What a Missionary Is: Calling, Cost, Support

What is a missionary?

At the broadest level, a missionary is “one who is sent.” That phrase matters because it ties the word to sending, not merely relocating. When we call someone a missionary, we affirm that a church, a community, or God has commissioned them for the gospel’s advance—often where the message is not well known or where people face hardship.

We should hold two truths together. First: every believer is called to live as witness and servant in daily life. Second: there is a particular, costly form of sending where people leave home and family to live among another people for the sake of Christ. Those are related but not identical.

Remember the Moravians: a group that reshaped mission practice. In some cases they sold themselves into slavery to reach places closed to outsiders. That detail—intentionally becoming vulnerable to bring the gospel—shows why “missionary” often implies a sacrificial posture, not merely a brief trip.

Behind the Words: When New Testament writers used language of being sent, they meant a commission with purpose—not travel for adventure. The Greek missionary language carries judicial and relational weight: God sends, apostles go, churches commission.

The Heart of It: Being a missionary is not primarily a resume line; it is the willingness to be sent and to live among others sacrificially for the sake of the gospel.

Try This: Picture a neighbor who shares your last meal when the power goes out. Now imagine someone who trades the comfort of family for another country’s uncertainty so a whole community might hear the gospel—that interior commitment is the missionary posture.

There are edges to this definition that stir debate. Does a two-week team trip make someone a missionary? Not usually. Does a professional transferred abroad who intentionally lives as a witness and is sent by a church count? Sometimes—nuance and intentionality matter.

The Heart of It: Commitment matters more than geography.

Holding this distinction saves us from two errors: calling every Christian a missionary in the technical sense, and narrowing the word so tightly that we ignore faithful witness inside home cultures. If we prize the sending and sacrificial staying over mere travel, we will recognize both local witnesses and long-term sent workers rightly.

• Try This: When churches speak of “sending,” clarify whether you mean commissioning for long-term placement, short-term teams, or ongoing partnership.

How do missionaries differ from ordinary Christians?

We love the slogan painted on fellowship halls—“Now entering the mission field”—as a reminder we all represent Jesus. But the phrase can blur categories. Practically, an ordinary Christian lives out the Great Commission where they are: workplace, neighborhood, gym. A missionary accepts a different rhythm: relocation, cultural learning, language study, and often dependency on a sending community.

The difference is both functional and existential. Functionally, missionaries often need visas, specialized training, and long-term relational investment. Existentially, they accept daily culture shock, loneliness, and the slow work of trust-building. Recall the vivid scene a traveler described: sitting in a congregation in a foreign village, watching everyone kneel while an outsider later explained, “they were praying to their own village’s God.” That example shows how churches can blend local practices in ways that confuse the gospel.

Scripture anchors this distinction. In John 20:21 Jesus commissions:

"As the Father has sent me, even so I am sending you." — John 20:21

This is sending into mission-shaped life, not a call for comfortable presence only. The apostles embody the pattern: Paul’s missionary journeys in Acts show leaving home, establishing churches, and returning to strengthen disciples—a cycle of departure and pastoral care.

Behind the Words: John 20:21 follows the resurrection appearances; the disciples receive authority and mission as a continuation of Jesus’ own sending. The ancient audience heard this as vocational commissioning, not a metaphor for casual faithfulness.

The Heart of It: Missionaries are distinguished by being deliberately sent and often by the sacrificial costs they accept to live and work among those who need the gospel.

Try This: Imagine a young teacher in Paris who moves to a rural African town to open a school because there is no education for girls. She secures a visa through her skill, learns the language, and opens her home for conversation. She’s not merely traveling; she’s embedded, vulnerable, and sent.

Common misunderstanding: some say, “Everyone is a missionary when they leave church.” That flattens vocation. Loving neighbors at home is Christian life—worthy of honor—but sending implies an intentional, often sacrificial, commission.

Models are evolving. A “scattered” approach sees professionals enter countries by employment: mechanics open shops, teachers accept local posts, entrepreneurs plant businesses—low-profile ways to be sent from within daily systems.

Yet the title still carries weight. For those who have left family, language, and stability—sometimes to imprisonment or death—the church should receive them with gratitude. We honor them because they accepted cost for Christ.

Passport in hand, theology in tow: How should churches support missionaries?

We give money. We pray. We post updates. Supporting missionaries well involves far more than checks and Instagram likes. Think relationally, theologically, and practically.

First, relationship matters. When a church decides to invest gospel resources behind a person, know them, know their sending organization, and understand their goals. A relational triad—know the individual, the organization, and the work—prevents well-meaning funds from enabling poor practice.

Second, reckon with history. The colonial era included a terrible strategy: conquest plus conversion. A blunt truth from candid conversations still rings: "Conquered for Christ. That's just awful." We must face how mission and empire were tangled—and how that legacy still wounds.

Confess that some historical missionary endeavors accompanied violence and cultural domination. The result in many places is syncretism: local customs mixed with Christianity in confusing ways. For example, some churches began hosting animal sacrifices on their grounds as local religiosity fused with imposed Christian forms. Those are painful details that demand pastoral humility.

Behind the Words: The missionary enterprise in early modern centuries was often entwined with imperial expansion. Conquerors planted flags and faith simultaneously; this produced Christian identity by power rather than witness.

The Heart of It: Support rooted in humility and long-term partnership undoes the damage of coercive missions by prioritizing listening, repentance, and local leadership.

Try This: Picture a missions committee asking: Have we listened to local leaders? Who will lead when we leave? Are we funding dependency or equipping for local flourishing? Then send a delegation not to take over but to learn, bring resources, and exit when leadership is ready.

Third, practical support takes varied forms: financial underwriting for long-term workers, training and debriefing for short-term teams, language-learning funds, counseling for culture shock, and partnership with trusted mission agencies. Some models encourage those with job skills to earn visas legitimately—mechanics opening shops, teachers taking posts—and be witnesses from inside systems of daily life.

The Heart of It: Support keeps people on the field longer and healthier when it is relational, accountable, and oriented to local empowerment.

• Try This: Build a support plan that includes monthly check-ins, a cultural training budget, a debrief after each trip, and an exit strategy that hands leadership to local believers.

Finally, honor sacrifice. When people leave stable lives to serve the gospel, say “thank you” in tangible ways: consistent financial partnership, regular prayer, pastoral care, and a posture of listening when critique arises. That honors both the missionary and the communities they serve.

We live in a season that calls us to rethink how we name and support those who take the gospel beyond familiar borders. Saying someone is “one who is sent” matters; it recognizes a distinctive posture of sacrifice and commission while preserving the ordinary Christian witness. Both are necessary for the life of the church.

Ask honestly: are you feeling tugged to go? Or to send? Either way, come with clarity. Take time to learn a language, build relationships, and discern calling with a sending community. And when you support someone, do it as family—steady, accountable, and full of gratitude for those willing to be vulnerable to bring Jesus to others.

Scripture for reflection

"Have this mind among yourselves, which is yours in Christ Jesus...who, though he was in the form of God, did not count equality with God a thing to be grasped..." — Philippians 2:5-7

These verses show Christ’s self-emptying humility (kenosis) as the model for mission: missionaries follow a Savior who gave up status and comfort for the sake of us all.

"The Spirit of the Lord is upon me, because he has anointed me to proclaim good news to the poor..." — Luke 4:18

Luke’s mission statement grounds ministry in proclamation to the poor and marginalized—reminding us that incarnational mission attends to spiritual and material needs.

"As the Father has sent me, even so I am sending you." — John 20:21

This commissioning ties our sending to Jesus’ own mission: sentness is vocational, communal, and intentional.
