As it is with all sin, rebellion originates within the heart. Long before it manifests itself in the individual’s actions, it finds life by taking root within his heart. The Lord described a rebellious generation by saying that they were “a generation that set not their heart aright, and whose spirit was not stedfast with God.” A man with a wicked heart and the wrong spirit cannot enjoy sweet fellowship with the Lord. As rebellion takes root in his heart, the rebellion pushes out the desires for prayer and for God’s word. Humility is crowded out because of pride and self-will to the extent that a man justifies, perhaps even with scripture, his rebellious spirit. His once soft heart becomes hardened because of the deceitfulness of sin.
Paul and Barnabas functioned similar to pioneer church planters who travel into unreached areas with the gospel. As they traveled, they faithfully preached the gospel and started churches with the goal of returning later to strengthen the believers. As Paul and Barnabas were planning their return to these areas, a conflict arose between them concerning who would accompany them on their journey. Barnabas desired to take a young man named John Mark, but Paul adamantly refused. Mark had accompanied them on the first trip, but departed from them and “went not with them to the work.” Paul felt as though he could no longer depend upon John Mark because of his earlier failure. The contention was so strong that Paul and Barnabas parted company and went their own separate ways. This is a sad narrative should it end here; however, there is much more to the story. Praise God that Paul later remarked of John Mark that “he is profitable to me for the ministry” (2 Timothy 4:11).
