sacred weapons for spiritual war

Over recent years, there have been many television shows aimed at helping people get properly dressed. Sometimes the premise revolves around experts helping people to pick the right outfit for a wedding. At other times, someone with a woefully poor fashion sense receives a total makeover with the help of fashion gurus and some serious spending. In a similar way, Christianity helps people become properly dressed, although not in the typical sense. Paul advises the Ephesians that there are certain things Christians must put off and others they must put on. More specifically, he tells them (and us) to put on the Christian armor so we can be properly equipped to stand up to the assaults that inevitably come our way in this spiritually dangerous world. God’s Armor According to the Bible, life is not a picnic but a  battle , an armed struggle against a powerful adversary. To engage in that battle properly, we need a spiritual makeover in which our flimsy, inadequate natural attire is replaced by suitable armor and weaponry. So Paul concludes his magnificent, gospel-saturated letter to the Ephesians with a final charge to be prepared to engage with the battle of life in the right way, dressed in the armor of God. Many people assume that, as Wikipedia puts it, the various pieces (the belt of truth, the breastplate of righteousness, the shoes of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit) are correlated to what Paul would have witnessed firsthand as the arms and armor of Roman legionaries during his life in the Roman Empire. This assumption, however, misses the fact that each of the pieces of armor has a rich background in the Old Testament, where they describe  God’s  armor — the armor that God himself dons to rescue his people. The Old Testament, not the Roman legionary, provided Paul with his inspiration — and if we miss this background, we may misinterpret and misapply the various pieces of the armor. Breastplate and Helmet The most obvious examples are “the breastplate of righteousness” and “the helmet of salvation” (Ephesians 6:14, 17), both of which are drawn directly from Isaiah 59:17. There the prophet says of God, “He put on righteousness as a breastplate, and a helmet of salvation on his head; he put on garments of vengeance for clothing, and wrapped himself in zeal as a cloak.” In the preceding chapters, Isaiah describes God’s promise to deal with the physical enemies of his people, especially Babylon. But now the prophet describes the divine warrior coming to deal with the far greater and more dangerous enemy of their souls: sin. God’s people have no righteousness of their own to bring; their best righteousness, apart from divine help, is nothing more than filthy garments (Isaiah 64:6). If the Lord were to deal with his people according to their own deeds, there would be nothing to anticipate but fearful judgment. But Isaiah declares that the divine warrior would not come as a wrathful judge; instead, he would come as their Redeemer to bring them salvation. Ready Feet Similarly, Paul’s image of “feet readied with the gospel of peace” (Ephesians 6:15, my translation) does not stem from observing Roman sandals; rather, the picture draws directly on Isaiah 52:7: “How beautiful upon the mountains are the feet of him who brings good news, who publishes peace, who brings good news of happiness, who publishes salvation, who says to Zion, ‘Your God reigns.’” Ephesians 6 and Isaiah 52 (together with Nahum 1) are the only passages in the Bible where the words  feet ,  good news , and  peace  occur together. “According to the Bible, life is not a picnic but a battle, an armed struggle against a powerful adversary.” This Old Testament background clarifies a potential ambiguity in Paul’s words. When Paul speaks of feet shod with “the readiness of the gospel of peace,” does he mean the readiness  given  by the gospel of peace or the readiness to  spread the good news  that brings peace? Many translations and commentaries opt for the former interpretation. But if Paul is thinking about Isaiah 52, then the readiness he has in mind is primarily the readiness to share the good news as heralds of the gospel. Heralds need good shoes to enable them to travel far and fast to bring their message to those hungry to hear good news. Isaiah imagines the watchmen bursting into joyful song on the walls of Jerusalem (Isaiah 52:8). Those who had long strained their eyes with fearful anticipation of an approaching enemy now herald good news of deliverance to the beleaguered citizens of Zion. Paul applies this same image to our privilege of hastening to share the gospel of peace with believers and unbelievers alike. Belt of Truth The belt of