How to Help Potential Missionaries Discern Calling

This resource equips church leaders to walk alongside individuals in their congregation who are discerning a call to global missions. It provides a biblical foundation for calling, highlights the global need, and introduces a practical framework—the Passion, Abilities, and Context (PAC) tool—for evaluating readiness and fit. Church leaders can use it to guide potential missionaries with clarity, wisdom, and care, ensuring they are well-prepared for the challenges and joys of cross-cultural ministry.

God is stirring hearts within your church. More and more members are recognizing their identity as “sent ones,” and some are beginning to explore whether they might be called to bring the gospel cross-culturally to places with limited access. When this happens, church leaders have the responsibility and privilege of walking with these individuals through the process of discernment.

Guiding people as they seek clarity on their life calling is one of the most meaningful aspects of local church leadership. When a member of the congregation initiates a conversation about what God might be doing in their life, it opens the door for church leaders to speak into their journey with wisdom and care. We long to see more believers actively seeking the counsel of their church community as they consider how God is leading them into the next season of their lives.

The Need for Guidance

When someone in the church is considering a call to global missions, the need for wise counsel becomes even more critical. This is not because missions is a superior calling, but because the implications of cross-cultural ministry are significant. A missionary must possess the character, knowledge, and skills necessary to faithfully share the gospel, make disciples, and plant churches in another cultural context. Without adequate preparation and assessment, there is a real risk of causing unintended harm—to the missionary themselves, to the team they join, to local believers, and to those they seek to reach.

Unfortunately, churches sometimes defer this process to missions organizations. While sending agencies play an important role in evaluating readiness and handling logistics, the local church is best positioned to assess and develop a potential missionary’s foundational character, spiritual maturity, and ministry capabilities.

As a church, you have the opportunity to come alongside members wrestling with a possible call to missions. You can help affirm and clarify that call—or, at times, lovingly redirect it. That external affirmation from church leadership provides the kind of spiritual support and confidence that is especially valuable for those preparing to live and serve in cross-cultural environments.

This resource is designed to support you, the missions leader, as you help church members discern their calling. It will equip you to:

• Define the idea of calling

• Reaffirm the biblical vision for cross-cultural missions and the current global need

• Provide a framework for guiding someone through their discernment process

Our hope is that this tool will help you engage potential missionaries with clarity, care, and conviction—and ultimately lead to stronger, healthier, and more faithful global workers being sent from your church.

Understanding Calling

The word calling is commonly used in church settings, but its definition—and importance—can often feel unclear. To help lay a biblical foundation, we recommend the article “Vocation: Discerning Your Calling” by Timothy Keller. In it, Keller offers a thoughtful and balanced view of what calling means.

He explains that every believer has a primary calling—to love God and love others in obedience to Christ. In addition, each person has a secondary calling—the specific ways we live out that primary calling in the world through our work and relationships. This secondary calling, or vocation, is how God provides for our needs and uses us to extend both common grace (through our skills and presence) and saving grace (through our gospel witness) to those around us.

Keller emphasizes that calling is discovered through a combination of passion, self-awareness of one’s abilities, and understanding the context in which one can serve. Importantly, he also dispels the notion of a sacred/secular divide—every vocation is a platform for ministry. A traditional 9-to-5 job is just as valuable in the kingdom as vocational ministry, as both can express God’s grace in distinct ways.

Helping a missionary candidate understand this framework of calling is crucial at the beginning of their discernment process. Throughout this resource, we will offer principles and practices to guide church leaders in walking alongside those considering missions—and in challenging those who may need further clarity.

Challenging Biblically

When walking with someone who is considering global missions, Scripture is the best place to begin. While this may seem obvious, we have often seen candidates make decisions based more on personal desires than on a biblical foundation. Grounding the conversation in God’s Word helps ensure that their discernment process is rooted in truth rather than emotion.

