What do missionaries actually do? This simple question stirs endless debate in Christian circles. Some equate missions with raw evangelism—hit the field, share the gospel, move on. Others expand it to every good deed: digging wells, teaching literacy, or community development, as long as it's "in Jesus' name." Both miss the biblical mark. Kevin DeYoung, drawing from Acts 14:19-28, offers clarity through the apostle Paul's first missionary journey with Barnabas.
Picture the drama: Jews from Antioch and Iconium incite a mob. They stone Paul, drag him outside Lystra, and leave him for dead. Yet disciples surround him; he rises, re-enters the city, and presses on to Derbe the next day. There, they preach, make disciples, then loop back through Lystra, Iconium, and Antioch. They strengthen believers ("encouraging them to continue in the faith"), warn of tribulations en route to God's kingdom, appoint elders in every church after prayer and fasting, and commit these new leaders to the Lord. Finally, back in Syrian Antioch, they report to their sending church: God "opened a door of faith to the Gentiles."
This isn't daily logistics—it's the strategic essence. DeYoung calls it a "three-legged stool":
New Converts: "Having preached the gospel... and made many disciples" (v. 21). Missions pioneers where Christ is unknown, winning souls through proclamation.
Nurtured Churches: "Strengthening the souls of the disciples... through many tribulations" (v. 22). New believers need grounding, teaching to persevere amid suffering.
Established Leadership: "Appointing elders... with prayer and fasting" (v. 23). Disciples form healthy churches with godly oversight.
Eckhard Schnabel echoes this: Missionaries announce Jesus the Savior, teach a new way of life replacing old norms, and integrate converts into communities.
Not every Christian is a missionary. All obey the Great Commission locally, but missionaries are intentionally sent by churches to unreached frontiers—like Antioch commissioning Paul and Barnabas (Acts 13:1-3). The church (ekklesia) is "called out"; missionaries are "sent out."
Avoid pitfalls: Don't shrink missions to hit-and-run conversions, ignoring discipleship. Don't broaden it to social action alone—vital mercy ministry, yes, but Acts prioritizes verbal gospel proclamation (Rom. 10:14-15). Paul didn't build schools or wells; he preached Christ crucified.
Practical Implications
For Missionaries: Align with apostolic priorities. Be "people of the Word"—know it, believe it, preach it, teach it. Expect suffering; Paul modeled resilience.
For Churches: Budgets and prayers target this trio: evangelism, discipleship, church planting. Prioritize unreached peoples (7,000 groups, billions without access). Leverage strengths—language skills, partnerships—while meeting greatest needs.
For Aspiring Servants: If your heart burns for this gospel advance, talk to leaders. The need is extraordinary; the gospel matches it.
Acts isn't method-bound—no one-size-fits-all strategy. Today's missionaries learn languages, navigate cultures deeper than Paul's Roman world. Yet the goal endures: converts to disciples to churches.
Missionaries aren't superheroes. They need marriage support, parenting help, conflict resolution—like us all. Send them as servants of Christ, sustained by prayer.
Through many tribulations, the kingdom advances. May God raise faithful laborers for the harvest.
