), not withering in shame. (1Jn 2:28)
The preparation of the gospel of peace is a second defensive covering; being rooted and grounded in the basics of the gospel, equipped to continually remind ourselves as well as share with others, this orients us properly in the world. This protects our feet and legs, for this is how we stand, how we journey. There is no standing outside of Christ, so we carefully defend our dependence on Christ: He is our peace (Ep 2:14), made to be sin on our behalf (1Co 5:21), reconciling us to God. (2Co 5:18) We glory only in Jesus Christ. (1Co 1:31)
The shield of faith, supernatural confidence in God, is the mobile defensive piece – the rest of the armor is fixed in place. We maneuver and position this shield to intercept the lies projected into us, which tempt us to fear, bitterness, strife and envy. We hold faith strategically, anticipating the lies, applying the promises of God in context to address each one.
The helmet of salvation is assurance of eternal salvation and security in Christ. (2Co 13:5) Failing to keep and maintain assurance of salvation destabilizes and incapacitates our souls, leaving us vulnerable to attack. (2Pe 1:10) We cannot joyfully serve Christ while we’re unsure if we even belong to Him. (9)
The word of God is the sword of the Spirit, our only offensive weapon. Without this we aren’t really in the fight at all, just a target waiting to be taken down. Taking up this sword requires hiding it in our hearts and meditating on it regularly, training ourselves so the Spirit can wield it as we quote when presented with any lie or temptation. This is the example of Christ (Mt 4:4, 7, 10); we follow His steps. (1Pe 2:21) There’s no other way to win.
The final piece is prayer, a weapon empowering all the other components to work together in the might of God. (2Co 10:4) In asking anything according to His will, He hears us (1Jn 5:14), engaging omnipotence in overcoming evil. (Ep 1:19)
We’re to take the whole armor of God, every single piece, because none of the individual pieces work properly without all the others working together. We might think of God’s armor as a single piece with many interconnected parts which all stand or fall together, a single living organism, energized by the life of God and infusing us with divine power. Take away one piece, and you’ve nothing worth having.
This spiritual armor is the very life of Christ in us, overcoming the evil one, each piece a way of portraying Christ Himself, the Word of Life (1Jn 1:1), the Way, the Truth, and the Life (Jn 14:6), our righteousness (1Co 1:30), our peace (Ep 2:14), our life (Col 3:4), standing with us and in us to overcome the world. (Jn 16:33)
Taking up the whole armor of God is, in a very real sense, bringing God Himself into the battle to fight within us, through us, and for us. (De 20:4) For without Him, we can do nothing. (Jn 15:5)
