Why did John leave Paul and Barnabas?
Why did John leave Paul and Barnabas in Acts 13:13, and what can we learn?

Setting the Scene

Acts 13:13: “From Paphos, Paul and his companions put out to sea and came to Perga in Pamphylia, where John left them to return to Jerusalem.”

• The missionary team—Paul, Barnabas, and John Mark—had just witnessed God’s power over Elymas in Cyprus (Acts 13:4-12).

• Crossing to Perga meant tackling rough terrain, hostile regions, and physical hardship.

• Scripture records the simple fact: John Mark “left them.” Later Paul calls it “deserted” (Acts 15:38).


Why John Mark Left

Scripture gives no explicit reason, but several factors emerge from the text and setting:

• Physical hardship

– The journey from sea level at Perga up to Pisidian Antioch rose over 3,500 feet through malaria-infested marshes.

– Paul later mentions an illness in this region (Galatians 4:13); Mark may have feared for his health.

• Homesickness and comfort

– Mark’s home in Jerusalem (Acts 12:12) was a center of early church life; being far away could have weighed heavily.

• Shift in leadership

– Up to Acts 13:13 it is “Barnabas and Saul”; afterward Luke writes “Paul and his companions.” Mark—Barnabas’s cousin (Colossians 4:10)—might have struggled with Paul’s new prominence.

• Ministry to Gentiles

– The team’s call to reach Gentiles (Acts 13:46-48) marked a dramatic expansion; Mark could have hesitated at the cultural challenge.

• Spiritual immaturity

– When crisis hit, he lacked the resolve of seasoned missionaries. Paul later viewed his departure as failure to persevere (Acts 15:38).


Lessons for Us

Endurance in Ministry

• God’s work often demands physical and emotional sacrifice (2 Corinthians 11:23-28).

• Commitment means pressing on even when conditions change.

Accountability and Trust

• Paul judged Mark’s departure seriously enough to withhold future partnership (Acts 15:38).

• Reliability is part of Christian character (Proverbs 25:19).

Grace and Restoration

• Barnabas believed in a second chance (Acts 15:39).

• Over time Mark proved faithful—Paul later wrote, “Get Mark and bring him with you, because he is useful to me in ministry” (2 Timothy 4:11; cf. Philemon 24; Colossians 4:10).

• God redeems failure; a former deserter became the author of the Gospel of Mark and a valued coworker.

Diversity of Gifts and Callings

• Barnabas and Paul split over Mark yet both continued fruitful work (Acts 15:39-41).

• God can multiply ministry even through disagreements, guiding each servant into roles suited to their growth and gifting.


Key Takeaways

• Perseverance matters—leaving a task unfinished can hinder gospel progress.

• Spiritual maturity grows through trial; early missteps need not define a life.

• The church is called to pair accountability with grace, holding high standards while offering restoration.

• God’s mission advances through imperfect people who turn back, learn, and serve again.
