Life can come at us hard. One moment, we are healthy. The next, we are seriously ill. One moment, we are on top of the world. The next, we’re searching our car seats for loose change. Whatever Paul meant by “the evil day” in Ephesians 6, it can feel at times like we are in it, depending on the nature of the trial that confronts us. That is why Ephesians 6, that wonderful chapter on the spiritual armor, is relevant for all seasons. Whatever our evil day may be, our heavenly Father has given us what we need to maintain our faith in Christ—and our sanity. He has given us “the whole armor of God.”
Paul is clearly using figurative language when talking about this heavenly battle gear. As much as we like putting our kids in cardboard armor during Sunday school, the armor of God is not something that you can buy off the shelf. It is made up of articles like “the belt of truth,” “the breastplate of righteousness” (v. 14), the shoe-like “gospel of peace” (v. 15), “the shield of faith” (v. 16), “the helmet of salvation,” and “the sword of the Spirit, which is the word of God” (v. 17). These are all clearly spiritual and ethical qualities. And that final piece, “the sword of the Spirit,” ought to tell us what this whole armor is. Since the sword of the Spirit is the Word of God—God’s Word, not our words—the whole armor is a gift from God. It comes from outside of us (which explains why Paul says to “take up” this armor). This would imply that the belt of truth is not our own personal integrity, important as that may be for daily life. Nor is the breastplate of righteousness our own personal virtue, vital as that may be for good citizenship. The whole armor is your Father’s gift to you! And it had better be from Him if we are to stand a chance against these bad guys: “the rulers…the authorities…the cosmic powers over this present darkness…the spiritual forces of evil in the heavenly places” (v. 12). We are wrestling against ancient dark powers, great and malevolent intelligences, that shape whole civilizations over time. Standing against them in our own personal goodness would be as effective as shooting at tanks with a nerf gun.
