How to Become a Missionary
An Honest Guide

Most guides to becoming a missionary skip the hard parts. They talk about passports and support-raising and rarely about the years of testing that come first. Becoming a missionary is not mainly a career move or a travel plan. It is a calling that your church confirms, your character proves, and the field tests. This article walks through the honest path: the call and how it is examined, the character required, the role of the local church, training, and the real difference between going yourself and sending someone already there. We will not romanticize it.

Start with the call, and let it be tested

A missionary call usually begins as a settled desire to see people who have never heard the gospel come to Christ. That desire is good. Paul wrote that he made it his ambition to preach where Christ was not named (Romans 15:20). But a desire is not yet a call. It has to be examined.

Testing a call means asking hard questions over time. Does the desire last through ordinary seasons, or does it fade when the excitement wears off? Do others who know you well see gifts that match the work? Are you fruitful in evangelism and service where you already live? A person who cannot share the gospel with a neighbor is unlikely to do it more easily in a language he does not yet speak.

Be patient here. A call that cannot survive a few years of testing at home will not survive the field. Testing is not doubt. It is love, protecting you and the people you hope to reach from a decision made in a rush.

Character comes before competence

The New Testament sets the bar for those who lead and teach in terms of character, not talent. When Paul lists qualifications in 1 Timothy 3 and Titus 1, most of what he names is who a man is: self-controlled, hospitable, not quarrelsome, able to manage his own household, holding firmly to sound doctrine. Skills can be trained. Character is grown slowly, usually through trials.

This matters because the field magnifies whatever is already there. Distance from home, culture shock, loneliness, and slow results will expose pride, impatience, and hidden sin. Missionaries do not become new people when they board a plane. They become more of what they already were.

So the question is not only "can you do the work" but "are you the kind of person who should." Financial honesty, faithfulness in marriage, a teachable spirit, endurance under criticism. These are not extras. They are the ground everything else stands on.

The local church, not just your own conviction

In Acts 13 the Spirit sets apart Barnabas and Saul, and it is the church at Antioch that fasts, prays, lays hands on them, and sends them. The sending church is not a formality. It is the body that knows the worker, confirms the gifting, and stays connected through the years.

If you sense a call, root yourself in a healthy local church and make your desire known to your elders. Let them observe you, involve you, and speak honestly into your life. A missionary sent by a church that barely knows him is a missionary without a home base for accountability and care. You can read more about how we think about this in our page on accountability.

Affirmation from your church also protects you from self-deception. It is easy to mistake restlessness or guilt for a call. The people who have watched your life for years are a far better judge than your own strong feelings on a given Sunday.

Training, and counting the cost

Preparation varies widely by role and setting, but almost everyone needs grounding in Scripture, doctrine, and the basic work of evangelism and discipleship. Many also need language study and cross-cultural training. Some serve in support roles that ask for other skills entirely. There is no single track, and honest agencies will tell you so.

Count the cost plainly. Jesus told those who would follow him to sit down first and reckon whether they could finish (Luke 14:28). Supporting a Western missionary family on the field often runs on the order of $100,000 a year or more once travel, housing, schooling, and healthcare are added. That is not a criticism. It is a fact to plan around, for you and for the churches that send you.

Training also includes learning to raise and steward support well. If God calls you to go, he will provide, usually through the ordinary generosity of his people. Handle that money as a trust. Our approach to this is described under stewardship.

Going yourself, or sending those already there

Here is the part many guides leave out. Becoming a missionary yourself is not the only way, and often not the most effective way, to reach a given people. Much of the work among the unreached is now carried by national and indigenous pastors who already know the language, the culture, and the terrain.

A national pastor supported in parts of Asia on roughly $85 a month can often go where a foreigner cannot, stay when a foreigner must leave, and reach neighbors who would never open the door to an outsider. This does not make Western going wrong. It means the question is bigger than "should I go." It is "how can this people best be reached, and what is my part."

For some, the part is to go. For many, it is to send, pray, and partner with those already on the ground. Both are missionary work in the fullest sense. You can compare the two paths in our post on national pastors versus missionaries, and see how partnership works on our partnership page.

Whatever your part, do not romanticize it. The work is slow, the results are the Lord's, and the cost is real. But the aim is worth everything: that people who have never heard the name of Christ would hear it, believe, and be gathered into his church.
