It can be really hard to love the church. Every Christian, who’s been one for very long, knows this.

The earthly church has always been a motley crew. It’s never been ideal. The New Testament exists because churches, to differing degrees, have always been a mess — a glorious mess of saints still polluted by remaining sin, affected by defective genes, brains, and bodies, and influenced by life-shaping pasts.

This mess rarely looks glorious to us up close. It looks like a lot of sin and a lot of blood, sweat, and tears invested into a lot of futility. It often looks like something we’d rather escape than join.

But this is the way it’s supposed to be. Because the mess is what draws out the one thing that advances the church’s mission more than anything else. And this one thing is why we must not, for selfish reasons, leave the church.

The Church We Didn’t Choose

Jesus’s very first disciples didn’t get to choose each other. Jesus chose them (John 15:16). They just found themselves thrown together.

The very next generation of early Christians didn’t get to choose each other either. They too were thrown together with others they likely wouldn’t have chosen: Palestinian and Hellenistic Jews, Jews and Gentiles, educated and uneducated, slaves and slave owners, impoverished and aristocrats, former zealots and former tax collectors, former prostitutes and former Pharisees.

And Jesus gave these early disciples, and all disciples afterward, an impossible command: love one another (John 15:17). It had to be impossible to obey in mere human power because this love was meant to bear witness of Jesus in the world (John 13:35), and to give visible evidence of the invisible God (1 John 4:12). It had to demonstrate that “what is impossible with man is possible with God” (Luke 18:27).

And Jesus gave his disciples an impossible context in which to carry out this impossible command: the church (Matthew 16:18) — a community of diverse, sin-polluted, defective individuals from all sorts of life-shaping pasts living life together in an impossible love.

Then Jesus gave his church an impossible mission: preach the gospel throughout the whole God-rejecting, Christ-hating world (Luke 21:17; John 15:18), and plant impossible communities among every people where diverse, sin-polluted, defective individuals from all sorts of life-shaping pasts would live out Jesus’s impossible command to love one another (Matthew 28:19–20).

Impossible love, impossible community, and impossible mission: this is a plan doomed to fail. There’s no way this works, unless a God exists who makes possible the humanly impossible.

And here we are, two thousand years later. The impossible mission has produced impossible communities carrying out this impossible command throughout much of the world. For all the church’s problems, and they are legion, something miraculous is at work here.

Miraculous, Struggling Community

But the church rarely looks miraculous at any given moment. “The church,” as we most directly experience it, looks like the less-than-ideal local church we belong to, made up of ordinary people struggling to get along, struggling to figure out how to “do church” in a world of constant change, and struggling to do its part to fulfill the Great Commission.

Struggling doesn’t look or feel miraculous. It’s fatiguing, frustrating, and at times exasperating. Struggling can make us want to give up.

But we must not give up on the church. Because it’s the messy things — those extraordinarily difficult and painful things that can drive us crazy — that provide the very opportunities for the humanly impossible love of Christ to be exercised, giving visibility to the existence of the invisible God.

According to the New Testament, a church’s success is not measured by the number of its attenders, the size of its budget, the excellence of its event production, or the scope of its public influence. Its success is measured by the quality of its love. A church that most effectively witnesses Jesus in the world pursues love through:

• Honoring each other (Romans 12:10),
  
• Contributing to meet each other’s needs (Romans 12:13),
  
• Showing hospitality to one another (Romans 12:13),
  
• Rejoicing over each other’s joys (Romans 12:15),
  
• Weeping over each other’s griefs (Romans 12:15),
  
• Pursuing harmony with each other in spite of differences (Romans 12:16),
  
• Not excluding the lowliest members (Romans 12:16),
  
• Submitting to each other (Ephesians 5:21),
  
• Persistently striving for agreement over thorny issues (2 Corinthians 13:11),
  
• Using individual freedom in Christ to serve each other (Galatians 5:13),
  
• Bearing with each other’s weaknesses, foibles, and immaturity (Ephesians 4:2),
  
• Covering each other’s multitudinous sins with forgiveness (1 Peter 4:8; Colossians 3:13),
  
• Stirring up each other to press on in the mission of love (Hebrews 10:24),
  
• And not neglecting to meet regularly together (Hebrews 10:25).
  

And what calls such love out? Read each line again and ask what situations prompt such opportunities to love. The short answer is: lots of various kinds of struggling. It’s the messy struggles that call out love.

Churches are designed to be communities of impossible love that only work if God is real, and Christ’s sacrifice is real, and heaven is real. In void of love, the community falls apart or degrades into consumer event products, empty formalism, formless “spirituality,” social advocacy groups, or essentially civic gatherings — all dying or dead remains of a past vitality.

Graciously Disappointing Community

Jesus did not design the church to be a place where our dreams come true. Actually, it’s where many of our dreams are disappointed and die. And this is more of a grace to us than we likely realize, because our dreams are often much more selfish than we discern.

Our personal expectations easily become tyrants to everyone else, because everyone else fails to meet them. When we are more focused on how others’ failings and foibles obstruct the ideal community we want to pursue than we are on serving those others and pursuing their good and joy, our expectations can kill love, which impedes the real mission.

Jesus designed the church to be a place where love comes true, where we lay our preferences aside out of deference to others. It is meant to be a living laboratory of love, a place where there are so many opportunities, big and small, to lay down our lives for each other that the love of Christ becomes a public spectacle.

That’s why when it comes to church in this age, the picture of community we should have in our minds is not some utopian harmony, but Golgotha. In living life together, we die every day (1 Corinthians 15:31). We lay down our lives for each other (1 John 3:16).

Love the One You’re With

Over forty years ago, Stephen Stills sang, “If you can’t be with the one you love, honey, love the one you’re with.” Though he certainly didn’t write this with the church in mind, we can draw a redemptive application.

There are numerous legitimate reasons to leave a church, and departures are one more messy opportunity to extend gracious love. But we must have a healthy suspicion of our motives if disillusionment, restlessness, boredom, discontentment, burnout, relational conflict, and disappointed expectations are fueling our impulse to leave. Often these fruits have roots in selfish soil. We must not love the church we can’t be with — that idealized community of our imagination. We must love the one we’re with.

We don’t get to choose the disciples we live with; Jesus does. We get thrown into a motley group of sin-polluted, defective saints, among whom, in our own ways, we are the polluted, defective foremost (1 Timothy 1:15).

What we get is the incredible privilege of and plethora of opportunities for loving these fellow disciples like Jesus loved us. We get to love them, warts and all. Because it is through the mutually self-dying, forbearing, forgiving love warty disciples have for one another that Jesus is most clearly shown to the world and his mission is most powerfully advanced.
