THE COST OF DISCIPLESHIP

Is God Calling Me to Missions? How to Know for Certain

ttdf_d3ef645f · · 19 min read

Perhaps you sat in a missions meet recently. Someone showed photographs of a distant country and said thousands there have never once heard the name of Jesus. Weeks later, you’re still troubled by it. So you typed the question into a search box: is God calling me to missions?

The Bible gives us real answers, but not the answer most people expect. Most people wait for a voice, a dream, or a feeling strong enough to settle doubt forever. They wait for months, nothing comes. Others do feel something powerful, rush off to the far side of the world, only to return two years later, feeling wasted, crushed.

Scripture points us somewhere far solid. It gives us four things we can actually see, test and check. And the answer may surprise some: this question isn’t ours to answer on our own.

The question behind the question

When people ask “is God calling me to missions?”, they’re usually asking something else underneath: how do I know I am not disobeying God? That’s an honest fear. But notice where much of it comes from. Missions appeals often use pressure: statistics, photographs of children. And baits such as “If not you, who?” Some of that’s right and needed. But most load guilt onto tender consciences.

What God commands every single Christian

Begin with what’s certain. Jesus said: “Go therefore and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you” (Matthew 28:19-20).

This is the Great Commission. A “commission” is an order given to someone being sent out. Notice who receives it: not one man, and not a special class of super-Christians, but the gathered disciples—which means the church. The Heidelberg Catechism (1563) asks in Question 32 why a believer is called a Christian. And answers in part that I may confess His name. That’s every believer. No exceptions.

So we need no special calling to care about the nations, pray for them, give to them, or speak to our neighbour about Christ. All of that’s already clearly commanded. The question isn’t am I under the Great Commission. I am. The question is whether the church should send me across the world to do one particular job within it.

TWO THINGS THAT AREN’T THE SAME THING

Every Christian is commanded. Matthew 28 binds the whole church. Nobody is exempt.

Not every Christian is sent. A foreign field is a particular assignment, given to a qualified person.

Why it matters: confusing the two is the biggest cause of missions guilt.

Two kinds of calling

Here’s a distinction that will help us more than anything else here. Francis Turretin, who taught in Geneva in the 17th century, separated two ways God calls a person into gospel work.

EXTRAORDINARY CALLINGORDINARY CALLING
Who received itApostles and prophets: Paul on the Damascus road, Isaiah in the templeEvery gospel worker since the apostles
How it cameStraight from God, with no go-betweenThrough the church, using ordinary means
How it was provedBy signs and wonders; it proved itselfBy tested character, gifts and fruit, and the church’s judgement
Available today?No. It belonged to the age when Scripture was still being writtenYes. This is the only route now open

Read the right-hand column again. That’s our column.

This dissolves most of the anxiety around the subject. We’re not failing to receive something; we’ve been looking in the wrong place. We’ve searched our feelings for an extraordinary calling: that kind of calling ceased when the apostles died. The ordinary calling, however, has sat in our churches the whole time.

Three verses that are often used wrongly

Preachers reach for the same handful of texts. Each says something glorious. None says quite what it’s made to say.

VERSEHOW IT’S OFTEN USEDWHAT IT ACTUALLY SAYS
Isaiah 6:8—”Here I am! Send me.”An invitation to volunteer for the mission fieldIsaiah is being made a prophet, sent to people who will not listen (6:9-13). Edward Young and Alec Motyer stress this is a commission to preach judgement, not a recruitment poster.
Acts 16:9—the man of MacedoniaWait for your own vision before you moveVerse 10 says they concluded God had called them. Even beside a vision, they reasoned. The vision was rare; the reasoning was normal.
Acts 13:1-3—”Set apart for me Barnabas and Saul”“The Spirit will tell you privately if you’re to go”The Spirit speaks to a gathered church at worship, which fasts, prays and sends. John Calvin notes the laying on of hands didn’t create the calling; it confirmed one already recognised.

If a verse has been used to press you towards a decision, ask what it’s really about. God doesn’t guide us by twisting His own words.

How God actually guides people today

If not by voices and visions, how? Deuteronomy 29:29 gives the key: “The secret things belong to the LORD our God, but the things that are revealed belong to us and to our children.”

GOD’S WILL COMES IN TWO SENSES

His secret will is what He has decided will happen, including where we will live in 10 years. We can’t read that. We’re not asked to.

