To Reach the Unchurched, Build Up the Church

To Reach the Unchurched, Build Up the Church

The primary obligation of the minister who wishes to reach every pew from front to back is to preach the unsearchable riches of Christ to build up his body, knowing that the manifest presence of Christ through his preached Word will bring dark hearts into the light of his glorious grace. The unchurched see Christ in his church being made more like him. And that happens as men of God expound the Word of God to the people of God for the praise of God in his church.

Imagine that you’ve invited a non-believing, unchurched friend to the worship service at your church this Sunday. You’ve explained about the old-school songs that he or she won’t know, prepared them to let the communion plate pass, and even given them a heads up that the sermons can be kind of long. Now, as the preacher gets up into the pulpit, Bible in hand, you nervously shift in your seat, thinking about how your friend might receive what they’re about to hear.

Think about that moment. What do you hope the preacher will say? What do you hope the preacher won’t say?

The church growth gurus say that they know how that sermon can best reach your unchurch friend. The truly evangelistic preacher needs to address the life issues of your non-believing friend, preferably using up-to-date movie illustrations. He should preach about issues of injustice and present community concerns. Less judgment, more affirmation, less Bible, more conversation, and so on. You’ve heard it all before. The advice sounds, in summary, like this: “Leaders should focus on who they want to reach, not who they want to keep.”

According to the apostle Paul, that’s painfully backward. What preachers must say to reach non-believers in the pews, and what we should desperately want our unchurched friends to hear at church, isn’t necessarily what our unchurched friends want to hear. It’s what the church needs to hear.

The best way to evangelize the unchurched at church is to build up the church.

The logic of edification as evangelization seems counterintuitive to us, so let’s hear Paul explain it in his own words to the confused Corinthian Christians:

Brothers, do not be children in your thinking. Be infants in evil, but in your thinking be mature. In the Law it is written, “By people of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord.” Thus tongues are a sign not for believers but for unbelievers, while prophecy is a sign not for unbelievers but for believers. If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are out of your minds? But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, the secrets of his heart are disclosed, and so, falling on his face, he will worship God and declare that God is really among you.

1 Corinthians 14:20-25

Without explaining this whole passage, let me note the relevant pieces to reaching the unchurched at church. First, notice that the context of Paul’s exhortation is when “the whole church comes together” (1 Cor 14:23), a description of the Lord’s day assembling of the church for worship. Paul uses this same word for “come together” five times in 1 Corinthians 11 in discussing the practice of the Lord’s Supper, and again in 14:26 about the regular worship of the church. So, what Paul has to say applies to the Sunday gathering of the church, not another setting. If it were an evangelistic campaign, or street evangelism, or another venue, then Paul’s instruction would probably sound more like 1 Corinthians 9:22 “I have become all things to all people, that by all means I might save some.” But here, we’re just dealing with what believers should do when they come together as a local body on the Lord’s Day.

Second, notice that Paul makes a distinction between gifts meant for evangelism and gifts meant for edification.
