How The Gospel Creates, Sustains and Shapes True Community


In a previous post I talked about the function of community and why it is God’s good design for every Christian to join a local church, not give up on it, and become deeply involved in it. Today I want to talk about how the Gospel creates true community and how it must sustain and shape our community in a church.

1. The Gospel Creates True Community

Only the Gospel can create and unite a people from diverse ethnic backgrounds, social statuses, different genders and ages, different interests and hobbies, and all other kinds of diverse identities. And that’s because the Gospel says that our unity is not based on any of those things. Our unity is based on something objective, unchanging, and that is relevant to every single human being, namely the life, death and resurrection of Jesus Christ. And in Christ there is “no Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all.” (Col. 3:11)

As Dietrich Bonhoeffer once wrote,

“Christian brotherhood is not an ideal which we must realize; it is rather a reality created by God in Christ in which we may participate. The more clearly we learn to recognize that the ground and strength and promise of all our fellowship is in Jesus Christ alone, the more serenely shall we think of our fellowship and pray and hope for it.” (Life Togetherp. 30)

In the words of Michael Horton,

“When God raises our eyes from ourselves to his Son through the gospel, we begin to see ourselves surrounded by a community of people who are no longer simply neighbours but brothers and sisters. . .Christ and his gospel is the tie that binds. I did not choose these people to be my brothers and sisters; God did. Like me, they are elected, redeemed, called, and justified by God in Christ.” (The Gospel-Driven Life, p. 192).

2. The Gospel Sustains and Shapes True Community as the Basis of Our Fellowship

And if the Gospel is what creates our unity it is also what must sustain and shape it. Paul exhorts the Ephesians to unity based upon the unity that we already have because of the Gospel:

Eph. 4:1 I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, 2 with all humility and gentleness, with patience, bearing with one another in love, 3 eager to maintain the unity of the Spirit in the bond of peace. 4 There is one body and one Spirit—just as you were called to the one hope that belongs to your call—5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all and through all and in all.

You see, our unity is not based on our ethnic background, our common interests and hobbies, our gender, our age, our stage in life, our social status, or anything else but the fact that we are all one because of the Gospel.

And when we start to lose sight of this reality, our community will quickly degenerate and become merely a social club or worse we will become divided and break apart. We’ll start to think, “I have nothing in common with these people.” But the Gospel says “Yes you do. . .you have something in common with every single one of them!” You all are sinners who have been purchased by the precious blood of the only begotten Son of God. You all have the same Heavenly Father. You all have the same Holy Spirit. You all have God’s Word and the same baptism and a common communion table. Some of us might share a few other things in common, but we ALL as Christians share these things in common. And so, we have to keep the Gospel central, in preaching, in our hearts, and in our conversations and actions towards each other. If you want to experience something you have in common with your fellow church members start talking more about the work of Christ with them rather than always talking about your favorite hobby, interest, political opinion, sports team, and other things that cannot unite a people from every tribe, and language and people and nation (Rev. 5:9-10).

In the words of Michael Horton,

“It is not my church to shape into my image, according to my own cultural preferences, ethnic background, politics, or socioeconomic location. It is Christ’s community–and he is the location that we all share together. He is the demographic niche and the political rallying point of this kingdom. I still belong to other groups based on my cultural affinities, but my family is not something I choose; it is something I am chosen for. . .the words and sacraments of the world create affinity groups for those with similar tastes based on generational, socioeconomic, political, racial, and consumer demographics. However, when the Spirit comes through his Word and sacraments, “the powers of the age to come” break into this present evil age (Heb. 6:4-5). The church becomes a cross-cultural community in the truest sense, defined by Christ’s work rather than our own” (The Gospel-Driven Life, p. 193).

3. The Gospel Sustains and Shapes Community by Demolishing Our “Ego Barriers”

And we have to keep the Gospel central because building community doesn’t come natural to us because of our sin. Our egos get in the way ALL the time. And only the Gospel can kill our pride. In the words of the hymn: “When I survey the wondrous cross On which the Prince of glory died, My richest gain I count but loss, And pour contempt on all my pride. You can’t think deeply about the Gospel and continue to be proud. You also can’t think deeply about the Gospel and continue to be insecure, desperately living for the praise of men.

