Watch Now

Pastor Mark Medley closed our eight-month journey through Ephesians—part of our In Christ series—by slowing us down in Ephesians 6:10–20 and reframing what many of us think when we hear “spiritual warfare.” Mark’s central insistence was simple but searching: the call to “put on the whole armor of God” is not a demand to hype yourself up for battle; it’s an invitation to stand in a victory Christ has already secured. The enemy is real and cunning, but the fight is not against people, and the strength for that fight does not come from our grit. We stand, he repeated, “in the Lord and in the strength of his might.”

To make it vivid, Mark began with the story of Hiroo Onoda, the Japanese intelligence officer who continued fighting for nearly thirty years after World War II ended because he didn’t know the war was over. It’s a haunting picture of sincerity and stamina propped up by a false premise. Too many Christians, Mark said, live like Onoda—waging endless guerrilla skirmishes against shame, fear, anxiety, or sin as if Christ has not already won decisive victory. That is why Ephesians opens with grace and peace and piles on the gospel: we have been chosen, adopted, forgiven, sealed by the Spirit, and raised with Christ above the principalities and powers. Before Paul ever speaks of a fight, he anchors us in what is finished. The armor of God, then, is not magical gear or a set of rituals; it is God’s own provision, purchased by Jesus, for living out what is already true.

At the same time, Mark did not minimize the reality of the battle. If some of us fight as if the war hasn’t been won, others live as if there isn’t a war at all. That is why Paul ends the letter with a sober reminder about rulers, authorities, cosmic powers over this present darkness, and spiritual forces of evil in the heavenly places. The conflict is personal and persistent, but it is not flesh and blood. In other words, people are never the enemy. The enemy is the one who deceives, divides, accuses, and inflames, often pushing us toward blaming those we can see while ignoring the forces we cannot. The gospel changes that frame and, with it, our strategy. Standing firm becomes less about mustering adrenaline and more about steady dependence on Christ’s finished work, daily obedience, and persistent prayer.

Mark also placed the armor in the flow of the whole letter. Ephesians is structured, he said, around three movements: we rest in the love of the Father and the work of the Son; we walk together in community with habits formed by a new heart; and we wrestle against the enemy from that foundation. That pattern is not theoretical. It prepares us for what Paul calls “the evil day”—those intense seasons when temptation spikes, suffering deepens, or conflict threatens to fracture relationships. To illustrate this, Mark told the story of Joshua Lawrence Chamberlain at Gettysburg. When his regiment ran out of ammunition on Little Round Top, Chamberlain led a bold bayonet charge that saved the Union flank and arguably the war. But, as Mark said, that victory did not begin on the day of crisis. Long before the smoke and chaos, Chamberlain had cultivated ideals and habits that shaped the man he would be when the hour struck. Likewise, Paul’s repeated call to “walk”—in love, light, wisdom, unity, good works, and the Spirit—forms us in ordinary days for extraordinary trials. Victory in spiritual battle is rarely born in the moment; it grows from decades of gospel-grounded walking.

With that frame in place, Mark walked us through the armor itself, showing how each piece sits inside the larger story of Scripture and the message of Ephesians. Paul borrows images from Isaiah 11, 52, and 59, where God Himself dons armor to fight for His people. The point is not to imagine ourselves as self-equipped warriors, but to see that we fight clothed in God’s own provision.

The belt of truth holds everything together. Truth here is not bare information but the reality of what God has done for us in Christ: forgiveness, adoption, sealing by the Spirit, being raised and seated with Christ, and being built together as God’s dwelling place. That truth also becomes truth we speak in love to one another. Because the enemy traffics in lies, discouragement, and distortion, we need brothers and sisters who will say what is real when our minds fog with fear or accusation. Truth is not merely an idea, Mark said. Truth is a Person—Jesus—who steadies our core.

The breastplate of righteousness guards the heart. Is this the righteousness given to us by grace or the righteous life we practice? Mark’s answer was a joyful “yes.” We “put on the new self” created in righteousness, and then we “walk” in light, pleasing the Lord. The imputed righteousness of Christ secures us; the imparted righteousness of daily obedience strengthens us. We neither trust our behavior to save us nor shrug at holiness because we’re “covered.” We receive and we walk.

