Mark Dever’s 65-page book Why Should I Join a Church? is part of a “Church Questions” series of quick-reads published by 9 Marks and Crossway. Since I have known Christians who see little reason to be part of a church and I was working on a sermon on church unity, I decided to give this quick read a quick read. With short books like this, it can often go one of two ways: (A) The book could be so short that it barely touches on the topic and is of little help or (B) since the book is short, it jettisons any unneeded wordiness and it answers the question clearly and concisely with laser-focus. I can’t speak of the other books in this series, but I found this short book to be give strong, clear, biblical answers to this question about being part of a church.
Dever shows how the New Testament writers needn’t give a command to join a church because the whole New Testament ASSUMES Christians are gathered in local churches. Heck, much of the New Testament writings are letters written to CHURCHES. Dever gives 6 good reasons why being part of a church community is so important, but he starts with the most powerful and persuasive reason: The love shown by fallen but redeemed Christ-followers in a local church displays to the world the Gospel of reconciliation, the core of the Christian message.
As I ended up writing in my sermon, any Christian who thinks he is too mature spiritually to be part of a local church body is, ironically, showing what he is lacking in spiritual maturity. He needs to be in a church, where fallen but reconciled Christ-followers can help each other grow together in faith. Part of that is learning to live with the messiness of others and to forgive them as Christ has forgiven us.
“Local churches are the place where we live according to this new reality [of reconciliation through Christ]. We don’t just say we’re reconciled, we show it. We show it by joining a congregation and committing to love one another and help one another grow in Christlikeness. We show it by inviting one another into our homes and caring for each other’s needs. We show it by confessing our sins to one another and forgiving one another. We show it by putting aside personal preferences and considering the interests of others above our own. We show it by learning and submitting to the word of God together. By joining a church, we commit to other redeemed sinners and show the world that Christ has indeed reconciled us both to God and to each other…
“What truly displays the gospel is when we commit to love and care for people that includes people utterly unlike us. We display the gospel when we gather each week to serve people who sometimes share only one thing in common with us: Jesus. We show we are reconciled in Christ when we commit to love those people in that place — no matter what faults and foibles they may have.”
