What is Missionary Work?

A Guide to Modern Missions

When you hear the term "missionary work," what comes to mind? For many, it brings up historical images or simple definitions. But in today's world, Christian missionary work is a dynamic, multifaceted calling that uses the unique gifts of believers to fulfill the Great Commission in diverse and strategic ways.



This guide will explore the purpose of missionary work, what missionaries actually do, and how organizations like SEND International equip them for effective, long-term ministry among the world's least-reached peoples.

The Core Purpose: 

Fulfilling the Great Commission

At its heart, the purpose of all missionary work is rooted in Matthew 28:19: "Therefore go and make disciples of all nations...". The ultimate goal is to bring the good news of Jesus Christ to those who have not had the chance to hear it.


However, modern missions is about more than just initial conversions. It's about establishing healthy, sustainable, and reproducing local churches that can carry the ministry forward for generations. It’s a long-term commitment to seeing a community transformed by the power of the Gospel.

What Do Missionaries Actually Do?

While every missionary's role is unique, their work often involves a blend of spiritual and practical activities designed to build relationships and serve the local community. A missionary's "job" can include:

Language and Culture Learning

The first and most critical task for any long-term missionary is to deeply learn the language and immerse themselves in the local culture. This is the foundation for building the genuine relationships needed for effective ministry.

Church Planting & Discipleship

The central spiritual work involves sharing the Gospel, leading Bible studies, baptizing new believers, and training local leaders to pastor and grow their own congregations.

Community Development & Service

Missionaries often use their professional skills to meet tangible needs. This can look like teaching English, providing medical care, coaching sports teams, or helping with agricultural projects. These activities build goodwill and open doors for spiritual conversations.

Support Roles

Not every missionary is a church planter. Modern mission teams rely on people with critical support skills, including teachers for missionary children, IT specialists, mechanics, administrators, and member care providers who ensure the entire team remains healthy and effective.
