The beauty of the gathered church is not merely her structure, but her Guest. “Lo, I am with you always, even to the end of the age” (Matt 28:20). Christ Himself walks the ranks. He inspects His soldiers, heals their wounds, and renews their vows. Every sermon heard is His voice. Every sacrament received is His touch. Every benediction spoken is His commission. The church is not a memorial society of a dead leader—it is the living headquarters of a reigning King.

Note: This article is part of the series Weapons for Building Christendom, where we are exploring the God-given armaments that Christians must wield if we are to see households strengthened, churches fortified, and nations brought under the dominion of Jesus Christ.

Victories are not planned when you are in the thick of battle. They are conceived beforehand, with careful planning, in war rooms. And in the cosmic conflict of redemption, where we are fighting to see the world conformed to the image of God, Christ has not left His soldiers scattered and hunkered down, planless and hopeless, in the throes of war; He has gathered them, armed them, and stationed them within His living fortress—the church to be prepared for war. The church, therefore, is His command center, His embassy of heaven, His headquarters on earth. There, week by week, He feeds His army, fortifies His saints, and issues the next week’s His orders. Thus, to sever yourself from the gathered church is to cut yourself off from God’s supply lines and command center, it is to discard your rations, and to wander into the wilderness of uncertainty without your marching orders. No soldier, however zealous, can long survive apart from the camp, the same is true of men and women disconnected from His Church.

The Church Is as Headquarters

When Jesus Christ ascended to the right hand of the Father, He did not establish a loose association of enthusiasts who gather once a week to sing some songs. He enthroned Himself as King over the cosmos and founded a kingdom that would never end. And where there is a kingdom, there must be a capital. And that is where the church comes in. The gathered church is that capital—an embassy of heaven planted upon the soil of earth.

“Upon this rock,” Christ declared, “I will build My church, and the gates of Hades will not overpower it” (Matt 16:18). That is not the language of clubs, hobbyists, pacifists, or a gaggle of cowards. The enemy kingdom has gates; the church has battering rams; and our job on earth is to batter. Gates are defensive structures—built to withstand assault—which tells us everything about our purpose. If hell has built a kingdom full of gates, then they at least understand what our role is better than we do. And while we nap in the clouds, Hell is fully awake—erecting as many gates as possible to hold us back. But even that cannot stop the church. Because of what Jesus has done, demons and principalities have been disarmed, stripped, and humiliated; and all they have left are their defensive gates—pitiful, trembling gates that cannot stand when we advance.

If we would simply do our job, they have as much hope of winning as a middle school girls’ soccer team against the men’s World Cup champions. The church of Christ is not meant to cower in foxholes or hide in trenches; she is meant to charge. We are to be confidently, courageously, and convictionally advancing in such a way that the very gates of hell splinter before us. And before that advance each week, we must have clear plans communicated to us in the church, heavenly food to strengthen us from the church, and the Spirit’s orders to send us out from the church—so that we may scatter and tear down those hellish fortresses. If we leave the Lord’s Day assembly with any other mission than identifying the gates of hell and knocking them down, then we have missed the whole point of what it means to be Christian and to belong to a Christian church. Every faithful local church that preaches Christ crucified and administers the means of grace each Sunday is a siege engine aimed squarely at the walls of hell.

Each Lord’s Day, the saints are summoned to the King’s headquarters. There, strategy is set, strength is renewed, and the next offensive is launched.