One of the key meta-themes in Scripture is God's redemptive plan to gather a people for himself from every tribe, tongue, and nation (Revelation 7:9). This global vision is not a peripheral idea—it’s central to God’s mission. And God’s chosen means of accomplishing this mission is through his people proclaiming the gospel.

Psalm 67:1–2 captures this clearly:

“May God be gracious to us and bless us; may he make his face shine upon us—so that your way may be known on earth, your salvation among all nations.”

Here, the blessing of God upon his people is not for their own sake alone, but so that his salvation would extend to the nations. This outward focus is seen consistently throughout the Old Testament:

• In Genesis 12:1–3, God promises Abraham that he will become a great nation to bless all nations.

• In Genesis 50:20, Joseph’s suffering leads to God’s name being known in Egypt.

• In 1 Kings 8:41–43, Solomon prays that the Temple would help foreign nations know God.

• In Isaiah 49:6, God’s servant is called to be a light to the Gentiles, not only Israel.

• 
  

This trajectory continues into the New Testament, where the global scope of the gospel is most clearly emphasized in the Great Commission (Matthew 28:18–20). Jesus commands his followers to make disciples of all nations—not just nearby, but everywhere, crossing cultural and linguistic boundaries.

However, some interpret the command to “go” as a universal call for all believers to become cross-cultural missionaries. While it is tempting to use this interpretation to stir commitment, we must be careful not to manipulate. Misapplication can lead to candidates pursuing missions without clarity or conviction.

Instead, we must help potential missionaries understand that there are multiple faithful responses to the Great Commission, such as:

• Praying for the nations

• Giving financially to missions

• Mobilizing others to go

• Welcoming refugees, migrants, and international students

At the same time, it should be emphasized that God’s primary means of reaching the unreached is still through people who go.

The writings and life of the Apostle Paul offer further clarity:

• Paul’s missionary journeys in Acts demonstrate intentional outreach to those who have never heard.

• In Romans 10:14–15, Paul reminds us that people cannot believe without first hearing the message.

• In Romans 15:20–21, Paul expresses his ambition to take the gospel where Christ is not yet known—namely, Spain.

The consistent biblical witness affirms that the gospel must be proclaimed for people to come to saving faith. While God may work through extraordinary means like dreams or visions, his usual method is through the obedience of his people.

As church leaders, we must handle Scripture with care—casting a compelling vision for global missions without pressuring people into it. Every believer should prayerfully consider whether God is calling them to cross-cultural ministry. But the decision must be made with sincere motives and deep conviction. The stakes are too high for anything less.

This means inviting others into God’s mission through a clear, biblical lens.

The Need

After grounding someone in the biblical vision for global missions, it is helpful to present the need for the gospel around the world. This step can deepen their awareness of why cross-cultural work is still essential.

Missiologists have compiled many helpful statistics that illustrate the global need:

• There are thousands of unreached people groups.

• Over 3 billion people have little to no access to the gospel.

• Approximately 180,000 people die each day without hearing the name of Jesus.

While statistics can be compelling, it’s important not to use them in a way that stirs guilt or shame. Condemnation is a poor motivator for lasting obedience. Guilt might move someone to action temporarily, but it will not sustain them through the inevitable challenges of living and serving cross-culturally. In fact, it can lead to frustration and bitterness when hardship arises.

Instead, we should approach these conversations with an invitational posture. Help people see the opportunity to participate in God’s global mission—not from obligation, but from joyful obedience. Frame the global need as part of God’s redemptive story and an invitation to join him in making his name known among the nations.

To make the global need more tangible, it can be helpful to contextualize it. Consider how the need compares to the access to the gospel in your church’s current environment. For example, if you work with university students, help them compare access to the gospel on their campus with that of students in unreached areas around the world. When individuals see the disparity and feel stirred to respond, they are often more open to discerning next steps.

Understanding both the biblical basis for missions and the global need provides a solid foundation for considering cross-cultural service. However, awareness of these things alone does not constitute a calling. Further discernment is needed to determine the specific role God is inviting someone to play in his mission.