As Tim Keller notes,

“Our natural condition under sin is to be ‘glory empty’–starved for significance, honor, and a sense of self worth. Sin makes us feel superior and overconfident (because we are trying to prove to ourselves and others that we are significant) AND inferior and underconfident (because at a deep level we feel guilty and insecure). Some people’s glory emptiness primarily takes the form of bravado and evident pride; for others, it takes the form of self-deprecation and self-loathing. Most of us are wracked by both impulses. Either way, until the gospel changes us, we will use people in relationships. We do not work for the sake of the work; we do not relate for the sake of the person. Rather, we work and relate to bolster our own self-image–to derive it, essentially, from others. . .the way to transparency, love, and mutual service is ‘blocked by our own ego.’ But when the gospel changes us, we can begin to relate to others for their sakes. It humbles us before anyone, telling us we are sinners saved only by grace. But it also emboldens us before anyone, telling us we are loved and honored by the only eyes in the universe that really count. So we are set free to enjoy people for who they are in themselves, not for how they make us feel about ourselves. Our self-image is no longer based on comparisons with others. We do not earn our worth through approval from people or through power over people. We are not overly dependent on the approval of others; nor, on the other hand, are we afraid of commitment and connection to others. The Gospel makes us neither self-confident nor self-disdaining but gives us boldness and humility that can increase together.” (Center Churchpp. 318-19)


And so, if we want to grow together in brotherly affection towards one another and experience more and more true community in our churches, then we have to grow deeper and deeper in the Gospel. The Gospel creates true community in a Christian church and it is what sustains and shapes that community. If we want to experience true community in our churches the Gospel has to be kept central and it has to grip us at the core of our being. Otherwise our egos will prevent us from loving each other freely for the sake of Christ. We will use each other to find significance in life and we will end up being merely a social club or worse we will “bite and devour one another” and will eventually “be consumed by one another” (Gal. 5:15). But when we are continually being reminded of who we are in Christ, it frees us up to love each other with brotherly affection and to experience true community, the kind that is a powerful witness to the world (John 17:20-23), a sanctifying experience that is good and pleasant (Psalm 133:1) and that brings great glory to our One God, Father, Son and Holy Spirit.

Seven Reasons Why Every Christian Should Join a Local Church, Not Give Up On It, and Get Deeply Involved


One Scotsman perhaps put it best when he doodled this poem during a sermon as he sat in the midst of his church members: “To dwell above with saints in love, Aye, that will be glory! To dwell below with saints I know, Now that’s a different story.” Some of us have read a few chapters of that “different story” throughout our life in the church. And if you haven’t yet, I can assure you that you will at some point if you are a part of a local church. The kind of true community envisioned in the Bible is something that we all long for and yet it often seems beyond our reach. And even when we reach it and get a taste of it, it’s hard to retain that experience. And so, some today have rejected the idea of the local church altogether. There are many professing Christians today who think the local church is irrelevant to their Christian witness, their Christian discipleship, and their personal relationship with God.

But when you get the function of community and see God’s wisdom in the Bible behind the idea of a local church, I believe it will cause you to value it, to want to be a part of it, and to strive to promote and maintain true community in a local church. And so, consider the following seven reasons for why every Christian should join a local church, not give up on it, and get deeply involved:

1. Your witness to the lost will be more compelling

First, think about how community functions in relation to our witness in the world. One of the most powerful things to the world is a community of diverse people getting along, loving each other, forgiving each other, being patient with each other, and persevering together through thick and thin. Just think of how many broken and divided communities there are in the world. There are broken marriages, broken families, church divisions, nations warring against each other, institutions breaking up, and the list could go on and on. The world is filled with broken and divided communities because of how sin affects all of our relationships. How beautiful it must be then for the world to see a congregation of Christian believers made up of all kinds of quirky and sinful people loving each another and persevering with each other through all kinds of trials and conflicts. Indeed, as the psalmist writes: Psa. 133:1 Behold, how good and pleasant it is when brothers dwell in unity! As Tim Keller notes in his book Center Church, Christianity can produce some exceptional individuals that the world will notice and respect. But so can Atheism and many different religions. And people can just conclude that they are exceptions to the rule. But one thing that other religions cannot produce is the kind of loving community that the gospel produces. Is this not what Jesus taught when he prayed: “John 17:20 “I do not ask for these only, but also for those who will believe in me through their word, 21 that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me. 22 The glory that you have given me I have given to them, that they may be one even as we are one, 23 I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.

Jesus taught in John 15-17 that one of the main ways that people will know that we are his disciples and that God the Father sent Him and loves Him and us, is in the quality of our love for each other as a community of God’s children who have His Spirit of love. And so, you see, a self-sacrificial, loving community, where we treat each other as brothers and sisters, bear with one another, forgive one another, rejoice with one another and suffer with one another, and persevere patiently with each other is one of the most powerful things when it comes to our witness. If you want to see your family, friends, and neighbors saved, don’t simply pray for them and share the gospel with them. Those things are absolutely essential and may be enough for them to come to saving faith. But often more is needed. They need to see that the gospel can produce a community of love that is radically different from what they see in the world. And if they see it they will want to know more about the gospel. And our witness to them about Christ will be more credible and compelling. And so, in addition to prayer and sharing the gospel with your lost loved ones you need to become deeply involved in the community of a local church and be “eager to maintain the unity of the Spirit in the bond of peace” if you want to have a powerful witness to them (Eph. 4:3). No doubt we should never confuse community with the gospel or say that the quality of our community is what makes the gospel true or not. But the quality of our community will attract people’s attention and make them eager to hear the gospel and embrace it by faith.

