Common Reasons for Leaving the Mission Field

Praise the Lord!

Most of us have been in church when a new missionary is commissioned. It is an exciting moment. Church leaders lay hands on the missionary, prayers are offered, the congregation celebrates, and a new chapter of ministry begins. 🙌🏻

But what many people do not realize is that within the first five years, nearly 50% of these new missionaries will leave the field; 70% of those departures will happen for preventable reasons (click HERE for more on these statistics).

Why Missionaries Leave

Many of the reasons missionaries leave are not dramatic crises but challenges that slowly build over time. Common preventable causes include:

• Burnout: Long-term stress, exhaustion, and emotional fatigue
• Financial strain: Insufficient or unstable financial support
• Relational conflict: Tensions with coworkers or mission leadership
• Isolation: Feeling forgotten or disconnected from home churches
• Unmet expectations: The reality of missionary life proving harder than anticipated

Mission work is deeply rewarding—but it is also incredibly demanding.

Connecting the Dots

So how does someone move so quickly from the excitement of commissioning to the discouragement that leads to leaving the field?

Missionaries face loneliness, fatigue, culture shock, and spiritual pressure on a daily basis. Many serve far from family, familiar culture, and consistent encouragement.

Multiple studies have shown that nearly half of missionaries who leave report ongoing mental health struggles that contributed to their decision.

What is the root of many of these issues?

The Prowling Lion

Scripture reminds us that missionary work is not only challenging—it is spiritual warfare.

The apostle Peter warns us:

"Your enemy the devil prowls around like a roaring lion looking for someone to devour." (1 Peter 5:8)

If the enemy wants to hinder the spread of the Gospel, who better to target than those sharing it every day?

The apostle Paul understood this reality firsthand. In 2 Corinthians 11:24–28, he describes beatings, imprisonment, shipwrecks, hunger, sleepless nights, and constant danger—all while carrying the burden of caring for the churches he helped establish.

The spiritual battle is real, and many times is the root cause of the physical, emotional, and mental struggles missionaries face.

How We Can Help Missionaries Stay

Great news is, strong support systems dramatically increase missionary retention by encouraging them through their struggles.

Churches can make a huge difference by:

• Pre-field preparation: Thorough training that better prepares missionaries for cross-cultural challenges
• On-field care: Regular communication, counseling, and occasional visits to the field
• Sustainable funding: Helping missionaries build stable, long-term financial support

Individuals can make a huge difference by:

• Communicating: Send encouraging emails, texts, or video calls—tools like Zoom and Google Meet make this easy
• Visiting: If possible, visit missionaries and get your hands dirty
• Supporting furloughs: Offer meals, housing, or transportation when missionaries return home
• Increasing support: If you have supported a missionary at the same level for years, consider giving them an unexpected raise
• Praying faithfully: Spiritual battles require spiritual weapons

Supporting missionaries does not have to be complicated. Small acts of encouragement and generosity can make a lasting difference.

And when the Church stands together behind those sent out to share the Gospel, missionaries are far more likely to remain on the field where they are desperately needed.
