15:36-39 Some commentators have overestimated the "sharp disagreement"between Paul and Barnabas over John Mark, in my opinion.634The text says they disagreed vigorously over this issue, but there is no statement or implication that they ended up disliking each other, as some of the commentators have inferred. It seems that they were both led by the Holy Spirit to arrive at their respective conclusions regarding the wisdom of taking John Mark with them. Their separation, I infer, was friendly. Paul later wrote with respectful admiration of Barnabas (1 Cor. 9:6) and John Mark (Col. 4:10; Phile. 24; 2 Tim. 4:11). Their decision to go separate ways certainly resulted in greater gospel extension since more people became involved as fellow missionaries, and they covered more area in less time. Some Christians erroneously feel that any disagreement between believers is sinful, but there is no indication in the text that this difference of opinion was sinful.
Barnabas' desire to offer John Mark another opportunity was certainly commendable and godly even though Paul viewed it as unwise. Many of us would have dropped out of ministry had it not been for a gracious Barnabas who was willing to give us another chance after we failed.
15:40-41 Paul and Silas departed from Antioch with the church's blessing. This time they travelled by land north through Syria and Cilicia where Paul had been born and had previously labored. They strengthened the young churches in those Roman provinces.635