The shoes of the gospel of peace anchor our stance. Again Mark pressed the double meaning: is this peace with God or peace with others? Yes. In Christ, God has made peace with us, and in Christ, He has made us one new humanity. It is startling imagery—going into battle equipped with peace—but that is precisely the surprise of the kingdom. Peace with God quiets panic; peace with one another keeps us from turning our weapons on the wrong targets. Reconciliation becomes both our footing and our witness.

The shield of faith extinguishes flaming darts. Is faith God’s gift to us or our trusting response to Him? Yes. Saved by grace through faith, we also live by faith in the faithfulness of Christ. Mark cautioned that our confidence is never in our ability to believe hard enough, but in the character and finished work of Jesus. When accusations fly or fears ignite, that shield is not our inner resolve; it is trust in a Lord who cannot lie and does not fail.

The helmet of salvation guards the mind. Is salvation a finished gift or something we put on daily? Yes. We rest in what God has done, and we actively remind ourselves of the gospel when our thoughts slip into condemnation or despair. Because the battleground often runs through our thought life, Mark urged us to rehearse good news: you are in Christ, raised with Him, loved, secured. The thing that protects your head is the one thing you cannot provide for yourself.

The sword of the Spirit is the Word of God. Mark explained Paul’s use of rhema, the timely, Spirit-breathed word that arises from the written Scriptures, the logos. The canon is settled and enduring, and the Spirit takes that living word and speaks it into our present moment. That means we need steady exposure to Scripture if we hope to hear the Spirit’s present-tense guidance. Christ saves us through the word of truth, and He keeps washing us by His word, strengthening, correcting, comforting, and arming us for battle.

If the armor scene conjures images of solitary heroes, Paul refuses to let it end that way. Mark noted how the passage flows directly into a call to pray “at all times in the Spirit” and to keep alert with perseverance for “all the saints.” Even Paul, the apostle who saw the risen Christ, planted churches, worked miracles, and wrote Scripture, asked for prayer: “that words may be given to me … to declare [the gospel] boldly.” My armor is for you, Mark said, and yours is for me. There are fights we cannot win without one another’s prayers. The end of Ephesians makes that corporate reality concrete: Paul does not only send a letter; he sends Tychicus, “the beloved brother and faithful minister,” so that their hearts might be encouraged. Ephesians is not a me-first letter. It is about God’s purposes in Christ and our life together as His household, His temple, His body. In this series—In Christ—we have learned to rest together in the gospel, walk together in Christlike character, and wrestle together against the enemy. None of those can be done alone.

Mark closed by turning from the ancient armor to the modern pew. You are a warrior, he reminded us, even if you don’t feel like one. Some battles are too personal to parade as stories, and some wounds remain tender. But our Shepherd knows how to tend those wounds and how to help us put on the right piece of armor when we need it most. He knows which brother or sister carries the words that will steady us, and He brings them to our side. We are not fighting alone, and we are not fighting in our own strength.

Because this is not a call to hype but a call to stand, Mark invited us to reflect personally before God. Name the real enemies—lies, fears, temptations, patterns of accusation—not the people who frustrate you. Then ask, What provision has the gospel already made for this? How can I ground myself this week in what has been done for me in Christ? Which Scriptures is the Spirit highlighting as my sword right now? And turn those same questions outward in love: Who am I fighting for? Where do they need covering in prayer? Who are my brothers and sisters who will stand watch with me?

In the end, the paradox held. Christ has won the decisive victory, and we daily apply that victory in His power. We are seated with Him in the heavenly places, and we stand firm on the everyday ground of our lives. We are clothed with armor bought by His blood, and we fight as one people, not one-by-one heroes. In Christ, the war is settled, but the love-shaped, truth-steeped, peace-anchored, faith-fueled, salvation-minded, Scripture-armed, prayer-soaked standing continues—together.