2. You’ll have godly examples that will help you grow in godliness

Not only does community function as a powerful witness to our unbelieving family members, friends, and neighbors, community also functions in a vital way in relation to our character. Think about how Jesus not only taught about godly character but that he gathered around himself a community of disciples and modeled godly character for them as the Son of God in the flesh. Not only were they informed intellectually of what godly character should look like through His teaching, he demonstrated it for them in His actions toward God, them and others. And this is simply the principle that we all know well, namely that we learn best from example. And so, community is vital for shaping godly character in our lives in this way. We need to hear the call to Christ-likeness in God’s Word but we also need each other to model godly, Christ-like character. As Paul put it, “Be imitators of me, as I am of Christ” (1 Cor. 11:1).

3. You’ll have the opportunity to grow in Christ-likeness

Community also provides the opportunity for godly living. We simply cannot grow in godliness apart from the Christian community. The “one another’s” of the Bible cannot be lived out if we are lone ranger Christians. Take one passage for example, Rom. 12:9 Let love be genuine. Abhor what is evil; hold fast to what is good. 10 Love one another with brotherly affection. Outdo one another in showing honor. 11 Do not be slothful in zeal, be fervent in spirit, serve the Lord. 12 Rejoice in hope, be patient in tribulation, be constant in prayer. 13 Contribute to the needs of the saints and seek to show hospitality. 14 Bless those who persecute you; bless and do not curse them. 15 Rejoice with those who rejoice, weep with those who weep. 16 Live in harmony with one another. Do not be haughty, but associate with the lowly. Never be wise in your own sight. 17 Repay no one evil for evil, but give thought to do what is honorable in the sight of all. 18 If possible, so far as it depends on you, live peaceably with all. The primary context in which these commands are to be lived out is in the context of a local church, as Paul was writing to the Christian churches in Rome (Rom. 1:7). And plenty of other “one another” passages that were written to local churches could be mentioned here. The point is that you cannot grow in Christ-like character, in accordance with God’s Word, apart from being deeply involved in the community of a local church. This is why it’s completely backwards when someone says that they admire a person’s faith and Christian character when that person has little to no involvement in a church. This is why Christians are deceiving themselves when they think that when it comes to Christian discipleship and growth in Christ-likeness it’s no big deal to join a church and get deeply involved with it. The call to love one another and all the other “one anothers” of the Bible are to be lived out in the context of a local church community.

And if you are considering leaving your local church because you have been offended in some way, consider whether or not you are leaving right at the time when God is calling you to grow in patience, forgiveness, prayer for your enemies, humility, and love. How can you grow in those things apart from conflict? Conflict is inevitable, and it’s not fun, but it’s also an opportunity to grow in Christ-like love and prayer. It also often reveals our own sin and weaknesses and makes us more humble and dependent on God.

4. You’ll have the wisdom of a community

Life is not easy to navigate in general and it’s also not always easy to know how to apply God’s Word in such a complicated world full of complex relationships and circumstances. But there is wisdom in a multitude of counselors. There is also wisdom in those who have been Christians for many years and have been through all kinds of scenarios that challenge their faith and yet they keep on persevering by God’s grace. There are also many Biblical principles that take wisdom to know how to apply in our day and age. Some are quite clear, like the command, “don’t commit adultery.” But others are not as clear, such as honor one another (Rom. 12:10), restore those who have fallen into sin in a spirit of gentleness (Gal. 6:1), show hospitality to strangers (Rom. 12:13; Heb. 13:2; 1Pet. 4:9), and don’t be greedy (1 Cor. 5:10; Eph. 4:19). What does it look like to honor one another in our time and place? What does gentleness look like for this particular person? What is good hospitality in our culture? What does greed look like. . .how much is too much spending on myself? We all have blind spots and we all struggle with applying these Biblical principles in specific ways in our day and age. But there is wisdom in how to apply God’s Word in the community that a local church provides.

5. You’ll have the accountability you need 

We could also add that the local church provides us with the necessary accountability that we need as Christians. It’s incredibly hard to live according to God’s Word as individuals apart from the wisdom and accountability that the community of a local church provides for us. Apart from the accountability of brothers and sisters we are even more easily “prone to wander Lord I feel it, prone to leave the God I love” as the hymn writer once put it. Apart from the accountability of a local church we more easily succumb to the temptations of the world, the flesh and the devil.

