Christ ChurchINTRODUCTION
John Bunyan, in his book Holy War, once typified our personal battle against sin, the devil, and the world as a warfare against a city. He took the various attributes of both the body and soul and represented them as a city besieged by an array of threats. I want to attempt something similar, but applied to the life and work of the church. As is commonly said, the story of Scripture began in a garden, but it will end in a garden city that fills the whole earth.
THE TEXT
Glorious things are spoken of thee, O city of God. Psalm 87:3
CITY WALLS
The church is not an amorphous entity with indefinite boundaries. The liberal wants the walls of the city of God to be all-encompassing. The hidebound legalist wants the city walls to be just big enough for the handful of people they agree with…for now. But the Bible defines for us where the city walls are for the Church.
These walls require us to look at them as they are at present and then look in faith to when they will encompass the whole world. Jeremiah describes what will one day be true of the entire globe: “And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more (Jer 31:34).” The liberal wants the city walls to be universal right now; the purist wants to hold off on any expansion plans until the final trump shall sound.
City walls are essential. They serve two functions: keeping in and keeping out. That wonderful line from Tolkien comes to mind, “I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend.” Walls surround the citizens so they know where they belong. Within these walls is your home.
The walls of this city are the Word and Sacraments. Or to put it another way, we dwell in Christ. The Apostle John uses the language of a dwelling place: “Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit (1Jo 4:13).” The walls of this city are Christ. His Word and His signs. Those who have heard His Word and received it by faith dwell in Him, for He places His covenant sign of water upon them, and He feeds them with Himself. We dwell in Him, while He dwells in us.
But the secondary function of a city’s walls reveals something which is offensive to many. The walls keep out. Our culture is drunk on the cheap wine of inclusion. The walls of the Gospel of Christ make it plain that the only salvation to be found is within the walls of this City, which is Christ, and the signs of citizenship. Throughout the story of the Church’s history, these walls of God’s commandments surround God’s people, and expel the enemies of these divine truths (Deu. 6:16-18, Acts 20:29, 1 Co. 5:11). There are only two types of people, and Scripture bears this out in a number of different figures: sheep and goats, wheat and tares, elect and reprobate, sons of God and sons of the devil.
One temptation we face is to mistake the lesser walls within the cities which mark out the different neighborhoods as the city walls themselves. The city walls are not our confessions of faith, or our books of procedures, or denominational lines. The City walls are the Word of Christ, and those who trust in Him as He is proclaimed in Scripture find refuge within those everlasting bulwarks of His righteousness. This is what Jesus teaches when He said, “All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out (Jhn 6:37).”
CITY GATES
After the erection of city walls, the next most important feature of city fortifications is the gate. In the ancient world, the gate functioned as the gathering place, the market place, and most obviously, the access point. A city gate is where it is most vulnerable. It can have impressive walls, but if the gate is compromised the city will be overrun by its enemies.
Continuing our analogy, for those who enter by faith, the gate is baptism. For those who prove to be enemies of the cross of Christ, the gates are church discipline. The WCF describes the stages of church discipline this way: admonition, suspension from the sacrament of the Lord’s Supper for a season; and by excommunication from the Church (WCF XXX.4). This follows the pattern Jesus laid out in Matthew 18. We also see an OT example of this principle acted out by Nehemiah breaking up the Sabbath market which had shown up in Jerusalem’s gates.
Those who come through the gate of baptism are not the exact same group of those who will dwell forever in the City of God when it’s full glory is revealed. This is what we commonly refer to as the visible vs invisible church. Too often believers recognize the significance of the church’s duty to welcome new saints (whether in infancy or in conversion) through the gates of baptism, but neglect that the church is also tasked with expelling false sons and barring the gates to apostates. There will be those who weep outside the city gates for all eternity gnashing their teeth, clawing out their eyes, and despairing. Some of those will have been baptized at one point, and their everlasting despair will be all the worse for having tasted the goodness of the Lord, only to fall away, hearing His words of judgement, “Depart from me, for I never knew you.”
Nevertheless, these city gates are not feeble cardboard. Baptism is not a gate from Wish or Temu. Baptism is a mighty gate, which really does mark the entrance out of the world and into the church. And if John’s vision is any indication, these gates are not only strong but they are beautiful. Your baptism really is a strong glory; therefore to apostatize, to walk out of those gates in high handed rebellion is a also a shameful horror.
CITY STOREHOUSE
The Word of God makes provision for the propagation and continuation of the Church. It does this in a few ways. First, the life of the Christian family, dwelling within the walls of Christendom fill the Heavenly Jerusalem with the next generation of worshippers. This is the family’s primary task, to raise up children in the nurture and admonition of the Lord (Mal. 2:15). Godly men, as Solomon teaches, make every effort to provide for future generations: A good man leaveth an inheritance to his children’s children (Pro 13:22a). This should be taken in both the material and spiritual sense.
Additionally, we see numerous instances of generational thinking. The Patriarchs blessing their sons. Moses handing things off to Joshua. David commissioning Solomon to build the temple. Paul telling Timothy to “commit thou to faithful men, who shall be able to teach others also (2 Tim. 2:12).” The city of God has a storehouse which faithful saints are to fill with the treasures of wisdom, the legacy of applying the Bible to all contexts of human life, and David’s burnished shields and spears of joyful Psalm-singing.
Where one generation neglects to fill the storehouse with good things, the following generation is poorly positioned to weather a siege by the enemies of error, sin, and compromise. Judah’s King Asa once plundered the treasury of the temple to pay the pagan Syrian king to go to war with his brethren in Israel; this significantly weakened Judah. Asa’s own health reflects this weakened state, as he ends his days with diseased feet, unable to go forth to plant his feet in conquest. All because he grew fearful of his circumstances, and instead of walking by faith decided to empty the storehouse for a foolish project.
CITY FORTIFICATIONS
One of the besetting follies of conquerers is to think that once peace is established the work is done. Many a victory has turned into a route because the would be victors became drunk on the spoil. The armor of God includes the need to have our feet shod with the Gospel of peace. This implies that the peace envisioned by the Gospel is not insular, retreat-ist, or communal.
Rather, once peace has been established the city must begin to think about expanding its footprint. This, like Israel of old, will be done bit by bit. While Christendom largely expanded North and West from Israel, we must not forget that there have been Christian churches found which date back to the 700s as far Northeast as Beijing. Missionaries have shed their bled in far off frontiers, and while their bones have long since turned to dust, the blood they shed for the Gospel is a seed which will, in future centuries turned into a glorious Gospel harvest bringing in once pagan nations into the newly expanded city walls of Christ’s global governance.
The Gospel Word, while we have been comparing it to city walls, is likened in Scripture to leaven expanding a lump of dough, or a mustard seed growing into a glorious tree, or a small stone turning into a global mountain. The City Walls are intended to be expanded to encompass the entire world. The universalist wants to tear down the walls in order to pretend that that somehow fulfills the Great Commission…tada no walls, now everyone is in the city! No, the walls must never be torn down, but they are to be steadily expanded by faithful application to every new hill, each new valley, each river and sea.
CONCLUSION
Walls, gates, storehouse, and fortifications for future expansion. That is the life the Church. The Word begets us and defines where the City is. The gates welcome repentant sinners into the life of the Glorious City of our God. The storehouses must be continually filled with the virtues of grace, the blessings of faithfulness, and the foresight for generational prosperity. The citizens must not rest until every hill and distant island is circumferenced by the strong walls of Christ our Lord. Indeed, glorious things of thee are spoken, oh city of our God.