One helpful tool for this next stage is the Passion, Abilities, and Context (PAC) framework outlined in Tim Keller’s article on vocation. This resource can assist church leaders in walking alongside individuals as they consider how their unique design fits into God’s global purposes.

Passions, Abilities, and Context

The Passion, Abilities, and Context (PAC) tool is a helpful framework for discerning vocational calling—whether in ministry, missions, or any other sphere of life. It is just as relevant for teachers, engineers, and stay-at-home parents as it is for those exploring global missions. While the general callings of being a Christ-follower, spouse, or parent remain relatively constant, vocational calling often varies in unique ways from person to person. This diversity is part of God's good design.

When helping a potential missionary discern their path, this tool provides a structured way to consider how their passion, abilities, and context align with a life of cross-cultural service.

Passion

Passion refers to the inner motivation or drive toward a specific kind of work. For some, this passion expresses itself through visible excitement. For others, it shows up more quietly—as a persistent draw toward a particular task or need.

When walking with someone considering missions, it's helpful to ask: What stirs their heart for the nations? A guiding Scripture we often use is Romans 15:20–21:

“My aim is to preach the gospel where Christ has not been named, so that I will not build on someone else’s foundation, but, as it is written:‘Those who were not told about him will see,and those who have not heard will understand.’”

This passage offers a vision of gospel proclamation where Christ is not yet known. Asking a candidate how this resonates with them can reveal much about their passion for missions. Is this burden something they carry already? Are they taking active steps toward it now, or is it simply aspirational?

True passion for global missions should be evident in a person's current life. If someone is not already sharing the gospel, engaging with people from other cultures, or practicing hospitality with internationals, then cross-cultural mission work may still be a distant goal rather than a present calling. A plane ride won’t create a missionary—passion must already be lived out.

It’s also essential to assess the motivations behind someone’s passion. Sometimes zeal for missions can be rooted in unhealthy desires, such as:

• Seeking significance or validation

• Trying to please others or meet expectations

• A desire for adventure or change

• Misinterpretations of Scripture

• A lack of direction in other vocational areas

These motives can often pass through assessments and interviews but will not sustain someone through the daily grind of overseas ministry. Your goal is to guide potential missionaries toward passion rooted in obedience to God and a heart for the lost—not personal ambition or emotional highs.

Finally, not every passionate person expresses their drive through visible enthusiasm. That’s okay. Some individuals are more quiet and contemplative but deeply motivated.

Signs of genuine passion may include:

• Consistently learning about global missions and cultures

• Pursuing relationships with people from other backgrounds

• Feeling burdened by the lostness of the world

These are all indicators that someone may be developing a sustainable passion for cross-cultural ministry.

Ability

In addition to passion, cross-cultural missionaries must have the abilities and giftings needed for the work. This includes spiritual gifts, natural talents, and learned skills—but also extends to character and maturity. The high cost of sending and the challenges of cross-cultural ministry make alignment between gifting and role especially important.

Timothy Keller’s article, “Discerning and Exercising Your Spiritual Gifts,” offers helpful insights for this area. While “gifting” is often the term used, we use the broader word ability to capture the full range of what’s needed—skills, knowledge, and character.

To help evaluate missionary readiness, we recommend the Upstream resource “12 Essential Traits in Developing Missionaries”. These traits provide a comprehensive grid for assessing a candidate’s preparedness across spiritual, emotional, relational, ministry, and personal domains.

Some of the unhealthy opposites of these traits to watch for include:

• Spiritual unhealth: A weak devotional life or ongoing bondage to sin

• Emotional unhealth: Defensiveness, lack of teachability, insecurity, or poor self-awareness

• Relational unhealth: Bitterness, difficulty with teamwork, or resistance to authority

• Ministry unhealth: Inexperience in evangelism or discipleship, or discomfort with other cultures

• Personal unhealth: Disorganization, poor self-care, or unreliability

Nobody will score perfectly across the board, but we look for the seed form of these traits. If they are not yet present, it’s best to encourage further personal development before pursuing missionary work. As always, the call to missions flows out of the deeper call to follow Jesus faithfully.

