Then after some days Paul said to Barnabas, “Let us now go back and visit our brethren in every city where we have preached the word of the Lord, and see how they are doing.” Now Barnabas was determined to take with them John called Mark. But Paul insisted that they should not take with them the one who had departed from them in Pamphylia, and had not gone with them to the work. Then the contention became so sharp that they parted from one another. And so Barnabas took Mark and sailed to Cyprus; but Paul chose Silas and departed, being commended by the brethren to the grace of God. And he went through Syria and Cilicia, strengthening the churches.
The initial urge to revisit the churches comes to Paul. Barnabas is willing but wants to include another, one not found faithful earlier. Their disagreement causes a split and two teams are formed where there had been one. The new teams continue, each going their own way and God’s work continues. As we are faithful to the work God has given us, obstacles that rise along the way change its shape and form but not His work. We can be found faithful to the work God has given each of us and He will bless; strengthen one another in the kingdom of God wherever we find ourselves.