His revealed will is what He has told us in Scripture: be holy, be honest, love and provide for your family, make disciples.

The trap: guidance anxiety comes from trying to read the first when God has given us the second.

John Murray, a careful Scottish teacher of the last century, put it plainly in his essay on the guidance of the Holy Spirit. The Spirit doesn’t guide believers by dropping fresh messages into their minds. He guides through the Scriptures already given, through circumstances God arranges, and through a mind Scripture has trained to think wisely. The Bible never treats wisdom as second best, but as the normal way of deciding. Sanctified common sense—good judgement shaped by the Word of God—isn’t a poor substitute for guidance. It is guidance.

The Westminster Confession of Faith (1646) says the same in Chapter 1, Paragraph 6: everything necessary for God’s glory and our salvation is set down in Scripture or drawn from it by good and necessary consequence, and nothing’s added by new revelations of the Spirit. Our impressions aren’t revelation. That’s liberating in both directions: a strong feeling isn’t a command. And the absence of one isn’t refusal.

The four tests of a genuine calling

Teachers across the centuries have arrived at strikingly similar tests. Charles Bridges set them out in the 19th century for men entering ministry. And Charles Spurgeon gave his own version to his students, warning them never to rest on voices, dreams or impressions.

TESTWHAT IT MEANSHONEST QUESTION TO ASK OURSELVES
1. Settled desireGod gives us not conference excitement, but a steady, prayerful longing that survives ordinary weeksHave I wanted this for two years, or two months?
2. Real aptitudeGod equips us to explain the Bible clearly even to people who disagree. Plus patience and an ear for languageDo others learn from me? Have they said so unasked?
3. Fruit where we already areGod normally confirms usefulness by first giving it at homeAm I speaking about Christ to my neighbours now?
4. Our church elders’ confirmationOur elders examine us over time and agree. Or don’tDo our church elders confirm the calling? Are we willing to hear no?

Notice what all four share: every one can be seen by other people. Not one lives inside our private feelings. God designed the test so we’re not left alone with our own heart, which Jeremiah 17:9 tells us is deceitful above all things. Notice the order too. Test four isn’t a rubber stamp on a decision already taken. It’s the decisive one.

Am I the kind of person a church can send?

A missionary who plants churches is doing an elder’s work in another language, so the standards of 1 Timothy 3 and Titus 1 apply. Hard field conditions don’t lower that bar. They raise it.

  • Character before ability. Paul’s lists are almost entirely about character: self-control, gentleness, hospitality, a good name with outsiders. Only “able to teach” is a skill.
  • Doctrine we can defend. One day we may be the only Bible teacher in the room. Whatever we don’t understand, our hearers will not learn.
  • A home that holds. Paul asks how a man can care for God’s church if he cannot manage his own household. Our marriage travels with us.
  • Duties we cannot walk away from. Most missionary failure isn’t doctrinal but domestic. 1 Timothy 5:8 binds us to our family, including ageing parents. Real obligations aren’t obstacles God forgot about; they’re part of His guidance.

Why we cannot send ourselves

Paul asks: “And how are they to preach unless they are sent?” (Romans 10:15). Charles Hodge, commenting on this verse, observed preaching assumes a lawful authority standing behind the preacher. Nobody appoints himself. That’s why the confessions speak so firmly here: the Belgic Confession (1561) says in Article 31 ministers must be chosen by lawful election of the church. And the Second Helvetic Confession (1566) warns in Chapter 18 no one should seize this honour for himself.

It’s what Acts 13 shows. The Spirit speaks—but in the assembly, at worship, with the leaders present. The church fasts, prays and sends. Then verse 4 says the Holy Spirit sent them. Both are true at once: God sends through His church.

AGENCIES AND CHURCHES TYPICALLY DO DIFFERENT JOBS

What an agency does: training, placement, visas, funds and care on the field. Many are led by godly and careful men who guard these things better than most of us would.

What a church does best: send. Sending is typically an act of the congregation that holds our membership, knows our life, and answers for us.

Where either can fail: an agency that never asks which church stands behind us, and a church that waves members off to missions without ever testing them, fail in the same way—nobody is left responsible for the person who goes.

What if the answer is “stay”?

Some will work through the four tests honestly and find the answer is no—perhaps for now, perhaps for good. But wait. That’s not a second-class outcome.

