Maybe it started on a short-term trip with your home church. Maybe it's a tug you can't quite explain, or a burden for a place and a people that won't let go of you.
However it started, if you've found yourself asking "how do I become a missionary?" you're not alone, and you're not starting from zero.
At Mesa Global, we've walked alongside hundreds of people who have asked that exact question, and we want to walk with you, too.
Global Worker or Missionary? A Note on Language
At Mesa Global, we intentionally use the term Global Worker more often than "missionary" because it is a broader term that fits more of our people. It is also a safer term to use when talking about people who serve in countries where missions work is controlled or brings greater risk.
Our Global Workers serve cross-culturally in a wide range of contexts, partnering with local leaders and churches rather than exporting our own models. We don't plant Mesa Global churches overseas. Instead, we come alongside what God is already doing through local believers, walking with them and learning from them. That posture–coming alongside rather than taking charge–is the heart behind everything else within this guide.
Is What You're Feeling a Calling, or Just an Interest?
It's a fair question, and an important one to sit with. A general interest in missions is a real and good thing: curiosity, passion, even a burden for a specific place or group of people. We believe that every follower of Christ is called to participate in missions in some way – often through prayer, support, and sending workers well. But a calling to go serve cross-culturally can feel like a big commitment, so it is best discerned in community, especially with your local church and Christian mentors. A calling is personal, but it's not something you have to figure out alone. Talking with a Mesa Global mobilizer is one of the best first steps you can take. Mobilizers are trained to help you process whether you're sensing a call to missions, and if so, whether now is the time to go or whether there's groundwork to lay first.
Missions is not only for people with years of ministry experience or a seminary degree. Most opportunities don’t require any formal training, and we equip you with relevant training before you go into the field. Most importantly, our mobilizers are looking for a few key qualities in candidates and a readiness to pursue cross-cultural missions. readiness to pursue cross-cultural missions.
What We Look for in a Global Worker
Beyond a sense of calling, we look for people who:
- Follow Jesus and want to keep growing spiritually
- Are adaptable and teachable
- Genuinely want to serve in a cross-cultural environment
- Are willing to raise financial support
- Are actively attending and serving in a local church
For married couples, both spouses need a clear call to missions. Of course, some roles carry additional requirements–a specific degree, teaching certification, or prior ministry experience, for example. A mobilizer will work through all of these options with you.
Talking to Your Home Church
If you don't currently have a home church, this is your first step. It’s not just a box we want to check. The local church is central to all that we do, and it’s the local church who actually sends a missionary out into the field. That sending role is one Mesa Global seeks to support and strengthen, not replace.
Every church handles this partnership differently, and that's okay. Your mobilizer will make sure you're actively serving with and attending a local church, and they will encourage you to have a conversation with your pastor or another leader early on in the process. As you continue on in the process, we'll also reach out to your home church directly for a reference.
The Practical Steps: From "I Feel Called" to "I'm on the Field"
Here's what the journey typically looks like for those pursuing two years of service or more. Note: shorter terms follow a simpler process.
- Mobilization & Discernment Calls: A mobilizer listens to your story, your passions, your experience, and prays with you as you explore potential ministry placements.
- Field Call: Once you're ready, your mobilizer connects you with a field or regional leader to talk through location and role.
- Application & Interview: This includes forms, a psychological assessment, references, a background check, and an interview.
- Mesa Global Orientation: A comprehensive, three-day online orientation called Entry Point.
- Ministry Partner Development (MPD): You're paired with a dedicated coach who trains, encourages, and holds you accountable as you raise support.
- Center for Intercultural Training (CIT): A seven-week residential, pre-field training program in Union Mills, North Carolina, designed for you and your family, if applicable. You'll train alongside workers from other mission agencies and even other workers going with Mesa Global.
The process may seem long to some, but it exists for real reasons: it roots you in Christ before you cross a cultural border, equips you with practical tools for communication, language learning, and field security, and builds community with other global workers who will become lifelong friends.
What Makes Someone Effective on the Field
Character matters more than your résumé. Resilience, teachability, adaptability, humility, and a growing faith in Christ consistently show up as the traits that carry people through hard seasons overseas. Because so much of our work involves equipping others, we also value a true willingness to pass along what you know and learn.
As you browse our opportunities database, you’ll see every kind of role–from teachers, medical professionals, businesspeople and musicians to church planters and outreach coordinators. In creative-access countries especially, a non-religious degree can open doors that a ministry degree can't. But across every context, flexibility is the trait that matters most.
Not Ready to Commit Long-Term? Start with an Internship
If a two-year term feels like a big leap, our 8–10 week summer internships are built for you. Serving as a Mesa Intern gives you a real taste of cross-cultural life and ministry in a shorter window, often helping confirm a calling and provide clarity for what’s next. Even if your internship doesn't lead to long-term service, it will change the way you see God’s mission and grow you spiritually.
You Won't Be Doing This Alone
Once you're on the field, Mesa Global surrounds you with:
- Member Care, including a New Member Mentor for your first two years, to help you remain healthy and sustainable in the field
- Professional counseling through a partner group experienced with the challenges of missionary life to provide care for you and your family
- A spiritual formation team offering retreats, webinars, and training, providing ongoing opportunities to grow in your life and ministry
- Regional leadership providing oversight and regular regional gatherings, to help you find community in the field
Missionary life has real challenges–loneliness even in a crowd, missing life back home, the strange grief of never feeling fully "home" anywhere again. At Mesa Global, we know that these challenges are real, and we seek to meet them with support and understanding. We walk alongside you through the highs and lows of ministry, so that you never have to do it alone. If anything you read caught your attention, the next right step isn't a five-year plan–it's a conversation. Start here and talk with a mobilizer about your calling and what God may be asking you to step into next.