For churches looking for a starting point, tools like the resource “Missionary Assessment and Interview Guide” can provide structured ways to evaluate ability.

Context

With a biblical foundation in place, and after assessing a candidate’s passion and ability, the final piece to consider is context—the practical environment in which a missionary calling would be lived out.

Not every piece of the puzzle needs to be perfectly in place to begin exploring a calling. Some individuals may have strong understanding, passion, and ability, but their context—location, role, or opportunity—is still unclear. That’s okay. Context often requires time and discernment.

At this stage, we encourage churches to help potential missionaries explore the best-fit opportunities. Rushing this process or forcing someone into an ill-fitting team or location can be harmful. Instead, walk alongside them as they consider options that align with who they are and how God has shaped them.

For instance, someone passionate about discipling indigenous believers may not thrive on a team focused solely on frontline evangelism. In such cases, it’s crucial to help them find a context that suits their giftings and calling.

Helping someone discern the right context involves prayerful patience, collaborative exploration, and a willingness to wait for clarity. When a person’s passion and ability align with the right opportunity, it often brings joyful clarity to their missionary calling.

When One Is Missing

The calling to serve as a missionary can be helpfully discerned through a combination of passion, ability, and context. These three areas provide a comprehensive framework for evaluating readiness and fit. While an NFL quarterback might be satisfied completing two out of three passes, in discerning missionary calling, two out of three simply isn’t enough. Each area matters deeply. Here’s what can happen when one of them is missing:

Passion and Ability without Context

A candidate may have a deep passion for missions and the necessary skills to serve cross-culturally. But without the right context—whether in terms of timing, team, or role—long-term sustainability becomes unlikely. A poorly matched context often leads to frustration, burnout, or premature return.

Passion and Context without Ability

Passion and opportunity are not enough if the candidate lacks the necessary skills, character, or maturity to thrive in the role. Without ability, the work will suffer, the team will feel the strain, and the mission can be hindered. A heart that is eager to go must be paired with the competencies needed to serve effectively.

Ability and Context without Passion

Sometimes, individuals look at their life circumstances, recognize a need, and conclude, “Why not me?” While such willingness is admirable, if passion is missing, long-term engagement will be difficult. A calling that is only need-driven—without a deep internal burden or joy—can lead to discouragement and detachment.

For missionary calling to be clear and sustainable, all three components—passion, ability, and context—should be present. When they align, both in the heart of the individual and in the affirmation of the sending church and close community, a solid foundation for going is established. Internal conviction must be confirmed by external affirmation. When both are present, the missionary can move forward with confidence, even in the hardest days, knowing that the Lord is behind their going.

Sending with Wisdom and Confidence

Discerning a call to missions is both deeply personal and profoundly communal. This resource reminds us that while God may stir the heart of an individual, it is the local church that is best positioned to help confirm and clarify that calling. By grounding potential missionaries in Scripture, helping them assess their passion, abilities, and context, and walking with them through thoughtful discernment, churches can send global workers with confidence—workers who are equipped, affirmed, and joyfully aligned with God’s mission to make his name known among the nations.

Next Steps

The journey toward sending well happens one step at a time. Here are three ways you can continue growing in your ability to help church members discern God’s calling:

1. Set up a one-on-one meeting with a church member who has expressed interest in missions to begin a guided discernment conversation. Use the PAC (Passion, Abilities, Context) framework as a tool to listen well, ask thoughtful questions, and begin identifying where their calling might be emerging. 

2. Have a missionary candidate that you have identified fill out the “Missionary Assessment and Interview Guide” to help them evaluate areas of readiness.

3. Consider joining the Upstream “Assessment and Development Cohort” to learn more about healthy identification, assessment, and development of missionary candidates.