John Calvin wrote in his Institutes of the Christian Religion (Book 3, Chapter 10) the Lord assigns each of us a way of life, and that each calling is like a sentry post: the place our Commander has put us, where we stand until He moves us. The soldier at the quiet end of the wall is no less obedient than the one at the gate.

And the one who stays is no spectator. John writes to Gaius about travelling gospel workers: “Therefore we ought to support people like these, that we may be fellow workers for the truth” (3 John 8). Fellow workers—not sponsors, not an audience.

  • Give as a plan, not from whatever’s left at the end of the month, and pray by name for those you support.
  • Host and welcome. The nations have moved into our cities. The unreached may be your neighbour.
  • Send your best people. Churches that give away their strongest members are the ones God fills again.

“I SERVE ON MISSIONS BUT WAS SENT BY A PARACHURCH ORGANISATION, NOT A CHURCH. DOES THAT DISQUALIFY ME?”

No. A gap in our sending structure isn’t a verdict on our salvation, our gifts, or the fruit God has already given through our work. The reason Scripture ties sending to the church is care and accountability rather than paperwork—somebody has to know our doctrine, watch our marriage, defend us when we’re accused, and have the standing to call us home. So the question isn’t whether we carry the right label, but whether anyone’s actually doing those things for us. If our organisation’s leaders are themselves members and elders of local congregations, and they do that work, much of it may already be in place under another name. If nobody is doing it, the remedy is simple and available today: join a local congregation where you serve, or ask a church at home if it will take formal responsibility for you. And invite both to speak into your work. Almost every sound organisation welcomes that.

A word about heroes and guilt

Two dangers sit on either side of the road.

The first is the hero story. We retell the life of David Brainerd, who preached to the tribes of the American forests and died at 29. Jonathan Edwards published his diary and generations have been stirred by it—yet Brainerd was deeply melancholy, often ill and often in despair. Romanticise such suffering, and we teach young believers to chase an experience rather than serve a Saviour.

The second danger is guilt. Some go because they can’t bear to feel they’ve failed God. But we’re not accepted because we’re radical. We’re accepted because Christ obeyed perfectly in our place. Let’s go, if we go, as forgiven persons doing a job—not as one trying to earn forgiveness.

How a real sending usually unfolds

It almost never happens in one dramatic moment. It normally looks like this.

A typical timeline, from first stirring to being sent

  • Years 1-2—rooted. You’re a committed member of a local church, serving where asked. People know you well enough to speak honestly about you.
  • Around year 2—it surfaces. The desire won’t go away. You tell your elders—not to announce a decision, but to ask their help in testing one.
  • Years 2-3—tested and trained. You teach, evangelise locally and take on something unglamorous. Weaknesses appear; some get fixed, some don’t. Theological study begins, often with a short assignment abroad—not to “find your calling”, but to get a feel for real conditions.
  • Years 3-4—confirmed and matched. Your church agrees to send you. Only now are field, agency and partners chosen.
  • Year 4 onwards—sent and held. You go, with a church behind you that prays, funds, visits, and has standing to call you home if it must.

If your own process has jumped straight to the last line, stop and go back.

The certainty you were looking for

You came here wanting certainty. Here’s what’s certain. God will save people out of every nation. Jesus said, “And I have other sheep that are not of this fold. I must bring them also” (John 10:16). Must. The harvest isn’t a gamble.

That certainty has always fuelled mission, never frozen it. Gisbertus Voetius, a Dutch theologian of the 17th century, gave mission three goals: the conversion of the nations, the planting of churches, and above all the glory of God’s grace. A century later Andrew Fuller argued that the gospel must be freely offered to all—and his book set William Carey free to sail for India, expecting great things from God and attempting great things for God.

WHAT WE CAN KNOW TODAY

1. We’re commanded to make disciples. That’s settled and needs no confirmation.

2. We’re not required to hear a voice or see a sign. That’s not how God guides today

3. We’re asked to present ourselves to a church that knows us, and let it test us.

4. If it sends us, we go with joy. If not, we stay with joy, and continue to serve God where we are. Both are obedience.

So ask your elders for a meeting this month. Tell them what’s been stirring in you, let them look at you carefully, and accept whatever they see. That’s not a smaller answer than a voice from heaven. It’s a surer one.

Tough Questions, Honest Answers

Do I need a seminary degree or ordination before I can go?