truth also comes from Isaiah. In Isaiah 11, God’s people, Israel, had turned their back on the light and chosen to live in darkness, spurning the Lord’s revelation. Yet God promised he would send a messianic figure from the line of David to deliver them. This coming King would wear righteousness as a belt around his waist and “faithfulness” as a belt around his loins (Isaiah 11:5). The Greek translation of the Old Testament uses the same Greek word ( aletheia ) for  faithfulness  in Isaiah 11 that Paul uses in Ephesians 6, where our English versions translate it as  truth . This messianic King will save his people and bring in the final blessing of peace — a peace that extends throughout creation (Isaiah 11:6–9). The toxic effects of the fall, brought about by the first Adam listening to Satan’s lies, would be reversed by this second Adam and heir of the line of David, whose foundational qualities are truth and faithfulness. Sword of the Spirit The sword of the Spirit, the word of God, is drawn from Isaiah 49:2. There the promised servant of the Lord says, “[The Lord] made my mouth like a sharp sword; in the shadow of his hand he hid me; he made me a polished arrow; in his quiver he hid me away.” In other words, the Lord was preparing his servant to come as a warrior with sharp words of judgment. In the original context, the servant was Israel, who was supposed to be God’s faithful servant, equipped by him to bring light to the Gentiles. Yet in Isaiah’s time, there was much that needed to be judged and condemned in Israel and Judah themselves. They were not fit to be the Lord’s servant, so he had to send his servant to bring light to them as well as to the Gentiles. “The armor is first and foremost God’s armor rather than ours.” This promised servant, the new Israel with a mission to historic Israel, is Jesus himself. Yet even though Jesus could have entered this world with sharp words of judgment, condemning all those who fall short of perfect righteousness, in his first coming he came to seek and to save the lost, both those from Israel and from the nations (Luke 19:10). In his second coming, Jesus will return as a warrior riding out on a white horse with a sharp sword coming from his mouth with which to judge all nations (Revelation 19:11–16). Shield of Faith The Old Testament background for the phrase  shield of faith  also clarifies an ambiguity in Paul’s imagery. When he says, “Take up the shield of faith, with which you can extinguish all the flaming darts of the evil one” (Ephesians 6:16), Paul is not saying that faith in itself has remarkable defensive power against Satan. Rather, he is saying that faith protects us from Satan’s attacks because faith takes hold of the power and protection of God himself. Throughout the Old Testament, it is God, not faith, that is repeatedly described as our shield. In Genesis 15:1 the Lord tells Abraham, “I am your shield; your reward shall be very great.” Proverbs 30:5 says, “[God] is a shield to those who take refuge in him.” God is our shield and refuge; he is our hiding place in the day of difficulty; his faithfulness will keep us safe when we are being shot at by arrows, flaming or otherwise (Psalm 91:4–5). Faith becomes our shield in Paul’s imagery because it is the means by which we flee to God for refuge. Christ the Warrior Most importantly, the Old Testament background challenges the common view that the Christian armor is primarily a set of disciplines we must perform to measure up as Christians. It is certainly true that God’s armor describes essential qualities for us to pursue passionately if we are to stand firm under Satan’s assault. Yet the armor is first and foremost God’s armor rather than ours. Through the gospel, the divine warrior gives us his equipment, which he wore first triumphantly in our place in his definitive struggle against the forces of evil. “Through the gospel, the divine warrior gives us his equipment, which he wore first in our place.” Jesus Christ is  the  triumphant warrior over Satan, death, and sin through his faithfulness and righteousness, and his victory is now credited to us as if it were our own. Because he stood firm in his battle, we Christians — weak, fearful, and unprepared as we so often are — also will ultimately stand. By faith, his righteousness becomes ours, and in Christ we have a shield of refuge in God, who will never leave us nor forsake us. This is the good news that we have been given the privilege of heralding far and wide throughout the world, as well as preaching to our own hearts on a daily basis. The armor of God speaks mercy and grace to broken sinners, and a salvation that the combined forces of hell itself can never steal from us, as we rest in him.