6. You’ll come to know God better 

Community also helps us to know God better. As we get to know one another more and more as Christian brothers and sisters who share the same Heavenly Father, we will grow to know our Heavenly Father better than if we were apart. Tim Keller makes this point in his book Center Church by referencing C.S. Lewis. As some of you may know, C.S. Lewis was close friends with J.R.R. Tolkien. But he and Tolkien were also close friends with a man named Charles Williams. And when their friend Charles Williams died, Lewis made this profound observation: “In each of my friends there is something that only some other friend can fully bring out. By myself I am not large enough to call the whole man into activity; I want other lights than my own to show all his facets. Now that Charles is dead, I shall never again see Ronald’s [Tolkien’s] reaction to a specifically Caroline joke. Far from having more of Ronald, having him “to myself” now that Charles is away, I have less of Ronald. Hence true Friendship is the least jealous of loves. Two friends delight to be joined by a third, and three by a fourth. . .We possess each friend not less but more as the number of those with whom we share him increases. In this, Friendship exhibits a glorious “nearness by resemblance” to Heaven. . . For every soul, seeing Him in her own way, communicates that unique vision to all the rest. That, says an old author, is why the Seraphim in Isaiah’s vision are crying, “Holy, Holy, Holy” to one another (Isa. 6:3) The more we thus share the Heavenly Bread between us, the more we shall all have.”

Keller notes, “Lewis’ point is that even a human being is too rich and multifaceted a being to be fully known one-on-one. You think you know someone, but you alone can’t bring out all that is in a person. You need to see the person with others. And if this is true with another human being, how much more so with the Lord? You can’t really know Jesus by yourself” (Center Church, p. 314). This rings true in my experience. I know Jesus better as a Christian because I have seen how his grace has been sufficient for others in my church. I have seen how others feed on His Word by faith and cling to Him in all kinds of trials. And that teaches me something that I wouldn’t have learned about Jesus by myself. And so, we need the community of a local church in order to know our Triune God better.

7. Your assurance of God’s love will grow

Finally, community helps us to grow in the assurance of God’s love for us. Let me explain this with reference to our justification. If we repent of our sins and trust in Jesus Christ alone for salvation and rest solely upon God’s grace to save us, God’s Word declares us forgiven of all our sins and clothed in the righteousness of Christ which is imputed to us through faith alone. And there are many passages that tell us that this is true of us if we repent and believe in Christ. But that Word of promise, as great as it is when we read it for ourselves in private, is not nearly as powerful for our assurance as it is when spoken to us from someone outside of us. Dietrich Bonhoeffer made this observation in his book Life Together: “God has put this Word into the mouth of men in order that it may be communicated to other men. When one person is struck by the Word, he speaks it to others. God has willed that we should seek and find His living Word in the witness of a brother, in the mouth of a man. Therefore, the Christian needs another Christian who speaks God’s Word to him. He needs him again and again when he becomes uncertain and discouraged, for by himself he cannot help himself without belying the truth. He needs his brother man as a bearer and proclaimer of the divine word of salvation. He needs his brother solely because of Jesus Christ. The Christ in his own heart is weaker than the Christ in the word of his brother; his own heart is uncertain, his brother’s is sure.”

And so, you see, the Christian community is vital for the strengthening of our assurance of God’s promises. As a pastor, I get the privilege every week of assuring God’s people of God’s love for them in Christ through the preaching of God’s Word and the administration of the sacraments. And I can see it on their faces. I can see how powerful it is for them to have someone outside of themselves, who represents Christ to them, assuring them of God’s love. But it doesn’t have to end in the pulpit. Christians in a local church should also be encouraging one another in Christ of God’s love for his people on a regular basis. The promises of the Gospel are meant to be gossiped widely. They are meant to be publicly proclaimed to others in the context of a community. And we all need them to be spoken to us from outside of our uncertain self (even pastors need this). Our assurance of God’s love grows in this way in the community of a local church.


And so, do you see the wisdom of why God has called us to dwell together as a community of believers? Do see why his Word exhorts us not to neglect to meet together? Do you see why we need to gather together for worship, times of prayer, small group studies, hospitality in each others homes, serving alongside each other, and in other ways of practicing the communion of the saints? God’s good design for you as a Christian is to become deeply involved in the life of a local church. And so, my prayer is that if you are reading  this as a professing Christian and you don’t belong to a local church that faithfully preaches the gospel, administers the sacraments, and practices church discipline, that you will join a church like this and get deeply involved. And if you are already a part of a local church perhaps this will help you come to a better appreciation for why God has called you to be a part of a local church. And perhaps it will encourage you not to give up on your church but to press on in faith, hope and love with your brothers and sisters in Christ. And may God be glorified greatly in our midst as he saves others and sanctifies His people more and more until Christ comes again and we all dwell together in perfect unity and love!