Scripture nowhere requires a certificate, so the honest answer is that a degree isn’t the test—competence and confirmation are. But the work itself sets a high bar. You will be teaching the Bible to people who’ve never heard it, in a language that isn’t your own, often with no other teacher nearby, and you will face questions about origins, spirits, ancestors and suffering that a shallow grounding cannot answer. Most sending churches therefore ask for serious theological training of some kind, whether that’s a seminary course, a church-based programme or a long apprenticeship under your own elders. Ordination is a separate matter and depends on the role: a man who will preach, baptise and gather a congregation should normally be ordained by his sending church, while support workers are commissioned rather than ordained.

Am I too old to go to the mission field?

Almost certainly not, though the role may need to change. Agencies often set age limits for long-term first-time placements, mainly because language learning is harder later and health costs rise, but those limits belong to agencies and not to Scripture. Older believers bring what younger ones cannot: settled character, decades of watching God keep His promises, practical skills, and the freedom of grown children and completed careers. Many fields are desperate for exactly that—mentors for young workers, teachers for pastors, administrators, and grandparent figures in cultures that honour age. The four tests don’t change with age; only the shape of the assignment does.

Can a single person, especially a single woman, serve overseas?

Yes, and single workers have always been among the most fruitful in the history of missions. Paul commends singleness precisely because it frees a believer for undivided devotion to the Lord (1 Corinthians 7:32-35), and many places are open to a single woman that are closed to a married couple. The roles should fit the pattern Scripture gives for the gathered church: preaching and eldership are given to qualified men, while teaching women and children, evangelism, translation, medical work, education, hospitality and discipleship are wide open. What matters most practically is that no single worker is sent out alone into isolation—loneliness, not doctrine, is what most often breaks single missionaries. A sending church should plan the community around a single worker as carefully as it plans the work itself.

Do short-term mission trips help me discern a long-term calling?

They can help, but not in the way people usually hope. A two-week trip is far too short to test anything real, and often produces an emotional high that feels like guidance but is closer to a holiday feeling. What genuinely tests us is a longer visit—several months at least—spent under the authority of workers already on the field, doing ordinary and unglamorous work rather than a special programme built around our visit. Trips of that kind reveal the things we cannot learn at home: how we handle loneliness, illness, boredom, being misunderstood, even misrepresented, and being useless in a language we cannot yet speak. Let’s treat the trip as an examination we might fail, not as a confirmation we’ve already passed.

What should I do if my spouse is unwilling to go?

You should not go. You shouldn’t treat your spouse as an obstacle to God’s will. Scripture puts a real and binding duty on you towards your husband or wife, and God doesn’t lead one member of a marriage to disobey another duty He has clearly commanded. If a church is asked to send a couple where one is reluctant, it should decline—and any agency willing to overrule that is a warning sign. The right response is patience: pray together, learn together, visit together, and let the years show whether God brings you to one mind. Many couples who’ve waited find either the reluctant partner becomes the more eager one, or that the reluctance was a mercy protecting them from a placement that would have destroyed them.

Is raising financial support biblical, or should I fund myself through work overseas?

Both are biblical, and Scripture doesn’t force a choice. Paul plainly teaches those who preach the gospel should get their living by the gospel (1 Corinthians 9:14), and he received gifts from the Philippians. John commends churches that send workers on their way in a manner worthy of God. Yet Paul also made tents in Corinth so as not to burden a young congregation. The practical question is which model fits the field: some countries grant no visa to a missionary, so a real job is the only lawful way in, while other settings need a worker free from employment to give full time to teaching and translation. What isn’t optional is transparency—money should flow with the knowledge of your sending church, with proper accounts, and never in a way that makes you answerable to nobody.

If I go and then have to come home early, does that mean I misheard God?

Not necessarily, and this fear keeps many people on fields where they’re being destroyed. Illness, war, visa refusals, a child in crisis, an ageing parent and plain exhaustion are all things God uses to close a door, and none of them proves the original sending was wrong. Paul himself was driven out of city after city, and Barnabas and Mark left work unfinished. God isn’t only building a church overseas; He’s also shaping us, and a season on the field may have done exactly what He intended even if it lasted 3 years, not 30. Come home to your sending church, tell them the truth, let them care for you, and give the grief time. Then apply the same four tests again from where you now stand.
